Lithium battery electrode plate impressing device

The invention belongs to the technical field of lithium battery element preparation, and particularly relates to a lithium battery electrode plate impressing device which comprises a feeding belt, an auxiliary material belt, a slitting assembly and an impressing assembly. In the actual operation process of the lithium battery, waste of electrode plate materials and active substance coating materials is caused on an electrode plate of a part where a circuit terminal is not in direct contact, and meanwhile, the utilization rate of the working efficiency of an imprinting device is also weakened; therefore, the raw material of the current collector of the electrode slice is conveyed to the cutting plate through the feeding belt to be cut and processed into the shape only in electrical contact with the circuit terminal, the size of the current collector material of the electrode slice entering the imprinting assembly is reduced, the resistance borne by the pressure head when the pressure head feeds the current col
