Summary: Single-crystal LiNi0.6Mn0.1Co0.3O2 cathodes in ASSBs with PEO-based electrolyte exhibit higher Li+ diffusion coefficient, higher initial specific capacity, stable cycling performance, and exceptional rate capability compared to conventional polycrystalline LiNi0.6Mn0.1Co0.3O2 cathodes. The poor performance of polycrystalline cathodes is mainly attributed to structural deterioration and formation of a rock-salt phase. Single-crystal Ni-rich cathodes show promise in achieving ASSBs with high energy and power density.

Summary: Composite polymer electrolytes (CPEs) with Li6PS5Cl dispersed in solid polymer electrolytes (SPEs) based on PEO were prepared using solution casting method. The addition of Li6PS5Cl enhanced lithium-ion conductivity and interfacial stability, improving electrochemical properties. PEO-1 wt% Li6PS5Cl showed high lithium-ion conductivity and stable interface, leading to higher coulomb efficiency and better cycle stability in all-solid-state LiFePO4/Li batteries.

Summary: The deposition of polymer/ceramic layers on a lithium surface can create a strong barrier against dendrites. Different forms and types of ceramic were tested, and polymer/ceramic interlayers of a few micrometers were successfully deposited between the lithium and the PEO-based solid polymer electrolyte. The observed benefits of the polymer/ceramic layers include reducing charge transfer resistance, improving cycling durability, and avoiding dendrite formation.

Summary: Composite solid electrolytes are crucial for all-solid-state lithium batteries, which are considered the next-generation energy storage devices. Numerous studies have shown that fillers in composite solid electrolytes can improve ion transport behavior by optimizing the ion transport path. The performance is closely related to filler structure and its interaction with other electrolyte components. This review focuses on dimensional design of fillers, as well as ion transport mechanism and filler-electrolyte interaction in advanced composite solid electrolytes. Strategies for designing composite solid electrolytes with high room temperature ionic conductivity are summarized to assist research for high-performance composite solid electrolytes.
