METHOD FOR ESTIMATING THE SELF-DISCHARGE OF A LITHIUM BATTERY

摘要

The invention relates to 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, said method including charging the battery until a metal lithium layer is formed between the electrolyte and the negative electrode, measuring the open-circuit voltage (VOC) of the battery at two moments, and determining the self-discharge current from the change in the voltage measured between the two moments.
