Poly(Ether-Ester)-Based Solid Polymer Electrolytes with High Li-Ion Transference Number for High Voltage All-Solid-State Lithium Metal Batteries

“…Lithium metal batteries (LMBs) using high theoretical specific capacity (3860 mAh g –1 ) and low negative standard potential (−3.04 V) lithium (Li) metal as anode are among the most attractive next generation rechargeable lithium-ion batteries (LIBs), regarding the rapid expansion market of electronic devices for higher energy density, longer cycle life, and high-performance energy storage systems nowadays. − However, the key issues that hinder the large-scale development and application of LMBs in traditional organic liquid electrolytes LIBs are the thermal instability of organic solutions and dendrite growth of Li metals, which may raise the safety risk of short-circuiting and thermal runaway, even causing flames or explosions. , In addition, due to the unsatisfied compatibility of Li metal anode and liquid electrolytes, stable and homogeneous solid electrolyte interphase (SEI) cannot be formed during the recurring plating/stripping process, which is susceptible to irreversibly damage and haphazard growth of Li dendrites while a rapid capacity losing and lower Coulombic efficiency will also appear due to the formation of irreversible “dead metal”. − …”

Effect of LLZO on the in situ polymerization of acrylate solid-state electrolytes on cathodes

“…[8][9][10][11] Thus, SSEs have been a research hotspot in recent years for high-performance lithium-based batteries. [12][13][14][15] Inorganic solid electrolytes such as oxides, 16,17 suldes 18,19 and halides 20 have excellent ionic conductivity, good thermal stability and incombustible properties. However, the inorganic SSEs are unstable versus the Li metal surface and/or atmosphere, indicating that the extra surface treatments are necessary for the ceramic.…”

Solid polymer electrolyte membrane based on cationic polynorbornenes with pending imidazolium functional groups for all‐solid‐state lithium‐ion batteries

“…Copolymerization of the above two monomers with NB monomer in the presence of Grubbs' 2nd catalyst to obtain bis-imidazole cationic functionalized benzobisabolene triblock copolymer. 18,19 The main chain structure of the copolymer serves as the backbone support, and the side chains are highly flexible, which facilitate the transport of lithium ions. Blending the prepared block copolymer with LiTFSI and prepared SPEM by solution casting method.…”
