The performance of Li-ion batteries mainly depends on electrode active material properties. However, the advanced characterization of obtaining the essential electrode materials properties is extremely required for electrode materials R&D. We developed the world＇s first single-particle electrode measurement, which shows precise electrochemical measurements of obtaining the essential electrode materials properties. Single-particle electrode measurement will become the vital characterization technology for electrode materials R&D in Li-ion batteries as well as advanced rechargeable batteries.

The aim of this study was to develop of high safety, high performance sulfide-based all-solid-state Li-ion battery (ASSLIB). The ASSLIB composes of a flexible, high ionic conductive,moisture insensitive sulfide-based solid-state electrolyte (SSE) film, Si/C composite anode material with self-healing polymer binder, high capacity LiNi0.8Co0.1Mn0.1O2 (NMC811) composite cathode,garnet-in-polymer solid composite interlayer to prevent decomposition of sulfide-based SSE with electrode materials.
