METHOD OF MANUFACTURING NEGATIVE ELECTRODE PLATE FOR NONAQUEOUS ELECTROLYTE SECONDARY BATTERY, AND METHOD OF MANUFACTURING NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

Document Type and Number:

Japanese Patent JP2014194864

Kind Code:

A

Abstract:

PROBLEM TO BE SOLVED: To provide a method of manufacturing a negative electrode plate for nonaqueous electrolyte secondary battery in which cracking or interfacial fracture, due to expansion and contraction during charge and discharge, can be prevented while using a silicon-based or tin-based material.SOLUTION: A method of manufacturing a negative electrode plate for nonaqueous electrolyte secondary battery including a collector, and a negative electrode active material layer formed on at least a part of a surface of the collector includes: a coating step for coating at least a part of the surface of the collector with a composition forming the negative electrode active material layer containing negative electrode active material particles containing one kind or more selected from a group of silicon, a silicon alloy, silicon oxide, tin, a tin alloy, and tin oxide, a thermosetting resin, and hollow particles; and a heating step for heating the composition forming the negative electrode active material layer thus applied, at a temperature equal to or higher than the curing temperature of thermosetting resin contained in the composition forming the negative electrode active material layer, and a temperature equal to or higher than the pyrolysis temperature of hollow particles contained in the composition forming the negative electrode active material layer.
