PREPARATION METHOD OF ELECTRODE FOR LITIUM RECHARGEABLE BATTERY

摘要

PURPOSE: A manufacturing method of an electrode is provided to reduce the internal resistance between a metal current collector and an electrode active material through two heat treatment processes and to improve the output performance of an electrode by improving electrochemical stability in an electrode material. CONSTITUTION: A manufacturing method of an electrode for a lithium secondary battery comprises a step of manufacturing a slurry mixture by mixing an active material powder, a binder powder, and a conducting powder; a step of making the mixture penetrate into the inner pores of metal foam, conducting a first heat treatment, and forming an electrode layer; a step of a pressing the electrode layer; and a step of conducting a second heat treatment under a reduction atmosphere.
