Silicon (Si) has emerged as a potent anode material for lithium-ion batteries (LIBs), but faces challenges like low electrical conductivity and significant volume changes during lithiation/delithiation, leading to material pulverization and capacity degradation.
By balancing the other components in the cell, it is realistic to increase the overall capacity of the battery by 100%–200%. However, the exploitation of silicon in LIBs is anything else than a simple task due to the severe material-related challenges caused by lithiation/delithiation during battery cycling.
Carbon appears to be an indispensable component of anode for lithium ion battery. To make Si nanoparticle as a practical anode, silicon and carbon based composite would be the ideal route.
Some commercial battery makers, including Tesla, have boosted the lithium-holding capacity of their batteries’ anodes by adding a small amount (usually up to 5 percent) of silicon. But silicon anode startups want to go much further. Most of them are looking at nano-engineered silicon as a workaround to the swelling and side-reaction problems.
To address the chemi-mechanical effect of Si based materials as anode for lithium ion battery, innovative nanostructure designing concepts have been emerged over the last few years. These nanostructural designing concepts set the foundation for optimized tailoring Si based material as high capacity anode for lithium ion battery.
Over the past decade, researchers have explored various ways to improve the performance of silicon as the anode material, one of which is designing nanosized Si anode materials to enhance their lithium storage performance.
