Stirring method of ceramic slurry

Abstract

The invention provides a stirring method of ceramic slurry and relates to the technical field of slurry preparation. The stirring method of the ceramic slurry comprises the following steps in sequence: mixing powder materials, adding glue and mixing, adding a solvent and mixing and the like. By adopting the stirring method provided by the invention, the technical problems in the prior art that thesolvent and the glue are added and stirred in a stirring machine, then the powder materials are added into a high-speed dispersion machine and are subjected to high-speed dispersion, high molecular substances in the glue cover the surfaces of the agglomerated powder materials, the stability of slurry is poor and a coating is not uniform when a lithium battery is coated with the slurry are solved.According to the stirring method provided by the invention, the coverage of the high molecular substances in the glue is not carried out in a dispersion process, so that the dispersion of the powdermaterials is stopped and the dispersion efficiency can be remarkably improved; the lithium battery is coated with the slurry so that the density of a coating surface formed in a coating process is uniform; in a charging and discharging process of the lithium battery, the coating on each position of the lithium battery has the same blocking effect, so that the consistency of internal resistance isimproved.

Description

technical field [0001] The invention relates to the technical field of slurry preparation, in particular to a stirring method for ceramic slurry. Background technique [0002] Lithium battery is a type of battery that uses lithium metal or lithium alloy as the negative electrode material and is welded with non-aqueous electrolyte. Lithium batteries can be roughly divided into: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable; lithium metal batteries are superior to lithium-ion batteries in terms of safety, specific capacity, self-discharge rate, and cost performance. Therefore, lithium batteries are widely used in energy storage power systems such as water power, fire power, wind power and solar power stations, uninterruptible power supplies for post and telecommunications, as well as power tools, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace and many oth...

Problems solved by technology

[0006] The purpose of the present invention is to provide a stirring method for ceramic slurry, to solve the problems existing in the prior art, first add solvent and glue to stir in the mixer, then add powder to carry out high-speed dispersion in the high-speed disperser, using the mixer and With the combination of high-speed dispersing machine, the high-molecular substances in the glue will be wrapped on the surface of the powder agglomeration, and the stability of the slurry is poor. The coating of this slurry on the lithium battery is likely to cause uneven coating and affect the electrolyte in the electrolyte. The uniformity of lithium ion transmission leads to the technical problem of discrete battery internal resistance
