· Li4 Co2 Si2 O8

Li₄Co₂Si₂O₈ is a lithium-cobalt silicate ceramic compound that belongs to the class of layered oxide semiconductors, synthesized primarily as a research material rather than a commercial industrial product. This compound is of interest in battery materials research and solid-state electronics development, where cobalt-containing lithium silicates are investigated for potential applications in advanced lithium-ion battery cathodes and ionic conductors; it represents an experimental composition within the broader family of lithium transition-metal silicates, which continues to attract academic and industrial attention as alternative architectures to conventional spinel and olivine cathode materials.
