Silicon oxide carbon
Category：
keyword：Experimental rotary kiln
Description
Silicon oxide carbon (SiOx-C) is a high-performance composite anode material for lithium-ion batteries, combining silicon oxide (SiOx, 0 < x < 2) with carbon matrixes (e.g., graphite, porous carbon, graphene). It leverages SiOx’s high theoretical capacity (~1600 mAh/g) for energy density enhancement while mitigating silicon’s severe volume expansion (~200-300%) via oxygen doping, which forms stable Si-O bonds and reduces structural strain.
The carbon component further improves electrical conductivity, inhibits particle agglomeration, and forms a protective SEI film. With balanced high capacity, good cycle stability, and moderate cost, SiOx-C is a key candidate for next-generation power batteries in EVs and energy storage systems, bridging the gap between traditional graphite and pure silicon anodes.
