ACC silicon-based and silicon-carbon anode materials mainly include: silicon oxide anode, pre-lithiated silicon oxide, silicon/graphite anode and silicon-carbon anode.

Silicon is one of the most prospective anode materials for lithium-ion batteries with the highest specific capacity (4200 mAh/g) discovered by mankind so far. However, it has low cycle life, high volume change, and persistent SEI film.

ACC silicon-carbon lithium-ion battery anode material adopts the emerging pre-lithiation technology, which can effectively improve these problems. It has a high lithium insertion potential, which prevents the formation and precipitation of lithium metal during the sintering process, and because the equilibrium potential is higher than the reduction potential of most electrolyte solvents, it does not form a passivation film with the electrolyte, at the solid-liquid interface, preventing many side reactions and greatly improving safety and stability. There is no need to add single-walled carbon nanotubes when the negative electrode of the cell is increased, which is cost-effective.
