ELECTRICITY ACCUMULATOR DEVICE

摘要

Disclosed is an electricity accumulator device capable of being doped in the anode thereof with lithium in a short time, and of having resistance thereof minimized. An electricity accumulator device comprises a unit, wherein positive electrode sheets (9), each of which is provided with a cathode active material layer (1) and a cathode current collector body (4); and negative electrode sheets (10), each of which is provided with an anode active material layer (2) and an anode current collector body (5); are alternately layered with separators (3) interposed therebetween. Metal foil, etched metal foil, or porous lathed metal foil is used as the cathode current collector body (4) and the anode current collector body (5). Slits are cut in portions wherein the cathode active material layer (1) and the anode active material layer (2) are applied, and lithium supply sources are positioned in opposition to the negative electrode sheets (10) of the unit.
