NONAQUEOUS ELECTROLYTE SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a nonaqueous electrolyte secondary battery capable of reflow soldering while preventing deterioration of battery characteristics during reflow.

SOLUTION: By using a positive electrode active material or a negative electrode active material comprising particles coated with an oil-repellent material, it is possible to manufacture the nonaqueous electrolyte secondary battery wherein high capacity reflow soldering can be attained.
