WIPO Patent Application WO/2017/068706

Kind Code:

A1

Abstract:

[Problem] To provide a battery pack capable of decreasing device size. [Solution] A battery pack 100 that has a battery group 100G, a busbar 131, and terminal members (anode-side terminal 133 and cathode-side terminal 134). The battery group is obtained by layering a plurality of single cells 110 in the thickness direction thereof that are each provided with a battery body 110H containing a power-generating element 111 and formed so as to be flat, and also provided with an electrode tab 113 derived from the battery body, wherein the electrode tabs align with one another in the layering direction. The busbar is plate-shaped, is joined to the electrode tabs of the single cells, and electrically connects the electrode tabs of at least two single cells with one another. The terminal members are joined to the busbar, and relay the input and output of power in the battery group. Furthermore, the battery pack is configured in a manner such that when seen from a direction perpendicular to the plane along which the electrode tabs of the battery group align, the terminal-joining position on said plane where the terminal members are joined to the busbar is separated from the position thereon where the busbar and the electrode tabs are joined to one another.
