LITHIUM SECONDARY BATTERY

摘要

A decrease of the irreversible capacity, an increase of the discharge capacity of a negative electrode for a lithium secondary battery is achieved, together with an improvement of output power density and cycle characteristics of the lithium secondary battery. Carbon material is used for the negative electrode that adsorbs or bears an organic compound having a larger partition coefficient in the electrolysis solution than carbon particles. The above organic compound can be added to the electrolysis solution to achieve the same aims.
