What is the production process of lithium batteries?

The process technology of lithium-ion batteries is very strict and complex. We can only briefly present some of the main processes here. (1) Special solvents and binders are used for mixing sludge with powder positive and negative electrode active materials respectively, and after high-speed uniform mixing, sludge-type positive and negative electrode materials are made. (2) Coating film: Apply the prepared suspension evenly to the surface of the metal foil, dry it, and make positive and negative electrode plates respectively. (3) The assembly is placed in the order positive electrode sheet - separator - negative electrode sheet - separator from top to bottom, and is rolled to form the battery pole core. Then the battery is completed by electrolyte injection, sealing and others. process. The assembly process creates thethe battery is finished. (4) The chemical industry uses special battery charging and discharging equipment to carry out charging and discharging tests on finished batteries, inspect each battery, and select qualified finished batteries before leaving the factory.

Lithium battery assembly equipment

Generally used to measure the coating thickness of positive and negative electrodes of lithium batteries Laser thickness gauges can use Dacheng precision equipment and instruments. They are generally used to measure the thickness of positive and negative electrode coatings of lithium batteries and pressing of positive and negative electrode rolls of lithium batteries. The measuring principle is to use the laser triangulation distance measuring principle to measure the thickness of material of the film.
