Embodiment Construction

[0035] The present invention will be further described below in conjunction with the accompanying drawings.

[0036] A templated manufacturing method for a single-sided laminated pouch battery, comprising the following steps:

[0037] First, make the diaphragm, positive electrode sheet and negative electrode sheet according to the preset standard size, refer to the conventional positive electrode sheet and negative electrode sheet production method, the steps are as follows:

[0038] Step 1) Dry lithium iron phosphate (LFP), graphite and carbon black conductive agent (SP) powders in an oven at 90°C for more than 24 hours for later use. The conductive agent powder needs to be ground for about 10 minutes to ensure the dispersion effect.

[0039] Step 2) The LFP, graphite and respective conductive agents obtained in step 1) are mixed in a certain proportion, N-methylpyrrolidone (NMP) is used for the positive electrode dispersant, and carboxymethyl cellulose (CMC) is used for the ...

Abstract

The invention relates to the field of testing and verification of lithium-ion battery materials, and in particular to a template-based manufacturing method for single-sided laminated pouch batteries. The method assembles positive electrodes, negative electrodes, and separators of fixed standard sizes under a specially designed template. Then it is packaged with aluminum-plastic film. Compared with traditional manual assembly, it can greatly improve the assembly efficiency and consistency of single-sided laminated soft-pack batteries, and overcome the manufacturing defects of single-sided laminated soft-pack batteries. The single-sided laminated pouch battery has inherent characteristics such as simple manufacture and a greater degree of simulation of the working state of the full battery, which can save experimental resources to a greater extent and improve the efficiency of verification materials.

Description

technical field [0001] The invention relates to the field of testing and verification of lithium-ion battery materials, in particular to a template-based manufacturing method for a single-sided laminated pouch battery. Background technique [0002] Lithium chemical power supply is a device that converts chemical energy into electrical energy, such as lead-acid batteries. Its invention and application have laid the foundation for the development of storage batteries. As the fastest and best lithium-ion battery system among them, people have been looking for open up new directions. As an energy device and energy storage method, secondary batteries play an important role in the development and utilization of new energy, among which lithium-ion batteries have been widely used due to their excellent performance. [0003] As a direct factor affecting battery performance, materials are very important to verify at the cell end. At present, there are two methods for verifying the e...
