Use in Lithium Batteries:

Nano-silicon has a high lithium absorption capacity, making it a promising material for enhancing the performance of lithium batteries. Its theoretical capacity can reach up to 4000 mAh/g, far exceeding that of traditional carbon-based materials. To address the issue of volume expansion during lithium ion intercalation, advanced technology is employed to coat nano-silica powder with graphite, forming a Si-C composite material. This coating not only reduces the expansion caused by lithium absorption but also improves the material’s interaction with electrolytes, promoting better dispersion and stability. As a result, the cycle life and overall performance of the battery are significantly enhanced. With continuous research and development, nano-silica is expected to play a key role in the future of high-performance energy storage solutions.
