Abstract

The invention belongs to the technical field of batteries, and discloses a preparation method and application of a lithium cobalt oxide soft-pack battery. The preparation method comprises the following steps: preparation of a lithium cobalt oxide positive electrode; preparation of a graphite negative electrode; preparation of an aluminum plastic film; screening and tab welding the positive and negative electrode, then winding core and packing, injecting an electrolyte to a resulting pack, perform first sealing, formation, second sealing; followed by capacity grading to obtain the lithium cobalt oxide soft pack battery. The preparation method for the lithium cobalt oxide soft-pack battery in a laboratory environment at room temperature provided by the present invention has simple operation and low environmental requirements, can be used in laboratories without dry room conditions, and reduces research and development cost and laboratory maintenance cost.
