Abstract

The invention provides a winding and unwinding system, a control method, a control unit and a computer storage medium. The winding and unwinding system comprises a winding and unwinding box, a cooling unit and a control unit, the winding and unwinding box comprises a box body, a box door, a pole piece discharging port, a rotating shaft, a pole piece cylinder and a first temperature sensor, wherein the box body and the box door jointly limit a box space of the winding and unwinding box; the pole piece discharging port is formed in the side face of the box body; the rotating shaft is arranged in the middle of the box space; the first gas detector is used for monitoring the oxygen concentration in the winding and unwinding box, the gas inlet is formed in the lower portion of the box body, the gas outlet is formed in the upper portion of the box body, the cooling unit is communicated with the gas inlet, and the control unit controls the cooling unit to adjust the temperature of the pole piece and the oxygen concentration in the winding and unwinding box according to the temperature of the pole piece and the oxygen concentration in the winding and unwinding box. Pole piece quality is guaranteed and potential safety hazards are reduced.

Description

technical field [0001] The present application relates to the field of battery technology, and in particular, to a winding and unwinding system for pole pieces, a control method for pole pieces, a control unit, and a computer storage medium. Background technique [0002] With the rapid development of clean energy and the country's policy support for the field of new energy vehicles, lithium batteries with high voltage, high energy density and long cycle life have attracted much attention. Since the formation of the solid electrolyte interface (SEI, Solid Electrolyte Interface) film inside the lithium battery loses part of the lithium ions, at present, the pole piece lithium replenishment technology that supplements lithium ions from the outside is preferred. [0003] However, the pole piece after lithium supplementation needs to be wound or unwinded. During the winding or unwinding process of the pole piece, the supplemented lithium easily reacts with air. This reaction gen...
