Problems solved by technology

However, in the existing coating process, some of the base materials of the pole pieces such as copper foil and aluminum foil have not been heat-treated, or the whole roll is used for heat treatment, but after the heat treatment, it still contains stress and is uneven, which affects The consistency of the product, the stress has a certain damage to the product structure, and the dense oxide layer cannot be formed on the surface of the aluminum foil after heat treatment, thus affecting the overall stability of the product

Abstract

The invention discloses a thin film base material processing system which comprises an unwinding module used for providing a thin film base material, a drying oven module used for heating the thin film base material, a strong oxidizing gas generator used for providing strong oxidizing gas and a winding module used for winding the treated thin film base material. The unwinding module is arranged on the base material feeding side of the drying oven module, the winding module is arranged on the base material discharging side of the drying oven module, a gas outlet of the strong oxidizing gas generator communicates with a heating cavity of the drying oven module, and a base material feeding port and a base material discharging port of the drying oven module are each provided with an air draft device. The thin film base material processing system can be used for unwinding and heating a film base material and also can be used for unwinding and heating some film base materials (such as aluminum foil) in a strong oxidation environment, so that moisture and stress can be removed, a compact oxidation layer can be formed on the surface of the film base material, a foundation is laid for a subsequent production process, the process is improved, and the overall stability of the product is improved.

Description

technical field [0001] The invention relates to the technical field of lithium battery production and processing equipment, in particular to a film substrate processing system. Background technique [0002] At present, the lithium battery industry at home and abroad has a good development prospect. Lithium-ion batteries have been widely used in portable electrical appliances such as laptop computers, cameras, and mobile communications due to their unique performance advantages. The currently developed high-capacity lithium-ion battery has been tested in electric vehicles and is expected to become one of the main power sources for electric vehicles in the 21st century, and will be more widely used in satellites, aerospace and energy storage. With the shortage of energy and the huge pressure on the world's environmental protection. Lithium batteries are now widely used in the electric vehicle industry, especially the emergence of high energy density material batteries, which ...
