Li2WS2
metal· JVASP-135376· Li2WS2
Li₂WS₂ is an experimental lithium-tungsten sulfide compound being investigated as a potential electrode material and solid-state electrolyte component for next-generation battery systems. This material belongs to the family of lithium metal chalcogenides, which are attracting research interest for their ionic conductivity and electrochemical stability in lithium-ion and solid-state battery architectures. While not yet commercialized at scale, compounds in this class are being developed to address current limitations in energy density, cycle life, and thermal safety of conventional battery technologies.
