Book excerpt: Lithium Air (Li/O2) batteries are energy conversion devices that produce electricity from the oxidation of lithium metal at the anode and the reduction of molecular oxygen at the cathode. These batteries are considered as promising rechargeable cells for high power applications due to their high power density ranging from 1000 to 2000 Wh/kg. However, one of the most significant challenges is the need to separate the metallic lithium anode from any oxygen or water-containing environment while at the same time allowing fast and efficient lithium ion transport through the electrolyte. Therefore, lithium ion conducting materials that are water and CO2 resistant are a prerequisite. Common materials used as anode protective films and/or Li+ conducting electrolytes for lithium air batteries are perovskite-type oxides (formula: ABO3). Perovskites are good candidates for this application because of their versatility, particularly in regards to ionic conductivity. In the present work, a low cost perovskite family such as SFO (SmFeO3) is developed as a lithium ion conducting material by the introduction of Li+ into its lattice. The perovskites have been synthesized using a solid-state reaction method (SSR) and characterized using different techniques such as powder X-ray diffraction (PXRD), scanning electron microscopy (SEM), energy dispersive X-ray Spectroscopy (EDS) and electrochemical impedance spectroscopy (EIS). The synthesized perovskites are based on samarium lithium ferrite and divided into two groups depending on the formal presence of vacancies in the stoichiometric formula. The first group (SLFO) with no formal vacancies has the stoichiometric formula of SmxLi1-xFeO2+x (where x = 0.1, 0.2, 0.3, 0.5 and 0.7). While the second group (SLFO*) was generated with less metal atoms than specified in the perovskite structure, thereby generating a structure with intrinsic vacancies and with the formula, Sm(x)Li([1-x] - [0.1] or [0.2]) FeO3-? (where x = 0.3, 0.4, 0.5 and 0.6). Finally, the effect of varying Li and Sm concentrations in both groups and vacancies created in the lattice for the second group, on the ionic conductivity is explored.

This book was released on 2018 with total page 112 pages. Available in PDF, EPUB and Kindle. Book excerpt: Despite commanding a huge market share of rechargeable batteries, current lithium ion batteries have safety concerns due to their use of flammable organic solvents as electrolytes. Successfully replacing the liquid electrolyte in a lithium ion battery with a solid electrolyte with comparable capability to the organic liquids would result in batteries that are safer to use, have a longer cycle life, and possess minimal self-discharge, wider operating potential and temperature window. Solid electrolytes currently have a limitation in that they do not match the ability of the organic liquids in conducting lithium ions because they almost always have ionic resistive components called grain boundaries in their microstructure. Appropriate combination of a glass with a perovskite-type ceramic that contains a lithium-ion conductive phase is shown to result in an amorphous composite having denser microstructure, better stability and no grain boundary effects. This is a pioneering breakthrough and a major upgrade to the ordinary crystalline ceramic, which, previously, had been shown to have one of the highest bulk ionic conductivity among solid electrolytes but greatly limited in application because of the much higher ionic resistance of its grain boundaries. In this research, different molar composition of glass and ceramics were melted and cooled using varying techniques, including a dual roller-quencher built from a rolling mill. A phase diagram for the mixture at different compositions was proposed and the composition giving a nucleation & growth morphology, where the lithium - ion conductive phase was the amorphous matrix was found to be one order higher in ionic conductivity than the ordinary Li0.5La0.5TiO3 perovskite-type ceramic. The results from other cooling rates and doping of the glass - ceramics with foreign ions were also reported and explained in this report.

