Abstract
Positive and negative active material particles 7a and 9a are adhered to the respective current collectors 6 and 8 by means of a binder resin 11 to prepare positive and negative electrodes 3 and 5. The positive and negative electrode active material layers 7 and 9 are adhered to a separator 4 with the binder resin 11 so that the interlaminar strength between each active material layer 7, 9 and the separator 4 may be not lower than that between the active material layer 7, 9 and the respective current collector 10, 9. A lithium ion-containing electrolytic solution is held in voids 12 made in the active material layers 7, 9 and the separator 4 to complete an electrical connection between the electrodes.
