· K4 Li4 O4

K₄Li₄O₄ is an experimental lithium-potassium oxide compound classified as a semiconductor, representing research into mixed-alkali metal oxide systems. This material belongs to the family of advanced oxide semiconductors being investigated for potential applications in solid-state ionics, energy storage interfaces, and ceramic electrolytes, where the combined lithium and potassium content may offer tunable ionic conductivity and electrochemical stability. While not yet in mainstream industrial production, compounds in this chemical family are of particular interest for solid-state battery development and as functional ceramics where alkali-metal doping can enhance performance relative to single-alkali alternatives.
