PARÂMETROS DO PRODUTO
Descrição
This type of silicon-carbon anode material, through a composite design of a high-capacity silicon phase and a stable carbon-based framework, significantly improves energy density while effectively mitigating the volume expansion problem of silicon during charge and discharge, thus maintaining excellent structural stability and cycle life.
The product exhibits good interfacial compatibility and electrochemical stability, and can be widely adapted to solid-state, estado semi-sólido, and liquid battery systems. It meets the comprehensive requirements of next-generation high-energy-density batteries in terms of safety, lifespan, and performance consistency, making it an ideal anode solution for high-end power batteries and advanced energy storage technologies.
