Abstract
Silicon (Si) is a promising candidate to replace graphite, the commonly used anode material for lithium-ion batteries. However, Si suffers from low electrical conductivity and large volume change during charge/discharge cycling. This research project investigated the fabrication of pure Si and Si-tin (Sn) thin-film anodes using physical vapour deposition. The project philosophy was based on employing a multifaceted approach to understand and optimise the performance of Si and Si-Sn anodes. This included studying the effect of residual film stress and deposition conditions on the electrochemical and cycling performance of Si anodes. In addition, the impact of electrolyte-additive and battery testing protocol was studied, which resulted in a high-capacity retention pure Si anode. Also, Si-Sn anodes proved to be promising candidates for high charge/discharge rate batteries.
