Flexible battery and preparation method thereof

[0034] An embodiment of the method for preparing a flexible battery provided by the present invention, the method for preparing a flexible battery proposed by an embodiment of the present invention includes:

[0035] A flexible frame is arranged around the pole group fixing area on the inner surface of the first flexible film layer;

[0036] Among them, the pole group fixing area is used to set the battery pole group, the battery pole group includes a body part and an electrical connection terminal part, and the electrical connection terminal part is used as the power supply output end of the body part, usually a battery tab, and the battery tab includes a positive pole ear and negative ear.

[0037] disposing the body part of the battery pole group in the flexible frame;

[0038] The inner surface of the second flexible film layer is opposite to the inner surface of the first flexible film layer, and sealed to form a flexible wrapping film, so that the flexible wrapping film wr

[0045] The hot-melt temperature of the hot-melt adhesive is 165°C, the glue-out speed of the hot-melt adhesive is 100mm / s, the dispensing speed of the hot-melt adhesive is 400mm / s, and the hot-melt adhesive The dispensing thickness is 2mm. The test measures the peel strength between the flexible frame body and the inner surface of the first flexible film layer at 10N / in.

[0047]The hot-melt temperature of the hot-melt adhesive is 170°C, the glue-out speed of the hot-melt adhesive is 100mm / s, the dispensing speed of the hot-melt adhesive is 400mm / s, and the hot-melt adhesive The dispensing thickness is 2mm. The test measures the peel strength between the flexible frame body and the inner surface of the first flexible film layer at 15N / in.
