Nano alumina for lithium battery
In the lithium-ion battery industry, nano-alumina is primarily used in separator coatings and electrode materials, where its performance directly impacts battery safety, cycle life, and energy density. KOSNANO’s nano-alumina meets four key performance criteria: physical properties, chemical purity, dispersibility, and safety. It performs particularly well in ceramic separator coatings, effectively preventing thermal shrinkage and internal short circuits, enhancing overall safety, and extending the cycle life of electrode coatings. KOSNANO’s technical team uses a low-sodium process combined with multi-stage pure water washing to control the sodium content below 20 ppm, ensuring it meets battery-grade standards. KOSNANO’s nano-alumina are widely applicable to the production of power batteries, energy storage batteries and consumer electronic batteries.

KOSNANO’s nano-alumina can not only be used as a coating material for electrodes and separators, effectively improving the thermal and electrical insulation of batteries, but can also deeply improve the core performance of batteries through various methods such as doping or coating. It can stabilize the lattice structure of lithium cobalt oxide, significantly improving the rate and cycle life; after coating, it can also inhibit side reactions, enhance thermal stability and overcharge resistance, and reduce capacity loss. At the same time, the doping of aluminum ions helps to increase voltage output; when used in spinel lithium manganese oxide materials, it can achieve excellent high-rate performance and cycle retention, making it an indispensable functional material in high-power lithium battery systems.
