LITHIUM BATTERY ELECTRODE, ITS MANUFACTURING METHOD, AND BATTERY USING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a lithium battery electrode having improved battery characteristics and reduced quality variation from the improvement of the permeation of an electrolyte into a battery in a battery using a membrane-like electrode manufactured by applying electrode mixture onto a metal foil, a lithium battery using the same, and a method of manufacturing the electrode. SOLUTION: An electrode (12) is manufactured by applying electrode mixture (13) containing a material for allowing a lithium ion to be electrochemically absorbed into and discharged to one side or both sides of a metal foil (14). A lithium battery uses a lithium battery electrode having partially or wholly at least one or more linear or needle-hole-like holes (16) less than 100 μm in maximum line width or maximum diameter, within 20 mm in diameter on the metal foil with the electrode mixture applied thereto and its manufacturing method.
