Stacked battery

1. A stacked battery comprising:

a stacked body formed by alternately laying plate-shape positive electrodes and plate-shape negative electrodes one on the other by way of separators;

each of the positive electrodes and the negative electrodes having recessed sections and corresponding projecting sections on a battery active surface thereof;

the recessed sections of each electrode being disposed in the projecting sections of one of the adjacent electrodes of the opposite polarity by way of a separator, except those arranged closest to the exposed surfaces of the stacked battery, and the projecting sections of each electrode being disposed in the recessed sections of the other adjacent electrode of the opposite polarity by way of a separator; and

holding members respectively engaged directly or through at least either a separator and a film casing with the recessed sections and the projecting sections of the electrodes arranged closest to the exposed surfaces;

the holding members being formed as rod-shaped members or plate-shaped members and rigidly secured to the film casing covering the stacked body and sealing the stacked body;

the positive electrodes and the negative electrodes being respectively connected to a positive terminal and a negative terminal.

2. The stacked battery according to claim 1 , wherein

the holding members have a profile that makes the holding members snugly engaged with the recessed sections or the projecting sections.

3. The stacked battery according to claim 1 or 2 , wherein

the holding members are arranged inside the film casing and pressed by the film casing due to the pressure difference acting on the inner and outer surfaces of the film casing.

4. The stacked battery according to claim 1 or 2 , wherein

the holding members are arranged outside the film casing and secured to the film casing by an adhesive agent, adhesive tapes or removable securing means.

5. The stacked battery according to claim 1 , wherein

the recessed sections and the projecting sections comprises at least one groove-type selected from a v-shaped, a semicircular, a corrugated cross section, a semispherical, a frusto-conical profile or a combination thereof.

6. The stacked battery according to claim 1 , wherein

the holding members extends to cover the entire positive electrodes.

7. The stacked battery according to claim 1 , wherein

the holding members extends to cover the entire negative electrodes of the stacked battery.

8. The stacked battery according to claim 1 , wherein

the holding members comprise a metal.

9. The stacked battery according to claim 1 , wherein

the positive electrode comprises a complex oxide.

10. The stacked battery according to claim 9 , wherein

the complex oxide is at least one of lithium-manganese complex oxide, lithium-cobalt complex oxide and lithium-nickel complex oxide.

11. A stacked battery according to claim 1 , wherein

the holding members are formed as rod-shaped members.

12. A stacked battery according to claim 1 , wherein the holding members are formed as plate-shaped members.
