· JVASP-44082· LiFe2F5

LiFe2F5 is a lithium iron fluoride compound that belongs to the family of fluoride-based materials under investigation for energy storage and electrochemical applications. This is primarily a research-phase material rather than a commodity industrial compound; it is of interest to battery researchers and materials scientists exploring alternative lithium-ion chemistries and solid-state electrolyte systems. The material's notable characteristic is its fluoride composition, which offers potential advantages in ionic conductivity and electrochemical stability compared to conventional oxide-based cathode and electrolyte materials, making it relevant for next-generation battery architectures.
