ABSTRACT:
The present invention relates to a punched electrode and a rechargeable lithium battery using the same, and more particularly to a punched electrode and a rechargeable lithium battery using the same that can improve cycle life, capacity, and safety characteristics of the battery. The present invention can improve cycle life, capacity, and rate characteristics etc. of the battery by making the impregnation rate of an electrolyte higher and by uniformly controlling the impregnation degree, and it can improve safety properties of the battery by preventing lithium deposition such that a uniform electrode reaction occurs, through punching out a hole in an anode, an anode/cathode, or an anode/cathode/separator of an electrode group that comprises the inner part of the lithium secondary battery.
