Silicon-carbon (Si/C) composite anodes represent a significant advancement in battery technology, particularly for lithium-ion batteries. These materials leverage the high theoretical capacity of silicon (~4200 mAh/g) while addressing its challenges, such as significant volume expansion during charge and discharge cycles, by integrating carbon.
The CVD process for depositing carbon on silicon anodes involves the introduction of organic gas into the pores of porous carbon particles, followed by high-temperature pyrolysis to deposit silicon nanoparticles.
