Disclosed are a metallic nano-structure material in which an energy storage capacity based on electrochemical reaction with lithium is improved by 10 times or more compared to a conventional graphite material and power characteristics are excellent, an electrode composed of the metallic nano-structure material, and a lithium ion asymmetric secondary battery including the electrode as an anode. When using the electrode for the lithium ion asymmetric secondary battery, energy larger than with the graphite material can be stored with very thin thickness due to the high-capacity feature of the metallic material and the high-power feature can be achieved by the nano structure, such that energy density can be innovatively improved in the same weight condition when compared to a conventional lithium ion capacitor, and the lithium ion asymmetric secondary battery including the electrode can be used for renewable energy storage, ubiquitous power supply, heavy machinery, vehicle power source, etc. |
