The Preparation Method of Stable Cycle of Silicon-based Lithium Ion Battery Anode by Compositing

Abstract

In order to overcome the difficulties in the development of high-performance lithium-ion batteries, a novel reparation method of stable cycle of Silicon-based Lithium ion battery anode by compositing is proposed in this paper. According to the characteristics of silicon element (SI), the preparation method considers that it has ultra-high storage capacity and is a high-quality anode material for battery. According to its limitation, that is, the volume expansion problem of the element in the process of using as the anode material for battery is analyzed. In addition, the kinky carbon sheet was studied, which can limit the volume expansion of silicon particles. Silicon and kinky carbon sheet were combined as raw materials for the preparation of battery. The results show that the battery has high reversible capacity and stable cycle performance, which not only reduces the cost of raw materials, but also saves time.
