This product adopts in-situ surface coating technology to form a uniform nano alumina coating on the surface of lithium carbonate particles, effectively blocking the side reaction between electrolyte and cathode materials, improving the thermal stability of the battery and avoiding the risk of thermal runaway at high temperatures. At the same time, it optimizes the particle interface performance, improving the compaction density of lithium iron phosphate cathode materials and reducing the internal resistance of the battery, solving the pain points of short cycle life and poor fast charging performance of traditional energy storage batteries.
Purity ≥99.95%, alumina coating content 1.0±0.2%, sodium (Na) ≤3ppm, iron (Fe) ≤1ppm, moisture ≤0.03%, particle size D50=18μm, thermal decomposition temperature ≥200℃, packaged in 25Kilograms sealed steel drums, complies with UN 3077 transportation standards. Customizable coating ratio and particle size parameters are available according to customer needs.
Mainly used for the modification of cathode materials for lithium iron phosphate energy storage batteries, adapting to scenarios such as household energy storage systems, commercial and industrial energy storage power stations, and grid peak shaving projects. It can increase the cycle life of energy storage batteries from 2000 times to more than 2300 times, while improving the fast charging performance of the battery, adapting to energy storage needs in 70% fast charging scenarios, and meeting the raw material standards of energy storage battery manufacturers such as CATL and BYD.
