    Scalable synthesis of innovative silicon/carbon nanocomposite for next generation lithium-ion battery anodes
    (University of the Western Cape, 2022) Larkin, Roy-John; Ross, Natasha
    Silicon is the most promising lithium-ion battery (LIB) anode due to its ultra-high capacity (4200 mAh/g), which is 10 times greater than commercially available graphite anodes (372 mAh/g). Utilizing this large capacity allows for the development of high-performance LIBs for next generation innovative applications. However, during lithiation/delithiation, silicon anodes experience a volume change of over 300% which leads to mechanical and electrochemical degradation that limits cycle efficiency and life span. To remedy this limitation, porous silicon nanoparticles were composited with CNTs - as it produces mechanically stable architectures capable of buffering large volume changes.
