· JVASP-116503· Li4Co3O7

Li₄Co₃O₇ is a lithium cobalt oxide ceramic compound belonging to the mixed-valence transition metal oxide family. While primarily of research interest rather than established industrial production, this material is investigated for energy storage applications, particularly as a potential cathode or active material in lithium-ion battery systems where its lithium content and cobalt redox activity offer opportunities for tuning electrochemical performance. Its notable feature compared to conventional layered oxide cathodes is the specific lithium-to-transition-metal ratio and crystal structure, which influences ionic conductivity and reversible capacity, making it relevant to researchers optimizing next-generation battery chemistry.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
