  • For high energy density and processability of ASBs, the development of sheet-type electrodes and SE films is imperative. To deal with this issue,
    our group has been focusing on customizing solvent processing to achieve compatibility with sulfide SEs. New fabrication protocols for
    mass-production of ASBs, such as the fabrication via the infiltration with SE solutions, have also been developed. Inorganic SE materials have narrow
    intrinsic electrochemical windows, which provokes the need of the passivation of SEs for the reversible operation of all-solid-state batteries.
    In particular, the adoption of conventional LixMO2 (M = Ni, Co, Mn, Al) cathode materials to all-solid-state Li-ion or Li batteries (ASLBs) suffers from
    huge interfacial resistances. In-depth understanding on the evolution at the electrode−SE interfaces is required and imperative for the practical
    development of high performance ASLBs.

  • Polymeric binders in the ASBs electrodes could buffer electro-chemo-mechanically derived stress and strain upon cycling at the expense of Li ionic
    contacts. Li-ion conductive binders that are applicable to wet-slurry process greatly increased electrochemical performances. Currently, the highly

    advanced binders featured sufficient mechanical property (e.g. flexible, highly adhesive) and functionality (e.g. highly Li+-conductive) are being
