The core technology of A 123

The core competitive advantage of A 123 is that the Ferrous lithium phosphate cathode material of lithium ion battery is made into uniform nano-sized ultrafine particles. Due to the sharp increase of particles and total surface area, the high discharge power of the battery is greatly increased, and the overall stability and cycle life are not affected. At present, the powder particles of general lithium ion cathode materials are about 0/00 times larger than A 123/KLOC-0. If it is made into small particles, it will weaken the stability and safety at the same time, so it will face the inherent limitation that it is difficult to improve the discharge power.

The main feature of lithium ferrous phosphate A 123 is nano-powder, and then the conductivity of the material is improved by the patented technology of doping high-valent metal ions. In the process of film making, the high current discharge capacity of the battery was greatly improved by corrosion and carbon coating on the surface of aluminum foil. In addition, the battery uses graphite with special material as the negative electrode, which greatly improves the rate performance and service life of lithium iron phosphate battery.

Power: the capacity density of high-energy products reaches140 w h/kg, the output density reaches 3000W/kg, and it can withstand high-power pulse discharge rate as high as 100C (current discharge of 0/00 times the nominal capacity);

The capacity density of high-power products reaches140 w h/kg, and the output density reaches 3000 W/kg.

Medium power products have higher performance and efficiency advantages;

Safety: it has been verified by many national laboratories and many automobile customers, and has strong abuse tolerance.

Cycle life: A 123 nano-phosphate technology provides excellent performance and cycle life. In the low interest rate cycle, it can provide thousands of cycles, and even in the discharge rate cycle of 10C, it can provide more than 1 000 complete cycles.
