550540 low cobalt single crystal ternary material for power battery
Sample name | Charging capacity | 0.2C | First effect | 0.33C | 0.5C | 1C | 0.2C | 1C | 50cycle conservation rate |
550540 monocrystal | 200.1 | 168.8 | 84.35% | 168.2 | 165.1 | 158.2 | 171.5 | 158.5 | 100.44% |
●At present, this material is the main battery material in Contemporary Amperex Technology Co., Limited, and there is no second one in China. The ternary material with low cobalt has very strict requirements on the process, but it has great advantages in cost and safety.
●The high-temperature sintering time is 8 hours, which is far lower than the current 12-hour sintering process of other manufacturers, and has the dual advantages of high yield and low production cost.
651520 single crystal ternary material for power battery
●This material is the main material for high-performance power batteries.
●It has the advantages of high productivity and low production cost, and the pilot test has been completed.
712 single crystal ternary material for power battery
Sample name | Charging capacity | 0.2C | First effect | 0.33C | 0.5C | 1C | 0.2C | 1C | 50cycle conservation rate |
