This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The lithium-ion batteries (LIBs) are the most researched battery system nowadays. LIBs, since their commercialization in the 1990s, provide better gravimetric/volumetric energy density, higher voltage, and cycle life with lower self-discharge than previously developed battery systems. All those advantages made the LIB systems an excellent candidate as the power source for portable electronic devices, electric-powered vehicles, space vehicles, electricity grid storage, and future electric aviation. However, there is a limitation to developing higher-capacity lithium-ion batteries as we approach the practical limit of the presently used cathodes, which makes today's high-energy LIBs. Moreover, small-form-factor portable electric devices and large-scale applications of LIB systems for electric vehicles, space vehicles, electric and hybrid aircraft, and grid storage are all facing challenges of lower than required safety levels in today's LIBs. Thus, developing new technologies and components of batteries with higher energy density and safety levels is the most desirable research & development topic. In this case, the lithium-sulfur battery (LSB) system is an excellent candidate for increasing the battery system's energy, beyond the energy storage limit of today's LIBs. With ~650 Wh kg-1 of gravimetric energy density, Li-S battery (LSB) achieved more than two times the energy density of state-of-art LIBs (~250 Wh kg-1). Organic liquid electrolyte (OLE) is one of the essential components in LIBs due to its high ionic conductivity (10-2-10-1 S cm-1) and electrode wettability at ambient conditions. As the temperature rises, the lack of thermal stability and high flammability of OLEs becomes a significant challenge in designing a safe operable LIB. Even a moderately elevated temperature (>65℗ʻC) can severely diminish the useful capacity and cycle life and can pose thermal safety issues (such as fire and explosions). Pursuing safer electrolytes led battery researchers and manufacturers around the globe to a significant task in developing a high-conductivity, thermally-stable solid-state electrolyte (SE). Depending on material selection (polymer or inorganic ceramics or polymer-ceramic composite), the solid electrolyte can be incombustible, nonvolatile, nonflammable, and stable at elevated temperatures. Combining the concept of LSB (high energy) and SE (enhanced safety), researchers introduced high energy density, high safety all-solid-state batteries, particularly all-solid-state lithium metal batteries. My research involves understanding the performance and safety behavior of next-generation, high-energy, high-safety all-solid-state lithium batteries, including LSB and LIBs. In my study, we experimented with sulfur-infused carbon as high-capacity cathode materials. We infused the sulfur at different temperatures. We utilized carbon cloth, activated carbon on carbon cloth, and hierarchical porous carbon on carbon cloth as substrate. The cathodes were tested in the baseline liquid electrolyte-based lithium-sulfur battery. To increase the safety of the lithium-sulfur battery, we synthesized different solid electrolytes based on sulfides, such as lithium phosphorous sulfur bromine iodine (LPSBI) and lithium phosphorous sulfur chlorine (LPSCl). The selection of these Li+ conducting sulfides was based on different useful properties such as i) high Li+ conductivity, ii) high interfacial stability with lithium anodes, and iii) high compressibility required for cell fabrication at room temperature. For the synthesis of Li+ conducting sulfide solid electrolyte, we have developed a scalable synthesis route that includes material sintering in a furnace in an Ar glovebox and eliminated the risk of letting the material contact with air compared to the state-of-the-art procedure that involves sintering the materials in a volume constraint quartz tube. Learned the challenges of state-of-the-art rechargeable and primary LSBs. For the first time, we constructed and studied the performance of sulfide SE-based primary (non-rechargeable) LSBs. My research suggests that future research should address optimizing i) sulfur cathode loading, ii) stack pressure, iii) electrode kinetics to make solid-state lithium-sulfur a secondary battery. The lithium (Li) anode can undergo infinite volume change during the charge-discharge of LSBs. For example, if one starts with a Li thickness of 100 ℗æm, during discharge thickness of the Li anode can vary from 100 ℗æm to 0. This kind of Li volume change, especially when using SEs makes the pressure applied on the battery critical. Without proper pressure, the connectivity of LSB components (viz., anode, electrolyte, and cathode) will falter and make the battery dysfunctional. Thus, understanding the effect of pressure on the battery plays an important role in solid-state LSBs. So we studied the effect of pressure on lithium deposition (charge) and strapping (discharge) against an important sulfide SE (Lithium Phosphorus Sulfur Bromine Iodide, LPSBI). We adopted a unique charge/discharge protocol using asymmetric cell configuration and determined the maximum allowed stripping and deposition current density at various pressures. This research will facilitate future progress on rechargeable solid-state LSBs and other rechargeable solid-state LIBs. Finally, my research focused on understanding the safety (thermal, electrochemical, and environmental) of sulfide SE-based all-solid-state LIBs using high voltage cathode (lithium cobalt oxide, LiCoO2 and low voltage anode (graphite, C). Thermal safety has been evaluated using Differential Scanning Calorimetry (DSC) and electrical safety by monitoring the open circuit voltage of a fully charged battery at different temperatures up to 170℗ʻC. Environmental safety has been evaluated by measuring the quantity of released H2S gas. The thermal, electrochemical, and environmental safety data obtained on sulfide SE-based all-solid-state LIBs has been found superior to commercial-type organic LE-based LIBs.

