Embodiment 1
[0051] A method for preparing a flexible battery pack, comprising the following steps:
[0052] (1) In an argon-protected glove box, use lithium cobaltate as the positive electrode active material, and use a coating machine to coat or spray the positive electrode sheet on aluminum foil, and use artificial graphite as the negative electrode active material, and use a coating machine to coat Cloth or spray on the copper foil to make the negative electrode sheet, the side coated with the positive electrode active material faces the separator, and the side coated with the negative electrode active material faces the separator, and the positive electrode sheet, separator and negative electrode sheet are wound or stacked Process to prepare winding core or stacked core. When winding and forming, the positive electrode sheet, separator and negative electrode sheet are stacked in sequence and then wound. The positive electrode sheet is in the inner layer and the negative electrode sheet...
