LITHIUM SECONDARY BATTERY

摘要

PURPOSE:To obtain the energy density in high degree and the superior cycle characteristic by using a negative electrode body which is formed by doping the carbon black having the specific characteristics, with lithium efficiently and in stable manner. CONSTITUTION:A negative electrode body is formed by allowing the carbon black having an arithmetic average primary particle diameter of 70nm or less and the dimension Lc (002) of the crystal element in the c-axis direction of 10nm or more to be loaded with metal lithium as negative electrode activating substance.
