electromagnetic separator

The theoretical specific capacity of the silicon-carbon anode is up to 4200 mAh / g, which can increase the energy density of the battery by 20% -50%. This feature is critical to the range of electric vehicles (a 10% -24% increase) and the lightness of consumer electronic devices. The first effect is only 70% -85% (graphite> 90%), and the pre-lithium treatment is needed to supplement the lithium loss, pushing up the cost. The pre-lithium additive increases the cost by 30%. PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC Iron removal can improve the quality of the silicon-carbon anode.

PTMS Electromagnetic Separator

The expansion rate of silicon material is as high as 300%, and the mechanical structure of cylindrical cells can effectively buffer the volume changes, supporting a higher silicon addition ratio (5% -10%). High-embedded lithium potential avoids electrolyte decomposition, reduces SEI membrane generation, and reduces the risk of thermal runaway. The experiment showed that it can work stably at-50℃ ~80℃.Silicon reserves are rich and low price, PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC long-term cost of iron removal is lower than rare metal materials.

what is magnetic separation？

When charging and discharging, the expansion rate of silicon particles is 300% (graphite only 16%), resulting in the powder of electrode structure and the shedding of pole sheet, and the cycle life is generally 500-600 times (power battery needs 1000 times). Although alleviated by nanometer chemistry (<150nm), the yield of industrialization is still low. Mainstream process equipment input is high, mechanical alloying method is easy to introduce impurities, the solution method is complicated. Ionic method prepared nannanosilica powder PTMS LITHIUM COBALT ACID MATERIAL MAGNETIC.
