· Li4 Cu1 Si2 O7

Li₄Cu₁Si₂O₇ is an experimental mixed-metal oxide semiconductor compound combining lithium, copper, and silicon in an anionic oxide framework. This material belongs to the family of lithium-based ceramics and is primarily investigated in research settings for its potential electrochemical and optoelectronic properties, rather than as an established commercial material. Interest in this composition stems from the combination of lithium's electrochemical activity with copper's variable oxidation states and silicon's glass-forming capability, making it relevant to energy storage and photovoltaic research communities exploring alternatives to conventional battery and photocatalytic materials.