This book was released on 2019 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this work, porous polymer-silica hybrid materials as a powder and thin film are synthesized and characterized. The preliminary study of their Li+ ionic conductivity properties are carried out as well. Here, the polymer electrolyte is embedded in silica matrix - polymer-in-ceramic approach. The hybrid powders are synthesized through sol-gel using conventional triblock (Pluronic, P123) and laboratory made bifunctional diblock amphiphilic copolymers as structure directing agents (SDA). In the first case, post-synthetic modification is used to functionalize the pore surface of silica with PEO. The second allowed to direct functionalization the pore surface with hydrophilic block (PEO) through extraction of hydrophobic block. Particle-free mesoporous silica films with hexagonally ordered and vertically oriented mesochannels are synthesized on electrode surface via electro-assisted self-assembly method under hydrodynamic condition. The resulting films are mesoporous (a diameter of 3 nm) and fully accessible. A film with thickness of 660 nm was grown in 200 s, and functionalized with PEO and then lithium salt through solution impregnation method. The ionic conductivity properties of hybrids were performed after shaping the powder as a pellet or with the hybrid film directly formed on the electrode surface. The results showed that the Li+ conductivity brought to the materials. The pellets have 40 % interparticle porosity and filling this with polymer electrolyte has positive effect on optimizing conductivity of the pellets (2.0 x 10-7 Scm-1 for 35 % filling and 6.8 x 10-7 Scm-1 for 100% filling at 25 °C).

Available in PDF, EPUB and Kindle. Book excerpt: Lithium-ion batteries are one of the most promising energy storage devices for their light weight and superior cycling stability. However, the state-of-the-art lithium-ion batteries cannot satisfy the ever-increasing market demand of high energy density electrochemical energy devices. Advanced lithium batteries based on novel electrode materials could provide higher energy density thus become a hot research topic.This dissertation will discuss the designs and applications of novel electrode materials to address the performance challenges for different types of energy storage devices. Chapter 2 provides a new strategy to fabricate a "lithium-free" all-solid-state battery. The 3D hybrid anode design improves the cycling stability of all-solid-state batteries by overcoming the commonly observed cell failure due to the electrode volume change and lithium dendrite growth. This design provides a promising approach towards a high energy density, long life, and low-cost all-solid-state battery technology. In Chapter 3, a concentrated ether--based electrolyte with LiTFSI and LiNO3 as cosalts is proposed, which enables stable cycling of a Li-SPAN battery. In addition to providing excellent protection for lithium metal anodes by forming the solid electrolyte interface (SEI), the electrolyte promotes the formation of a crystalline cathode electrolyte interface (CEI) on the SPAN surface composed of LiF and LiNO2. The CEI effectively prevents the formation of soluble polysulfide species and enables stable cycling of the Li-SPAN batteries. In Chapter 4, a V2O5-Si multi-layer composite anode is proposed and fabricated. The mixed conductive V2O5 layer effectively confines the volume change of Si layer and prevents the parasitic reactions between Si and electrolyte. This strategy enables the anode a long cycle life as well as a long calendar life while maintaining high energy density.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Abstract: In recent years the development of autonomous photo-rechargeable batteries has received growing attention. Especially highly integrated photobatteries based on multifunctional materials able to harvest sunlight and store charge carriers are the holy grail amongst such devices. Recently 2-(1-cyclohexenyl)ethyl ammonium lead iodide (CHPI) has been reported as multifunctional photoelectrode material for the design of highly integrated Li-ion photobatteries. CHPI is thereby believed to be able to reversibly intercalate Li-ions from polar carbonate-based electrolytes, typically used in Li-ion batteries (LIBs). Herein, CHPI is examined closer to investigate its stability against dissolution, the possibility of Li-intercalation and photo-assisted deintercalation, and its general behavior under illumination in standard carbonate-based electrolytes as well as in a newly developed low polarity electrolyte based on ortho-difluorobenzene (o-DFB). This study demonstrates that CHPI dissolves in contact with carbonate-based electrolytes while being stable in o-DFB-based electrolyte and that no Li-intercalation takes place in the latter. Furthermore, CHPI irreversibly photo-corrodes during illumination and photo-assisted deintercalation of lithium ions is not detected. These results lead to the conclusion, that CHPI is neither a suitable nor a stable material for the design of Li-ion-based photo-rechargeable batteries and similar behavior for other organic-inorganic lead halide perovskite materials is expected