Abstract: The rechargeable lithium ion batteries (LIB) are playing increasingly important roles in powering portal commercial electronic devices. They are also the potential power sources of electric mobile vehicles. The first kind of the cathode materials, LiXCoO2, was commercialized by Sony Company in 1980s, and it is still widely used today in LIB. However, the high cost of cobalt source, its environmental unfriendliness and the safety issue of LiXCoO2 have hindered its widespread usage today. Searching for alternative cathode materials with low cost of the precursors, being environmentally benign and more stable in usage has become a hot topic in LIB research and development. In the first part of this study, lithium nickel manganese cobalt oxide (LiNi0.6Mn0.35Co0.05O2) is studied as the electrode. The materials are synthesized at high temperatures by solid state reaction method. The effect of synthesis temperature on the electrochemical performance is investigated, where characterizations by, for example, X-ray diffraction (XRD) and scanning electron microscopy (SEM), for particle size distribution, specific surface area, and charge-discharge property, are done over samples prepared at different conditions for comparison. The electrochemical tests of the rechargeable Li ion batteries using LiNi0.6Mn0.35Co0.05 cathode prepared at optimum conditions are carried out in various voltage ranges, at different discharge rates and at high temperature. In another set of experiments, the material is adopted as anode with lithium foil as the cathode, and its capacitance is tested. In the second part of this study, the iron based cathode material is investigated. Lithium iron orthosilicate with carbon coating is synthesized at 700℃ by solid state reaction, which is assisted by high energy ball milling. Characterizations are done for discharge capacities of the samples with different carbon weight ratio coatings.

This book was released on 2014 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: Rapid advancements of techniques for the synthesis of Li-ion battery materials are critically needed to address the requirement of a clean and efficient transportation sector. The current research serves this goal by developing an approach to producing layered cathode materials with superior electrochemical performance for electric vehicles (EVs). Current widespread application of EVs is primarily limited by their short range and their high price, which is primarily driven by the cost of the battery pack. The cost of the battery pack is driven by the cost of the cathode material that empowers it. Novel, high throughput and inexpensive synthesis methods delivering nanostructured materials are a key to meeting these requirements. The synthesis techniques need to be scalable, robust, and reproducible while producing high-density materials for lithium ion batteries. To this end we advance spray pyrolysis for the synthesis of the layered NMC composite materials, which are showing high promise as a cathode material. Spray pyrolysis produces high purity materials, and the limited number of process parameters allows for low cost and excellent control over product properties and outstanding batch-to-batch reproducibility. Layered Li-excess composite materials show nearly twice the capacity of commercial LiCoO2 cells. The materials are inexpensive, have improved safety characteristics and long cycle life. Yet, as recently demonstrated, the materials suffer from an inherent layered-spinel phase change. This leads to a voltage fade over extended cycling, and this shortcoming needs to be addressed before commercial implementation is feasible. In this work spherical-shape layered xLi2MnO3*(1-x)LiNi1/3Mn1/3Co1/3O2 composites were synthesized. The relationship between composition and material stability under different synthesis conditions (350 °C - 800°C reactor temperatures, 0.5 - 2.5 M concentration, 6.6 - 10.4 lpm flow rates) were explored. We found that from among the compositions corresponding to x = 0.3, 0.5 and 0.7, the composition for x = 0.3, or Li1.14Mn0.46Ni0.2Co0.2O2, provides improved stability and the least amount of voltage fade while displaying capacities around 190 mAhg-1 after 100 cycles at C/10 rate at room temperature. At the same time, for x = 0.5, or Li1.2Mn0.54Ni0.13Co0.13O2, the material delivers 205-210 mAhg-1 discharge capacities at C/3 rate at room temperature after 100 cycles, but displays more voltage fade over cycling. This work demonstrated that the major process parameters (flow rate, reactor synthesis temperature and concentration) can be accurately controlled and the synthesis method is robust. The reproducibility of the process was evaluated using charge and discharge tests and the standard deviation for cycling tests was 4 mAhg-1 at C/3 rate based on 4 batches produced under identical conditions on different dates. This indicates excellent batch-to-batch reproducibility. Post-synthesis annealing temperature optimization was performed for cobalt doped samples at 850 °C and 900 °C and we found