Li2 Mn2 O4
semiconductor· Li2 Mn2 O4
Li₂Mn₂O₄ is a lithium manganese oxide ceramic compound that functions as a cathode material in lithium-ion battery systems. This spinel-structured oxide is widely researched and commercially deployed in secondary (rechargeable) lithium batteries, particularly for applications requiring moderate energy density and enhanced thermal stability compared to layered oxide alternatives. Engineers select this material for cost-effectiveness, improved safety characteristics, and cycle life performance, making it especially valuable in stationary energy storage and certain portable power applications where raw energy density is less critical than reliability and cycle longevity.

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.
