Chemical prelithiation of SiOx/Gr anode for improved cycling performance in lithium-ion batteries

Abstract

Owing to its high specific capacity and excellent cycling performance, SiOx is an appealing alternative to traditional graphite anodes. In order to increase the anode's cycling stability, this work demonstrates the chemical prelithiation of SiOx/Gr anode for real-world applications. The highest ICE obtained is 98.8 % using the chemical prelithiation method for half cell. The prelithiated anode was characterized using various techniques, and the viability of the process was tested using a pouch cell assembly, demonstrating enhanced capacity compared to the pristine pouch cell. This research has implications for portable electronics, electric vehicles, renewable energy storage, and other applications requiring high-capacity and long-lasting batteries.
