Abstract

The invention discloses graphene coating aluminum foil coating device. The graphene coating aluminum foil coating device comprises a base, an aluminum foil roll wound on the base, a plurality of tensioning mechanisms, a sweeping mechanism, a stirring mechanism, a coating mechanism, a heating mechanism and a storage mechanism, wherein the aluminum foil roll comprises an aluminum foil base plate; the sweeping mechanism, the coating mechanism and the heating mechanism are sequentially arranged above the aluminum foil base plate at intervals in the walking direction of the free end of the aluminumfoil base plate; the stirring mechanism is distributed above the coating mechanism; the free end of the aluminum foil base plate enters the storage mechanism at a constant speed; the plurality of tensioning mechanisms are sequentially distributed between the aluminum foil roll and the sweeping mechanism, between the coating mechanism and the heating mechanism and between the heating mechanism andthe storage mechanism; and slurry stirred by the stirring mechanism can be evenly, continuously and quantitatively coated on the aluminum foil base plate, and the coating quality is very stable.

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to a graphene-coated aluminum foil coating equipment. Background technique [0002] As a high-capacity, long-life energy storage system, lithium secondary batteries have been widely used in small portable electronic products, and their application prospects in high-power power batteries and large-capacity energy storage batteries have attracted the attention of the world. gaze. The development of high-performance lithium-ion batteries is an important task in the field of electrochemical energy storage. In lithium secondary batteries, the active material is evenly coated on the surface of the current collector of aluminum foil or copper foil. The current collector collects and exports the electrons generated by the electrochemical reaction to the external circuit through physical contact with the active material, thereby realizing the conversion of chemical energy...
