Since the introduction of the first Li-ion battery by Sony in the nineties, demand for batteries with enhanced performances is increasing. LIB are widely used in laptop, cellular phones, electronic products (cameras, mp3 readers,…). They also penetrating the market of power tools and are studied also as candidates in hybrid/electric vehicles.
Conventional materials for cathodes are oxides such as LCO, NMC or NCA, spinelles phases or olivine structures (LFP).
Sulfate-based materials are interesting as they should theoritically have higher potential than phosphate-based materials.
The invention described a new family of fluorosulfate material having a triplite structure with its synthesis via dry process
Members of this family are the Fe/Mn solid solution LiFe1-xMnxSO4F.
Synthesis were made at a laboratory scale and electrochemical tests were done on the obtained powders.
Easy synthesis (fast and economic)
Good electrochemical performances
Operating voltage of 3.9V (to be compared with 3.6 V of LiFeSO4F or 3.45 V of LFP)
Cathode material in LIB.
