Abstract

A combined battery (100) comprising a plurality of flat-type cells (10A to 10F) by laminating thereof so that polarity of electrode tabs (11A to 11F and 12A to 12F) is alternately set, wherein welding parts to connect in series the flat cells themselves, to compose a set when all the flat-type cells (10A to 10F) are laminated, are separated at a plurality of positions of the combined battery, and the flat-type cells having such a structure that all the flat-type cells are electrically connected in series by welding each of the welding parts.

Claims2

Dependent claims

A combined battery, comprising:

at least three flat-type cells each having electrode tabs with different polarities, wherein the flat-type cells have two major surfaces and a thickness,
wherein the flat-type cells are laminated by stacking the flat-type cells in a lamination direction substantially perpendicular to the major surfaces and two flat-type cells are selectively and electrically connected to one another via a welding part connecting electrode tabs of the two flat-type cells,
wherein all electrode tabs of a third flat-type cell, which is laminated next to the two flat-type cells connected via the welding part, are offset from the portions of the electrode tabs of the two flat-type cells electrically connected to one another via the welding part, when viewed along the lamination direction.

Dependencies are inferred from the claim text.
