LiFeS2
metal· JVASP-50367· LiFeS2
LiFeS2 is an iron-lithium sulfide compound that functions as a cathode material in primary (non-rechargeable) lithium batteries, particularly in high-energy-density applications where long shelf life and reliable performance under demanding conditions are critical. This material is primarily researched and deployed in specialized battery chemistries rather than mainstream consumer electronics, making it notable for applications requiring extreme reliability, wide temperature tolerance, or extended storage periods without degradation. Engineers select LiFeS2-based batteries when energy density, thermal stability, and predictable discharge curves outweigh the cost considerations of advanced lithium chemistries.

Export Control
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.
