Application of silicon-based nanomaterials for improving the performance of battery

Abstract

This research discussed the improvement of using silicon-based nanomaterial in batteries compared to graphite batteries because not only in electric vehicles, but also mobile phone users are requiring for longer battery life and faster charging speed and phones cannot increase into an unacceptable weight. This research first introduces how lithium-ion batteries work and analyses the failure of lithium metallic battery: high cost and low security because of dendrites growth. Secondly, this paper discussed how mobile phone manufacturers improved their batteries by using silicon: Honors silicon carbon battery and Xiaomis silicon-oxygen anode battery. Both have increased the energy density and charging speed and lighter the weight at the same time. In general, silicon can improve battery performance through its high capacity for lithium-ion, and silicon can easily be found in a natural environment which will lead to lower manufacturing costs. As a result, this research can provide a new design approach for the structural design and application performance of nanomaterials in the field of battery applications.
