This book was released on 2022-08-25 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Commercial carbonate electrolytes with poor oxidation stability and high flammability limit the operating voltage of Li-ion batteries (LIBs) to ~4.3 V. As one of the most promising candidates for electrolyte solvents, sulfolane (SL) has received significant interest because of its wide electrochemical window, low flammability and high dielectric permittivity. Unfortunately, SL-based electrolytes with normal concentrations cannot achieve highly reversible Li+ intercalation/deintercalation in graphite anodes due to an ineffective solid electrolyte interface, thus undermining their potential application in LIBs. Here, a low-concentration SL-based electrolyte (LSLE) is developed for high-voltage graphite||LiNi0.8Co0.1Mn0.1O2 (NCM811) full cells. A highly reversible graphite anode can be achieved through the preferential decomposition of the dual-salt LiDFOB-LiBF4 in the LSLE. The addition of fluorobenzene further restrains the decomposition of SL, endowing uniform, robust and inorganic-rich interphases on the electrode surfaces. As a result, the LSLE with improved thermal stability can support the MCMB||NCM811 full cells at 4.4 V, evidenced by an excellent cycling performance with capacity retentions of 83% after 500 cycles at 25 ℃ and 82% after 400 cycles at 60 ℃. We believe that the design of this fluorobenzene-containing LSLE offers an effective routine for next-generation low-cost and safe electrolytes for high-voltage LIBs.

Available in PDF, EPUB and Kindle. Book excerpt: The increasing demand for electric vehicles and portable devices has revealed the potential of lithium-ion batteries (LIBs). However, conventional graphite-based LIBs fall short in providing sufficient energy density and power density, which hinders the development of electric vehicles and electric aircraft. Lithium metal anode material emerges as one of the most promising candidates for high energy density batteries (> 500 Wh/kg and > 1000 Wh/L) due to its exceptional theoretical specific capacities, lowest reduction potential, and low density. Nonetheless, the commercialization of lithium metal anodes faces challenges such as limited cycle lives caused by continuous dendrite growth and safety concerns arising from porous electrodeposited structures. Electrolyte engineering represents the most efficient approach to establish a compatible anode/electrolyte interphase (SEI) at a fundamental level. Despite significant research on the development of high-concentration electrolytes and localized high-concentration electrolytes, both suffer from reduced ionic conductivities and poor wettability towards thick electrodes. Liquefied gas electrolytes (LGEs) offer a promising alternative to enable high energy density lithium metal anodes due to their low viscosity, inherent pressure, electrochemical stability, and high fluorine content available for donation. However, it is crucial to prioritize addressing challenges related to the pressurized nature, relatively lower Li+/solvent coordination, and the flammability of fluoromethane (FM)-based electrolytes.To enhance salt solubility and expand the range of compatible salts, we propose replacing FM with the simplest ether, dimethyl ether (Me2O), due to its similar physical properties and more polar functional group, which potentially enables stronger Li+ solvation. When integrated with carbon monofluoride electrodes, Me2O-based LGE exhibits excellent performance at ultra-low temperatures, reaching as low as -70°C, and competitive fast-rate capabilities up to 6.25 C. However, low-concentration Me2O electrolytes face challenges in terms of relatively poor oxidative stability and flammability. To address safety concerns, we enhance the safety features of liquefied gas electrolytes by incorporating Me2O with other fire-extinguishing gas agents. The addition of fluorinated fire-extinguishing gases such as 1,1,1,2 tetrafluoroethane (TFE) and pentafluoroethane (PFE) significantly improves the safety of the formulated electrolytes. By utilizing the concept of localized highly concentrated electrolytes, we have developed a fire-extinguishing TFE-PFE-based LGE that enables stable Li/NMC622 cycling over 200 cycles at a cutoff voltage of 4.2 V. Moreover, these electrolytes can be successfully recollected after use, contributing to the sustainability of the LGE. In parallel studies, we have observed unique characteristics of Me2O-based electrolytes when high salt concentrations are maintained. Such electrolytes can maintain a liquid state under ambient conditions, facilitating electrolyte preparation and significantly reducing operating pressure, thereby lowering costs. The obtained saturated LiFSI-Me2O electrolyte exhibits excellent stability in Li-metal plating and stripping, achieving over 99.2% Coulombic efficiency for 1000 cycles. When combined with an SPAN electrode, the electrochemical performance of Li/SPAN demonstrates competitiveness due to the low solubility of polysulfides and the SEI derived from the salt. In conclusion, by introducing Me2O-based LGE, we present a promising direction for achieving high energy density, improved safety, ultra-low temperature operation, and sustainability in multiple Li-based batteries.

