## Description

- description: Solid-state lithium metal batteries, assumed to show improved safety
    and high energy density, have garnered growing interest. Nevertheless, establishing
    an effective ionic conduction pathway within the composite positive electrode
    remains challenging, especially with high-active- materials mass-loading in the
    electrode. Herein, we develop a high-active-mass loading positive electrode for
    solid-state Li metal rechargeable batteries, optimized for operation at an elevated
    temperature of 60°C. The electrode is based on NMC622 as active material, incorporating
    the ionic liquid Pyr14TFSI and LiTFSI (combined-electrolyte, cE). The positive
    electrode membranes are successfully prepared by preventing undesired gelation
    of the slurry solution and seamlessly integrating them with a thin-film multilayer
    hybrid solid electrolyte. Notably, the NMC622-based electrode with 10 wt% of cE
    achieves a specific capacity exceeding 160 mAh g−1 at a high mass loading of 40 mg
    cm−2. The methodology demonstrated in the present study highlights the potential
    of incorporating a cE into cathode compositions for high energy density solid-state
    Li metal batteries.
