Silicon (Si) is one of the most promising anode materials with the potential to meet the increasing demands of high energy and power for the next generation lithium-ion batteries. However, Si-based anodes suffer from huge capacity fading limiting their use in commercial applications. As one of root cause, it is known that Li⁺ ion diffusion is dramatically hindered leading to a strongly heterogeneous lithiation of the electrode and a rapid capacity fading after long term cycling. To break through the issue, we propose the Si_xFe_y/Li_1.3Al_0.3Ti_1.7(PO₄)₃ (SFLATP) Nanocomposite. In this study, we synthesized SFLATP Nanocomposite with high energy planetary ball milling. The SFLATP nanocomposite exhibited excellent cycle life, rate capability and coulombic efficiency demonstrating its potential to be readily transformable to commercial applications.
