Outline of Final Research Achievements

It is indispensable for the development of large scale advanced energy storage devices to control the surface nanostructures of the electrode during charging and discharging operations. In this work, analysis and modeling of the electrodeposition process were carried out from experimental and theoretical approaches to establish the precise methodology to analyze and control the process from single grain nucleation level. As for the electrode material for the large scale energy storage devices, potentiostatic electrodeposition of Zn electrode was conducted in aqueous alkaline solution, and the morphology evolution process, such as formation of mossy structures, is investigated in detail to elucidate its formation mechanism.
