SiO is a promising alternative to traditional graphite due to its high theoretical capacity, which can significantly increase battery energy density.
Key features of SiO-based batteries:
High capacity: SiO can provide higher specific capacity (up to 2,200 mAh/g) compared to graphite (370 mAh/g)
Volume expansion management: SiO undergoes less volume change than pure silicon, improving cycle stability
Potential for advanced energy storage: Ideal for applications demanding higher energy densities like electric vehicles and portable electronics
