Progress of Sacred Sun’s Lithium-ion Battery

• In view of the fierce competition of Lithium-ion battery in the communication market, reducing cost and lowering price is the only approach to consolidate and increase our market share. To achieve the objective of cost reduction and meanwhile improve the property of our Lithium-ion battery, we have made great achievements in the following aspects:

  1. Dry blending technology is applied in powder mixing process to shorten ingredients preparation time and improve the uniformity and adhesion of plates;

  2. Dispersion technology of pigment industry is brought in to achieve the molecular-level dispersion of paste;

  3. Roughen the surface of the aluminum foil (positive electrode) and copper foil (negative electrode) to improve the adhesion of paste and foils, and thereby prolong the service life of batteries;

  4. Adopt LiFePO4 made from iron oxide red craft instead of LiFePO4 made from iron oxalate to reduce cost;

  5. Adopt ovens with high vacuum degree to shorten the drying time of plates and meanwhile make sure the property of products.
