Advancements of Applying Nano-Structured Silicon Anode for Next-Generation Energy Storage

Abstract

In the advancement of modern technology, lots of innovations have been introduced to civil engineering, transportation and energy systems. Among them, nanotechnology stands out as a pivot with wide-ranging potential. Especially in EVs, nanotechnology involves in improving battery performance. For instance, extending the cycle life, providing faster charging speed, and increasing energy density. Silicon anode gives larger energy capacity which is a good attempt for more efficient lithium-ion batteries. However, the large volumetric change of silicon making this approach unapplicable. Nano-structured silicon and Si/C composites have been proven to have the ability to release the cracking stress through its small size and carbon shell respectively, this offers the opportunity for the further investigation of development of nano-silicon anode. However, many concerns for mass production and manufactural safety have been developed. These problems can be overcome by further research for more safer and cheaper mechanism and machines, proper regulation and sensitive triggers during manufacturing process could avoid the majority of safety issues.
