Development of a carbon material for negative electrode of lithium-ion battery

The suitability of a number of individual carbon materials for making lithium-ion battery anodes has been examined, their electrochemical activity in the reaction of reversible lithium intercalation from solutions of LiClO₄ and LiPF₆, in solvents based on propylene carbonate, dimethoxyethane, ethylene carbonate, and diethyl carbonate has been studied. A similar study was made on composite electrodes consisting of two carbon components. An optimal composition of the carbon material, promising for usage in lithium- ion batteries, has been found.
