LITHIUM SECONDARY BATTERY

摘要

The present invention relates to a lithium secondary battery comprising an anode and a cathode, wherein the anode includes a first anode active material consisting of a carbon-based material and a second anode active material with an initial charging and discharging efficiency lower than that of the first anode active material, and the initial charging and discharging efficiency of the anode is lower than that of the cathode. The present invention provides a lithium secondary battery that can realize a high output by significantly decreasing the resistance at a state of charge (SOC) in a low region.
