Application of vacuum defoaming mixer in lithium battery slurry industry
Lithium battery cell slurry mixing is the mixing and dispersing process in the entire production process of lithium ion batteries, the quality impact of the product is greater than 30%, and it is the most important link in the entire production process.
Lithium ion battery electrode manufacturing, the positive slurry is composed of adhesive, conductive agent, positive electrode material, etc. The negative slurry is composed of adhesive, graphite carbon powder and so on. The preparation of positive and negative slurry includes a series of technological processes such as mixing, dissolving and dispersing between liquid and liquid, liquid and solid materials, and is accompanied by changes in temperature, viscosity and environment in this process. In the positive and negative slurry, the dispersion and uniformity of the granular active substance directly affect the movement of lithium ions between the two poles of the battery, so the mixing and dispersion of the slurry of each electrode material in the production of lithium-ion batteries is crucial, and the quality of the slurry dispersion directly affects the quality of the subsequent lithium-ion battery production and the performance of its products.
Vacuum defoaming mixer is a kind of basic material mixing equipment, using the centrifugal principle to stir, at the same time of high-speed rotation, with high power vacuum pump, can be in a few seconds to a few minutes to stir the material evenly and vacuum synchronous completion, to achieve the effect of removing bubbles. Equipped with different fixtures and cups, it is easy to meet all requirements from test to mass production. It can store 10 sets of data (can be customized), and each set of data can be divided into 5 sections to set different parameters such as time, speed, vacuum degree, etc., which can cope with the stirring defoaming requirements of most materials.
