▎ 摘  要

NOVELTY - Anode comprises an anode active material comprising a carbon-based material and a metal-based compound, a binder, and a multi-composite conductive agent comprising a carbon-based conductive agent and a metal-based conductive agent having different physical properties and shapes. USE - Anode for lithium secondary battery. Uses include but are not limited to electric vehicles, power storage devices, and personal information technology (IT) devices. ADVANTAGE - An anode containing a multi-composite conductive agent is provided where multi-composite conductive agent is capable of securing lifetime stability by improving the reactivity of graphite and maintaining the stable electrical conductivity of a silicon compound whose usage will increase, maximizing the energy density of a lithium secondary battery by minimizing the contents of a conductive agent and a binder in the anode, and improving rapid charging, high-power discharging, and lifespan characteristics by improving electrical conductivity and electron mobility in the anode. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a lithium secondary battery, which comprises an anode, a cathode, a separator, and an electrolyte.
