Abstract
Official abstract text for this publication.
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) L 1-y Fe 1-x Mn x SO 4 F (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.
First claim
Opening claim text (preview).
The invention claimed is: 1. A material comprising particles of a fluorosulfate the structure of which corresponds to formula (I) Li 1-y Fe 1-x Mn x SO 4 F (I) in which 0<x≦0.1 and 0≦y<1, wherein said material essentially has a phase of triplite structure and optionally a phase of tavorite structure, the phase of triplite structure representing at least 50% by volume.