Book Synopsis Water in Lithium-Ion Batteries by : Futoshi Matsumoto
Download or read book Water in Lithium-Ion Batteries written by Futoshi Matsumoto and published by Springer Nature. This book was released on 2022-01-04 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the impact of water content in lithium-ion batteries (LIBs) as well as the reactivity of anodes, cathodes and electrolytes with water and processes that provide water-resistance to materials in LIBs. Water in LIBs which were constructed with anode, cathode and organic electrolyte containing lithium salts can degrade the cell performance and seriously damage the materials present. However, because a small amount of water in cells contributes to the formation of the solid electrolyte interphase, complete removal of water from cells lowers the battery performance and increases costs due to removal of water from the battery materials. This book presents the optimal concentration of water for each battery material along with appropriate removal methods and water-scavengers which were developed recently to establish both high performance and lower costs. Moreover this book describes the development of anodes and cathodes prepared by aqueous process and aqueous LIBs in which aqueous electrolytes containing lithium salts are used as an electrolyte. This book will be useful not only for academic researchers but also for company researchers who deal with LIBs.

Download or read book Invention and Development of Liquefied Gas Electrolytes for Lithium Ion Batteries and Beyond written by Yangyuchen Yang and published by . This book was released on 2020 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lithium (Li) ion batteries have been successfully commercialized under decades of development and made a great impact as energy storage devices for electronics industries. The demand keeps increasing and expands to larger areas like grid storage and electric vehicles, which calls for higher energy density, longer cycle life, and wider operation conditions. However, there have been little changes in electrolyte compositions since its commercialization and the balanced-properties of the conventional electrolytes can't meet the requirements for next-generation electrodes, such as Li-metal anode, high-voltage cathodes. Herein, we design and develop a novel electrolyte system from a unique direction. The use of molecules that are gases under standard conditions is liquefied under moderate pressure to form liquefied gas electrolyte for the first time. Combing the superior physical and chemical properties, the liquefied gas electrolytes show a wide potential window of stability and impressive performance in extended temperature ranges. Electrolytes using difluoromethane (DFM) and fluoromethane (FM) demonstrate excellent performance in a wide temperature range for electrochemical capacitor and 4-volt lithium-ion battery, respectively. Comprehensive approaches are applied to have a deeper understanding of liquefied gas electrolytes and further improve the overall performance. Tetrahydrofuran is first introduced as a cosolvent to improve the salt solubility and conductivity. The unique solvation structure and stable solid electrolyte interface enable improved Li-metal coulombic efficiency and rate capability in a wide temperature range down to -60°C. Besides, there are demands to further expand the upper-end boundary of both voltage and temperature window of liquefied gas electrolytes. Therefore, in a separate study, we formulate liquefied gas electrolytes using acetonitrile as a cosolvent and a higher salt concentration of 1.2 M for 4.5 V Li-metal batteries in a wider temperature range (-78~+75°C). Possibilities of using other liquefied gas solvents for Li-ion batteries are also been explored. A mixture of liquefied solvents is selected to improve safety. The electrolyte shows unique properties on fire extinguishing and one step recycling with excellent electrochemical performance.

Book Synopsis Lithium Metal Anodes and Rechargeable Lithium Metal Batteries by : Ji-Guang Zhang
Download or read book Lithium Metal Anodes and Rechargeable Lithium Metal Batteries written by Ji-Guang Zhang and published by Springer. This book was released on 2016-10-06 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides comprehensive coverage of Lithium (Li) metal anodes for rechargeable batteries. Li is an ideal anode material for rechargeable batteries due to its extremely high theoretical specific capacity (3860 mAh g-1), low density (0.59 g cm-3), and the lowest negative electrochemical potential (−3.040 V vs. standard hydrogenelectrodes). Unfortunately, uncontrollable dendritic Li growth and limited Coulombic efficiency during Li deposition/stripping inherent in these batteries have prevented their practical applications over the past 40 years. With the emergence of post Liion batteries, safe and efficient operation of Li metal anodes has become an enabling technology which may determine the fate of several promising candidates for the next generation energy storage systems, including rechargeable Li-air batteries, Li-S batteries, and Li metal batteries which utilize intercalation compounds as cathodes. In this work, various factors that affect the morphology and Coulombic efficiency of Li anodes are analyzed. The authors also present the technologies utilized to characterize the morphology of Li deposition and the results obtained by modeling of Li dendrite growth. Finally, recent developments, especially the new approaches that enable safe and efficient operation of Li metal anodes at high current densities are reviewed. The urgent need and perspectives in this field are also discussed. The fundamental understanding and approaches presented in this work will be critical for the applicationof Li metal anodes. The general principles and approaches can also be used in other metal electrodes and general electrochemical deposition of metal films.
