Electrodeposited Growth Habit and Growth Mechanism of ZnO as Anode Material of Secondary Alkaline Zn Battery

The process of morphology evolution of nanorod, nanoparticle, and conventional as anode materials of secondary Zn battery on the charge-discharge cycling were investigated. with different morphology and particle size showed different electrodeposited growth habit, including the morphology retention on the initial stage and the formation of lamellar on the subsequent stage, which resulted in the different electrochemical performance of . The material utilization of nanorod and nanoparticle surpassed the conventional . Epitaxial growth and texture growth were proposed to illuminate the electrodeposited growth habit of . The epitaxial growth resulted from the influence of the substrate and led to the morphology retention of nanorod and nanoparticle. The texture growth was mainly influenced by the crystal structure, substrate, current density, etc., including the lateral and outward growth models. The Zn dendrites were the results of preferential growth of some lamellar , associated with the orientation and the surface protrusion of the lamellar .
