LiMn2O4
ceramic· LiMn2O4
LiMn2O4 is a lithium manganese oxide ceramic compound primarily known as a cathode material for lithium-ion batteries. It is valued in battery applications for its cost-effectiveness, thermal stability, and adequate energy density, making it a practical alternative to higher-performance cathode chemistries in applications where raw material cost and safety are priorities. This spinel-structured oxide is particularly relevant in consumer electronics and power tools where moderate performance requirements justify lower material costs compared to nickel- or cobalt-based alternatives.

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.
