CATHODE MIXTURE FOR LITHIUM SECONDARY BATTERY AND LITHIUM SECONDARY BATTERY USING SAME |
摘要 |
An anode composition for a lithium secondary battery includes an anode active material, a binder, and a conductive material. The active material includes a plurality of anode active material particles, each of which includes a core made of metal or metalloid allowing alloying or dealloying with lithium, or a compound containing the metal or metalloid; and a shell formed at an outer portion of the core and having Ketjen black. The conductive material includes carbon nano fiber. The anode composition uses a metal-based anode active material that may controls the volume expansion, and also uses conductive material with excellent dispersion so that the life characteristic of the battery may be improved. |
