NEGATIVE ELECTRODE FOR LITHIUM SECONDARY BATTERY, AND LITHIUM SECONDARY BATTERY INCLUDING SAME

摘要

A negative electrode for the lithium secondary battery is provided to prevent the stress concentration according to the volume change of the active material and the collision of active material particles in charging/discharging and to improve a battery characteristic by reducing the resistance at electrode. A negative electrode for the lithium secondary battery comprises a current collector and an active material layer formed on the current collector. The active material layer comprises an anode active material and plate type graphite and has the porosity of 20-80 volume %.
