PURPOSE:To provide a nonaqueous electrolytic secondary battery with long cycle life and high discharge capacity by using a carbide of specific polyamidetriazole as a negative electrode of a nonaqueous electrolytic secondary battery. CONSTITUTION:In a nonaqueous electrolytic secondary battery 10 with a positive electrode 1 containing lithium, a negative electrode 2, and a nonaqueous electrolytic, a carbide prepared by carbonizing polyamidetriazole represented by the formula (1<=X<=4, n is an integer of 1 or more) is used in the negative electrode 2. The condition of carbonization is not especially limited. For example, carbonization is conducted in N2 flow, at a temperature rising speed of 1-20 deg.C/min., and at a maximum temperature of 700-1500 deg.C. |