that annealing for 900 °C for 2 hours improves the cycling stability of the samples. We evaluated the effect of lithium content between 3.3 wt% excess and 3.3 wt% deficiency and annealed the materials for 2, 5 and 20 hours at 900 °C. This helped develop a fundamental understanding between surface area and internal structural changes related to the Li2MnO3 structural component of the materials. Spray pyrolysis uniquely allows for the accurate control of stoichiometry and composition to trace contaminant level at these concentrations. Furthermore, through a collaborative research between Argonne National Laboratory, X-Tend Energy, LLC and Washington University in St. Louis a novel, highly scalable patent-pending slurry spray pyrolysis process was developed, which allows the production of battery materials with excellent electrochemical performance and provides a general platform for oxide materials at greater than 50 gh-1 scale. This unique process is the only known solution to the hollow sphere issue that has challenged spray pyrolysis synthesis for decades, namely producing particles greater than 2[mu]m size with a solid (non-hollow) but porous interior morphology. Tap densities greater than 1.0 gcm-3 are achieved at greater than 50 gh-1 scale as compared to 0.4-0.6 gcm-3 at 2 gh-1 scale. Li1.2Mn0.54Ni0.13Co0.13O2 produced by this novel process delivered ~205 mAhg-1 discharge capacity after 100 cycles at C/3 rate at room temperature, reproducing the electrochemical performance of the laboratory scale synthesis process and meeting or exceeding the performing of materials produced by co-precipitation. Voltage fade was addressed in the latter part of the work by varying the compositional ratio and using trace elemental doping. Results demonstrated for the first time that by selectively doping the xLi2MnO3*(1-x)LiNi1/3Mn1/3Co1/3O2 materials voltage fade can be reduced, as indicated by dQ/dV curves. The spray pyrolysis process for xLi2MnO3*(1-x)LiNi1/3Mn1/3Co1/3O2 materials, in particular for layered Li1.2Mn0.54Ni0.13Co0.13O2 displayed the highest capacity (c.a. 205-210 mAhg-1 after 100 cycles at C/3 rate at room temperature) among all cathode materials synthesized via spray pyrolysis to date.

This book was released on 2017 with total page 146 pages. Available in PDF, EPUB and Kindle. Book excerpt: Energy storage in the 21st century has become one of the most critical requirements to maintain sustainable development and a growing global economy. Today, the advancement of lithium-ion batteries is being taken to the next level with targeted applications being electric vehicles (EVs) and grid storage. Current widespread application of EVs is primarily limited by their short range and high price, which are significantly driven by the cost of the battery pack. The cost of the battery pack is driven by the cost of the cathode material that empowers it.The most common conventional synthesis method of cathode materials is co-precipitation, which includes long processing time and complex steps. Moreover, poor batch-to-batch uniformity due to differences in solubility and diffusivity of precursors further hinders large-scale implementation. To reduce energy consumption during production, and improve homogeneity of the product, we use spray pyrolysis for synthesizing multi-component metal oxide cathode materials. Spray pyrolysis, a promising development for larger scale synthesis in industry, requires shorter residence time in the reactor, eliminates washing and purification steps, and achieves excellent batch-to-batch reproducibility.Lithium, manganese-rich layered cathode material (LMR-NMC) has been studied intensively in the past decades and is one of the most attractive cathode materials under development. Its ability to reach discharge capacity above 200 mAh g-1 and low cobalt content make it a promising candidate for cathode material of electric vehicles. 0.5Li2MnO3·0.5LiMn1/3Ni1/3Co1/3O2 (Li1.2Mn0.54Ni0.13Co0.13O2) is currently the most widely studied chemistry. Yet, as recently demonstrated, the materials suffer from an inherent layered-spinel phase change. This leads to capacity and voltage fade over extended cycling, and this shortcoming needs to be addressed before commercial implementation is feasible.In the first part of the dissertation, voltage fade was addressed by trace elemental doping. Results demonstrated for the first time that by selectively doping the LMR-NMC materials, voltage fade can be reduced. The aluminum doped Li1.2Mn0.54Ni0.13Co0.13O2 demonstrated improved capacity retention of 99.4 % comparing to 91.5 % of the undoped material after 100 cycles. Furthermore, Atomic Layer Deposition (ALD) was used to modify the surface of Li1.2Mn0.54Ni0.13Co0.13O2 with thin layer CeO2, aiming to decrease voltage and capacity fade by increasing the substrate conductivity and setting a barrier for metal dissolution. The optimal CeO2 film thickness was 2.5 nm deposited by 50 cycles of CeO2 ALD. The cyclic stability improved to 60 % capacity retention after 400 cycles at C/1 and 55 °C. The CeO2 coating