Example 2 and comparative examples 1-3 were compared and based on comparative example 1. Comparative example 2 compared to comparative example 1, polyaspartic acid was added to the raw material of the negative electrode lead paste material. Comparative example 3 with respect to comparative example 1, modified graphene was added to the raw material of the negative electrode lead paste material.
