Abstract
Silicon, being the second most abundant element on the earth’s crust with the theoretical specific capacity of 4200 mAh g- 1, can serve as a cost-effective and environmentally benign anode material for next generation LIBs. The practical application of Si-based anode is, however, mostly hindered by its low electronic conductivity, colossal volume changes during lithiation/delithiation, and unstable nature of the SEI. Even though significant progress has been achieved in Si-based hybrid materials from the viewpoint of fundamental research, the commercial viability of Si-based anode demands low first cycle irreversible capacity loss, better capacity retention, good tap density, high Si content, simple and scalable manufacturing process, and most importantly low manufacturing cost. Additionally, an efficient, simple, low-cost, easily scalable synthesis methodology is desired which can assure an excellent electrochemical performance of Si-based anode materials. Herein, we have outlined the progress achieved in making a hybrid material with silicon as composite anodes, specifically carbon-silicon hybrid, oxide-silicon hybrid, silicon-metal hybrid, and silicide for LIBs. Further, this chapter covers several topics that pertain to practical considerations such as alternative and low-cost processing methods. The successful implementation of suitable alternative raw materials and processing methods are very essential for the production of Si-based anode, especially when approaching the industrial facility. © 2022 Elsevier Inc.
