LITHIUM SECONDARY BATTERY AND METHOD OF MANUFACTURING THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a lithium secondary battery whose performance of maintaining capacitance against repetition of charging and discharging is improved.SOLUTION: The lithium secondary battery includes a positive electrode, a negative electrode, and a nonaqueous electrolyte. On a surface of the negative electrode, cyclic siloxane and/or reaction product thereof exists. The cyclic siloxane is siloxy side chain containing cyclic siloxane having at least one dimethylsiloxy group at a side chain.
