· JVASP-48527· Li4Fe3CoO8

Li₄Fe₃CoO₈ is a lithium-based mixed-metal oxide ceramic belonging to the spinel or layered oxide family, combining iron and cobalt cations in a lithium-rich lattice. This material is primarily investigated in research contexts as a candidate for lithium-ion battery cathodes and energy storage applications, where the multi-metal composition aims to balance electrochemical performance, structural stability, and cost compared to conventional single-transition-metal oxides. The material's appeal lies in its potential to leverage cobalt's conductivity and iron's abundance to achieve improved cycle life and rate capability in next-generation battery 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.
