Abstract

The invention is applicable to the field of batteries, and provides a method for manufacturing a polymer power battery and a polymer power battery manufactured by the method. The manufacturing method of the polymer power battery includes the following steps: rolling, packaging: packaging the rolling core in an aluminum-plastic film to form an electric core, and packaging a connecting tube and a vacuum tube on the aluminum-plastic film; baking, injecting liquid into: The liquid machine is connected with the connecting pipe, injecting liquid into the cell, and the vacuum machine is connected with the vacuum tube to control the vacuum degree in the aluminum-plastic film; then the electrodes are energized and activated; the battery is made. During liquid injection and formation, liquid can be injected into the battery core through the connecting pipe, and the vacuum tube can be connected with the vacuum pump to control the vacuum degree in the aluminum-plastic film and discharge the gas generated on the battery core in time, so as to improve the battery life. performance and safety; and airbags may not be provided or smaller airbags may be provided to reduce waste and cost, and batteries with larger capacity can be produced.

Description

technical field [0001] The invention belongs to the field of batteries, and in particular relates to a method for manufacturing a polymer power battery and a polymer power battery manufactured using the method. Background technique [0002] Polymer batteries generally use aluminum-plastic film to encapsulate the core structure. The production method of the polymer battery in the prior art is as follows: first batching ingredients, then making a winding core, and then sequentially encapsulating, baking, injecting liquid, pre-sealing, forming, secondary sealing, and separating the steps to form a polymer battery. When packaging, the core is generally packaged with aluminum-plastic film, and when packaging, not only the aluminum-plastic film must be packaged on the core, but also a section must be reserved on the side of the core, and sealed into a The airbag, so that in the subsequent liquid injection step, the battery can be injected by adding electrolyte to the airbag; afte...
