The molecular-layer deposition of a flexible coating onto Si electrodes produces high-capacity Si nanocomposite anodes. Using a reaction cascade based on inorganic trimethylaluminum and organic glycerol precursors, conventional nano-Si electrodes undergo surface modifications, resulting in anodes that can be cycled over 100 times with capacities of nearly 900 mA h g(-1) and Coulombic efficiencies in excess of 99%.
在 Si 电极上沉积一层柔性涂层会产生高容量的 Si 纳米复合材料负极。使用基于无机三甲基铝和有机甘油前体的反应级联，传统的纳米-Si 电极进行表面改性，得到的负极可以循环 100 多次，容量接近 900 mA h g(-1)，库仑效率超过 99%。
