The current production status of lithium manganese oxide positive electrode slurry for lithium batteries

Lithium manganese oxide is one of the most promising lithium-ion cathode materials. Compared with traditional cathode materials such as lithium cobalt oxide, lithium manganese oxide has the advantages of abundant resources, low cost, no pollution, good safety, and good rate performance, making it an ideal cathode material for power batteries. However, its poor cycling performance and electrochemical stability greatly limit its industrialization. Lithium manganese oxide mainly includes spinel type lithium manganese oxide and layered structure lithium manganese oxide. Among them, spinel type lithium manganese oxide has a stable structure and is easy to achieve industrial production. Nowadays, market products are all of this structure. Spinel type lithium manganese oxide belongs to the cubic crystal system, Fd3m space group, with a theoretical specific capacity of 148mAh/g. Due to its three-dimensional tunnel structure, lithium ions can be reversibly deintercalated from the spinel lattice without causing structural collapse, thus exhibiting excellent rate performance and stability.

At present, the positive electrode slurry of lithium manganese oxide batteries is generally ground and refined using a sand mill, which can reach 1-2 μ m. However, after grinding and refining with a sand mill, it is easy to experience agglomeration and form secondary aggregates. Difficulty in dispersion has also become a major challenge in the treatment of lithium battery slurries.


Application of SGN disperser in battery slurry

Lithium battery lithium manganese oxide disperser，Based on the analysis of multiple well-known lithium battery positive electrode material manufacturers, it can be concluded that if the slurry is finely ground in a sand mill and then dispersed by an SGN grinding and dispersing machine, the particle size of the slurry can be reduced, solving the problem of agglomeration. Using an SGN grinding and dispersing machine, the aggregates of lithium battery slurry are first opened, and then dispersed, zFinally obtaining high-quality lithium battery cathode slurry.

1、 Structure: SGN grinding and dispersing machine is a device that integrates colloid mill and dispersing machine, first grinding and then dispersing, especially suitable for the production and dispersion of lithium battery slurry. We will modify the three-stage high shear homogenizer emulsifier by replacing the three-stage with the first stage, and then adding a colloid grinding head on top of the emulsifier head, so that the material can be first finely ground by colloid before being dispersed, emulsified and homogenized by the emulsifier. The colloid mill can be replaced according to material requirements (we provide five types of emulsifying heads for customers to choose from, including 2P, 2G, 4M, 6F, 8SF, etc.)

2、 High shear force, SGN grinding and dispersing machine has a speed of up to 14000rpm, which makes material refinement more efficient and uniform. And the dispersion effect is better and the efficiency is faster.
