Further, the paste can be used in place of paste paper to prevent the paste from falling off when filling the paste. The amount of positive electrode active material per cell was 25.0 g. The negative electrode active material wave is 20.
It is 5g. At this time, the weight ratio of the positive electrode active material to the negative electrode active material was 1:0.82. In addition, as a conventional example, a battery (conventional row 1) that does not use a carbon fiber nonwoven fabric and has the same amount of active material as the product of the present invention, and a positive electrode active material and a negative electrode active material that do not use a carbon fiber nonwoven fabric. A prototype battery (Conventional Example 2) with a weight ratio of 1:1.2 was fabricated.
