Problems solved by technology

[0003] During the production of lithium batteries, the slurry of lithium batteries needs to be coated to form pole pieces, and then the pole pieces are cold-pressed by pressing rollers to form a specified thickness; and the current cold-press devices are all disposable and direct Roll forming is easy to cause deformation of the pole piece, and the thickness of the roll cannot be adjusted accurately. At the same time, after cold pressing, the surface flatness is low, which reduces the product quality

Description

technical field [0001] The invention relates to the technical field of lithium battery production, in particular to an anti-deformation cold pressing device for lithium battery production. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and uses non-aqueous electrolyte solution; due to the very active chemical properties of lithium metal, the processing, storage, and use of lithium metal have very high environmental requirements; therefore, Lithium batteries have not been used for a long time; with the development of science and technology, the above problems have been gradually overcome, and lithium batteries have become the mainstream at present. [0003] During the production of lithium batteries, the slurry of lithium batteries needs to be coated to form pole pieces, and then the pole pieces are cold-pressed by pressing rollers to form a specified thickness; and the current col...