also reduced voltage fade.In addition, with the rising interest in sodium-ion battery research, tunnel structure sodium manganese oxide cathode materials were synthesized via spray pyrolysis. The materials demonstrate rod-like morphology after annealing. Optimal electrochemical performance was obtained from the sample produced with a Na/Mn precursor ratio of 0.50, which yielded phase pure Na4Mn9O18 structure. A discharge capacity of 115 mAh g-1 is reached for this material in the first cycle and the material demonstrates good cycleability and rate performance. This demonstrates the versatility of spray pyrolysis and its ability to synthesize a wide range of material with different structure and morphology.In later part of the work, a low temperature flame spray pyrolysis (LT-FSP) process is developed for the synthesis of Li1.2Mn0.54Ni0.13Co0.13O2. High water content ethanol was used as a fuel and a swirl-stabilized burner was used to achieve stable operation at the low reactor temperature, which is lower than can be attained via traditional FSP. The effects of reactor temperature, which is controlled via altering ethanol concentration, on the physical properties and the electrochemical performances of the synthesized materials were characterized. Li1.2Mn0.54Ni0.13Co0.13O2 synthesized with 25 wt% ethanol showed the best results and delivered a discharge capacity of 203 mAh g-1 after 100 cycles under C/3. It also achieved good rate capability showing 201 mAh g-1 and 169 mAh g-1 under C/2 and C/1, which are comparable to state-of-the-art performances. The production rate of LT-FSP also reaches 90 g h-1.In addition, LT-FSP was used to investigate the seed loading density of slurry spray pyrolysis. Slurry spray pyrolysis is the only known solution to the hollow sphere issue that has challenged spray pyrolysis synthesis for decades, namely producing particles greater than 2 om size with a solid (non-hollow) but porous interior morphology. Tap densities achieved 1.1 g cc-1 with 32 wt% of seed loading, which is half the amount of what was previously demonstrated. Li1.2Mn0.54Ni0.13Co0.13O2 produced by slurry spray pyrolysis reproduces the electrochemical performance of the conventional spray pyrolysis, meeting or exceeding the performance of materials produced by co-precipitation.

Chemists, physicists, electrochimists, and engineers all are involved in the research and development of materials, techniques, and theoretical approaches. This science is one of the great triumphs of the second part of the 20th century. For nearly a century, development of materials for solid-state ionic technology has been restricted. During the last two decades there have been remarkable advances: more materials were discovered, modem technologies were used for characterization and optimization of ionic conduction in solids, trial and error approaches were deserted for defined predictions. During the same period fundamental theories for ion conduction in solids appeared. The large explosion of solid-state ionic material science may be considered to be due to two other influences. The first aspect is related to economy and connected with energy production, storage, and utilization. There are basic problems in industrialized countries from the economical, environmental, political, and technological points of view. The possibility of storing a large amount of utilizable energy in a comparatively small volume would make a number of non-conventional intermittent energy sources of practical convenience and cost. The second aspect is related to huge increase in international relationships between researchers and exchanges of results make considerable progress between scientists; one find many institutes joined in common search programs such as the material science networks organized by EEC in the European countries.

This book was released on 2017 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: New-generation low-emission transportation systems demand high-performance lithiumion (Li-ion) batteries with high safety insurance at broad operable temperatures. Highly conductive solid electrolyte is one of the key components for such applications. The objective of this thesis is to synthesize and characterize aluminum doped lithium titanium phosphate, i.e. Li1+xAlxTi2-x(PO4)3 (LATP), one of the solid-state electrolytes for potential applications to all solid-state lithium-ion batteries. In this research, sol-gel method and onestep solid-state reaction approaches were explored and critical processes were optimized towards maximizing lithium ion conductivities at room temperature. The impacts of the processing conditions on the structures, morphologies, compositions of the LATP products, and lithium ion conductions were presented. Particle growth kinetics and lithium ion conduction mechanism were briefly discussed. The highest conductivities of LATPs achieved via the sol-gel and solid-state synthesis are 1.24E-04 S/cm and 1.86E-04 S/cm, respectively, exhibiting the feasibilities of applying them to all-solid-state Li-ion batteries.
