· LiFePO4

Lithium iron phosphate (LiFePO₄) is an inorganic ceramic compound that serves as the cathode material in lithium-ion battery cells. It is valued in the energy storage industry for its thermal stability, long cycle life, and inherent safety characteristics compared to other lithium cathode chemistries. LiFePO₄ has become the preferred choice for applications where reliability and safety outweigh the need for maximum energy density, making it dominant in stationary energy storage, electric vehicle powertrains (particularly for cost-sensitive segments), and portable power systems.

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.
