Synthesis of lithium transition metal sulphides

摘要

A process for the production of a lithium transition metal sulphide such as lithium iron sulphide, the process comprising reacting a transition metal sulphide with lithium sulphide in a solvent comprising a molten salt or a mixture of molten salts. Lithium transition metal sulphides obtained using this process are also claimed and are useful in the production of electrodes, in particular for rechargeable lithium batteries.
