Hot Calending Laminating Machine For Dry Electrode Preparation
Introduction
The dry electrode process is a new manufacturing process for lithium-ion batteries, which does not use solvents in the electrode manufacturing process. Usually, the positive/negative active substances, conductive agents, and solid binders are directly mixed and sprayed onto the collector, or a self-supporting film is made through different processes and then compounded with the collector. This process does not use a large amount of organic solvents, which is beneficial for extending the capacity and cycle life of the battery.
Main machine composition
Heating and rolling laminating production line consists of 3 equipments:
1)Horizontal heating roller press machine ,
2)Vertical heating roller press machine,
3) Laminating heating roller press machine.
.The main machine is equipped with a heating control system, a roller gap adjustment mechanism, and corresponding feeding devices, pre heating devices, edge cutting devices, winding devices, adhesive coating devices, laminating devices, and tension detection devices The drive and tension control system, as well as the disassembly and assembly roller device, complete processes such as powder preheating, feeding, heating roller rolling, edge cutting, secondary hot roller pressing, gluing, lamination, and winding.
