ELECTRODE FOR SECONDARY BATTERY, MANUFACTURING METHOD FOR THE SAME AND NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide an electrode for a secondary battery and a secondary battery suppressing deterioration in battery performance due to intervention of foreign substance which has slipped off from a collector, an electrode mixture layer or the like between the positive and negative electrodes.

SOLUTION: The electrode for the secondary battery has water soluble polymer 8 arranged on an end section of an electrode plate 1. This water soluble polymer prevents movement of slipped off substance from the plate or burr from a current collector metal generated when cutting the electrode plate or the foreign substance such as metal powder generated in manufacturing of the battery. Thus, short-circuiting and failure due to intervention of the foreign substance between the positive and negative electrodes can be suppressed when the secondary battery (nonaqueous electrode secondary battery) is formed.
