The invention provides tabletting equipment for lithium battery production and processing, and relates to the field of lithium battery production. The tabletting equipment for lithium battery production and processing comprises a shell; a container is arranged on one side in the shell, an unwinding wheel is arranged in the shell and is close to the container, and a winding wheel is arranged in theshell and is far away from the container; a guide wheel, a first pair of pressing wheels and a second pair of pressing wheels are sequentially arranged in the shell and located above the unwinding wheel and the winding wheel, a nozzle is arranged above the guide wheel, and electric heating nets and partition plates are arranged on the side wall of the shell and located on the two sides of the first pair of pressing wheels; a tensioning device is arranged on the side wall of the shell and located between the first pair of pressing wheels and the second pair of pressing wheels, a diaphragm is arranged on the unwinding wheel, and the other end of the diaphragm sequentially penetrates through the guide wheel, the first pair of pressing wheels and the second pair of pressing wheels and is fixed to the winding wheel. Through two times of drying and two times of rolling, the electrode material is uniformly distributed on the diaphragm.
Description
technical field [0001] The invention relates to the field of lithium battery production, in particular to tablet pressing equipment for lithium battery production and processing. Background technique [0002] Lithium batteries are a type of batteries that use lithium metal or lithium alloys as positive / negative electrode materials and use non-aqueous electrolyte solutions. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Li-ion batteries do not contain metallic lithium and are rechargeable. Lithium metal batteries, the fifth generation of rechargeable batteries, were born in 1996, and their safety, specific capacity, self-discharge rate and performance-price ratio are superior to lithium-ion batteries. [0003] In the production of existing lithium batteries, it is necessary to carry out a rolling operation on the electrode material sprayed on the separator, so that the electrode material is evenly distributed...
