LITHIUM SECONDARY BATTERY

摘要

PROBLEM TO BE SOLVED: To provide a lithium secondary battery in which reduction of a charge and discharge capacity is less, and which is superior in cycle characteristics.

SOLUTION: The lithium secondary battery 1 is adopted which is equipped with a positive electrode 2 containing a lithium containing complex oxide as the positive electrode active material, a negative electrode 3 containing graphite doped with lithium beforehand as the negative electrode active material, and a nonaqueous electrolyte, and in which the discharge terminal potential at the negative electrode is set at 0.5 V (to lithium) or less.
