VERFAHREN ZUM BETREIBEN EINER LITHIUM-IONEN-BATTERIE

摘要

The invention relates to a method for producing a lithium-ion battery comprising a positive electrode and a negative electrode arranged on either side of an electrolyte, the positive electrode comprising, as an active material, a lithium-based material, the method comprising the following steps: a) a step of depositing a film containing a lithium salt on the surface of the positive electrode before it is placed in the battery; b) a step of assembling the positive electrode, the negative electrode and the electrolyte; and c) a step of forming a passivation layer on the surface of the negative electrode with the lithium ions resulting from the decomposition of the lithium salt contained in the film by applying a first charge to the aforementioned assembly.
