· Li4 Cu2 P2

Li₄Cu₂P₂ is an experimental ternary semiconductor compound combining lithium, copper, and phosphorus elements. This material belongs to the family of phosphide semiconductors and is primarily of research interest for its potential in energy storage, solid-state electrolytes, and optoelectronic applications. While not yet widely commercialized, compounds in this material system are investigated for next-generation lithium-ion batteries and as precursors for functional semiconductor devices due to the tunable electronic properties afforded by mixed-metal phosphide structures.
