Abstract
A fluoro material is provided for use as an electrode active material as well as a process tar producing it. The material includes particles of a fluorosulfate which corresponds to formula (I) L1-yFe1-xMnxSO4F (I) in which 0<x≦1 and 0≦y<1. The material includes a phase of triplite structure and optionally a phase of tavorite structure, the phase of triplite structure representing at least 50% by volume. The material may be obtained from precursors of the elements of which it is constituted, via a ceramic route, via an ionothermal route or via a polymer route.
