ANODE FOR A LITHIUM RECHARGEABLE BATTERY AND LITHIUM RECHARGEABLE BATTERY USING THE SAME

摘要

An anode for a lithium rechargeable battery includes an active material layer that includes a metal-carbon composite active material including a carbonaceous active material and at least one active material selected from the group consisting of a metal or a metal oxide, graphite particles having surfaces that are coated or partially coated with a resin f, and a binder that binds and fixes the active material particles and the graphite particles to each other. The anode further includes a collector on which the active material layer is disposed. The resin-coated graphite particles maintain multiple conductive contact surfaces between the active material particles due to adhesiveness of the resin even when the volume of the metal-carbon composite active material particles is changed during charging and discharging, and prevent a reduction of the battery capacity and improve the lifetime of the battery.
