Title:
FLEXIBLE BATTERY
Document Type and Number:
WIPO Patent Application WO/2016/051645
Kind Code:
A1
Abstract:
The flexible battery comprises electrode lead terminals, an external cover body, and a sheet-shaped electrode group comprising a first electrode (2), a second electrode (3), and an electrolyte layer. The first electrode (2) and the second electrode (3) are rectangular, and one end of each of the electrode lead terminals is connected to a respective electrode on one side (S1t) of the electrode group. Each electrode comprises a collector and an active material layer, and a first active material layer (A1) on at least one of the main surfaces of the first electrode (2) has, on the S1t side, a non-opposing portion (Pt) which does not face the second active material layer (A2) on one of the main surfaces of the second electrode (3), and, over to the side opposite from S1t, a non-opposing portion (Pn) which does not face the second active material layer (A2) on the one of the main surfaces of the second electrode (3). In a leveled state, the shortest length (LAt) of the non-opposing portion (Pt) in the direction orthogonal to S1t and the shortest length (LAn) of the non-opposing portion (Pn) in the direction orthogonal to S1t satisfy LAt < LAn.
