It was found that alloying Sn with some inert metallic components such as Ni, Cu, Co, can improve the cycling performance of Sn-based materials to a certain extent. Otherwise, both theoretical and experimental analysis proved that reducing particle size of Sn phase increases the active area, improves transport of electrolyte, and accelerates reaction rate. But aggregation of Nanoparticles usually deteriorates the electrode rapidly during charge-discharge cycling. Some researchers turn their attention to porous materials due to their large active area, more room for volume change, higher conductivity and no aggregation.
