· JVASP-48324· Li4Mn7O2F14

Li₄Mn₇O₂F₁₄ is a lithium manganese fluoroxide ceramic compound being developed as a cathode material for advanced lithium-ion battery applications. This compound belongs to the family of mixed-anion ceramics that combine oxide and fluoride components to enhance electrochemical performance, and remains primarily in research and development rather than established commercial production. Engineers investigating next-generation battery chemistries with improved energy density, cycle life, or thermal stability would evaluate this material against conventional layered oxide cathodes.

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.
