Title:
SINGLE-SIDED PRINTING LAMINATED BATTERY AND PRINTED BATTERY PACK
Document Type and Number:
WIPO Patent Application WO/2022/156358
Kind Code:
A1
Abstract:
A single-sided printing laminated battery and a printed battery pack, sequentially comprising, from bottom to top, a substrate, a lower electrode layer, and a unit layer. The unit layer sequentially comprises, from bottom to top, an insulation layer and an upper electrode layer; the upper electrode layer is electrically connected to an upper lug; the lower electrode layer is electrically connected to a lower lug; the upper lug and the lower lug are printed on the substrate; and the upper lug and the lower lug are insulated from each other. In the present invention, by laminating positive and negative electrodes of the single-sided printing laminated battery, and using the insulation layer to isolate same, single-sided arrangement of the positive and negative electrodes is implemented, such that the battery in the present invention can be directly printed on the corresponding substrate to implement integration with an electrical appliance; and fastness of the connection between the battery and the electrical appliance and production efficiency are ensured. In addition, compared with the battery of a common coplanar structure, the single-sided printing laminated battery of the present invention has a larger effective active area of the electrode in the same projection area, and therefore, a theoretical capacity of the battery is also larger.
