Positive and negative material classification

 

Cathode: Lithium cobalt oxide, Lithium iron phosphate, Lithium manganese oxide, Ternary material (Lithium nickel cobalt manganese oxide)
Negative: Carbon (artificial graphite, natural graphite, mesocarbon microbeads), lithium titanate

 

Positive and negative materials process

 

Positive electrode: lithium cobalt oxide as an example; cobalt tetroxide, conductive agent (acetylene black), binder as raw material, crushing (jet mill) - the proportion of raw materials weighed (weighing meter) - mixing(Mixer)-sintering (sintering furnace) - crushing (jet mill) - screening (ultrasonic) - iron removal (PM) - packaging (During which include vacuum feeding or vibration feeding and dust removal equipment)
Negative: Take natural graphite as an example: Graphite - Crushing - Mixing - High Temperature Degreasing (Strip Furnace) - Chemical Purification - Drying - Sieving - Mixing - Coating Carbonization - Magnet(Magnetic Separator) - Sieving(Ultrasonic)-package

 

Problems encountered in screening

 

1. Production: Some factory because of process factors, poor material flow, high viscosity and low capacity;
2. Maintenance rate: from six months to one year, the ultrasound probe and the line and the power will appear maintenance point;
3. Screen Life: Some factory reflect the screen life is short;
4. Pollutants: iron and copper metal will pollute the raw materials, resulting in reduced battery capacity;
5. Over-size mesh: over the mesh aperture material appears in the down screen, increasing the probability of diaphragm damage.

 

Features

 

1. Production: Tianjin Bamo cobalt lithium test, the output of similar models of our company slightly higher than our peers;
2. Maintenance rate: Our ultrasonic probe is not easy to damage, the line have protection tube for secondary protection;
3. Screen Life: Mother-son ultrasonic frame can significantly improve the screen life;
4. Superfine material pass mesh: By reducing the ultrasonic vibration frequency and reducing the exciting force of the screen, the result is 7 times less than the conventional screen superfine material pass mesh;
5. After-sales service is guaranteed.
