| 摘要 |
The present invention relates to a stack battery structure, which possesses a high energy density and can avoid the existence of a die volume. Through the means of separating binder and active materials and of rearranging the position of binder, the positive/negative electrode thus fabricated can be glued with a polymeric separator membrane via the binder in the stacking and pressuring process without affecting the percentage of active materials in each unit of weight. This stack battery structure obviates the problem of a die volume caused by rolling the cell electrode into a spiral in the prior art. It also increases the energy density of the battery.
