Abstract
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.
