The zinc deposition reaction onto metallic zinc has been investigated at the single particle level through the electrode-particle collision method in neutral solutions, and in respect of its dependence on the applied potential and the ionic strength of a sulphate-containing solution. Depending on the concentration of sulphate ions in solution, different amounts of metallic zinc were deposited on the single Zn nanoparticles. Specifically, insights into the electron transfer kinetics at the single particles were obtained, indicating an electrically early reactant-like transition state, which is consistent with the rate-determining partial de-hydration/de-complexation process. Such information on the reaction kinetics at the nanoscale is of vital importance for the development of more efficient and long-lasting nanostructured Zn-based negative electrodes for Zn-ion battery applications.

已经通过在中性溶液中通过电极-颗粒碰撞法在单个颗粒水平上研究了锌在金属锌上的沉积反应，并且考察了其对所施加的电势和含硫酸盐溶液的离子强度的依赖性。根据溶液中硫酸根离子的浓度，不同数量的金属锌沉积在单个Zn纳米颗粒上。具体而言，获得了对单个粒子上电子转移动力学的见解，表明了电早期的类似反应物的过渡态，这与决定速率的部分脱水/解络过程一致。
