Abstract

This utility model belongs to the field of battery technology and discloses an all-solid-state transfer thermal composite stacking device, including an electrolyte transfer module, a thermal composite module, a cutting module, and a stacking module. The electrolyte transfer module includes a first unwinding roller, a second unwinding roller, a transfer roller, and a take-up roller. The first unwinding roller and the take-up roller are arranged in a one-to-one correspondence to connect the electrolyte on the electrolyte base film with the negative electrode sheet to form a first composite electrode sheet. The thermal composite module includes a third unwinding roller and a pressure roller. The pressure roller is located downstream of the transfer roller and is used to connect the positive electrode sheet with the first composite electrode sheet to form a second composite electrode sheet. At least two sets of pressure rollers are arranged. The cutting module is located downstream of the thermal composite module. The stacking module is located downstream of the cutting module. In this way, by integrating the electrolyte transfer module, thermal composite module, cutting module, and stacking module, continuous preparation of electrode units can be achieved, and the isostatic pressing process can be eliminated, reducing the production cost of solid-state batteries and improving production efficiency.
