The lithium battery slurry fixed-depth and quantitative sampler is simple in structure and accurate in measuring result, and production efficiency is improved greatly.

Description

technical field [0001] The invention belongs to the field of material preparation, in particular to a depth-fixed and quantitative sampler for lithium battery slurry. Background technique [0002] With the development of modern industry, lithium batteries have been widely used in people's daily life and work. The mixing and dispersing process of lithium battery cell slurry has an impact on product quality of more than 30% in the entire production process of lithium ion batteries, and is the most important link in the entire production process. The preparation of the current lithium-ion battery slurry is completed in the dual-planet dispersion equipment. Although the production technology of small batteries has become increasingly mature, the consistency control of batteries is still a technical difficulty in the production of lithium-ion batteries, especially for large-capacity and high-power power lithium-ion batteries. Battery. In addition, with the continuous progress ...
