· JVASP-48148· Li2Co2Si2O7

Li2Co2Si2O7 is a lithium cobalt silicate ceramic compound that belongs to the silicate ceramic family, characterized by a crystalline structure combining lithium, cobalt, and silicate phases. This material is primarily investigated in research contexts for electrochemical applications, particularly as a potential cathode or electrolyte material in lithium-ion battery systems, where its ionic conductivity and structural stability are of interest. While not yet widely deployed in mainstream commercial products, lithium cobalt silicates represent an active area of development for next-generation energy storage technologies seeking alternatives or complements to conventional layered oxide cathodes.
