Abstract
A method for determining the self-discharge current of a lithium-ion battery provided with a positive electrode, a negative electrode, and an electrolyte arranged between the positive and negative electrodes includes charging the battery until a metal lithium layer is formed between the electrolyte and the negative electrode, measuring the open-circuit voltage of the battery at two moments, and determining the self-discharge current from the variation of the voltage measured between the two moments.
