METHOD FOR MANUFACTURING ELECTRODE OF SECONDARY BATTERY

摘要

PURPOSE: A method for manufacturing an electrode of a secondary battery is provided to add a material for improving adhesion strength, by eliminating oil sticked to materials. CONSTITUTION: A method for manufacturing an electrode of a secondary battery comprises the steps of: mixing a binder which is a polyvilylidene fluoride with an organic solvent which is N-methyl pyrrolidone, after filling the binder and the organic solvent to a container; adding a polyphosphoric acid to the mixture; simultaneously stirring and injecting an active material, which is a carbon; coating a slurry of the active material to materials; hit-air drying in a condition of a low temperature of 100-150 degrees centigrade; and manufacturing a pole plate by cutting in predetermined size after roll-pressing. The polyphosphoric acid is added with 0.05-0.5weight percent for solid powder of a slurry mixture. The binder is 6-13weight percent for the solid power of the slurry mixture.
