Note:
Rechargeable Zn-air batteries have shown promising applicability as an advanced energy storage system to replace conventionally unsafe Li-ion batteries. Compared to Li-ion batteries, Zn-air batteries provide several advantages such as material availability, lower cost, environment friendliness, safety and comparably higher energy density. In this work, we propose to develop a novel design for stable and longer cycle-life Zn-anode by using scalable coating or surface treatment method, instead of conventionally used mercury, lead or cadmium based additives. We will study the electrode performance of surface modified Zn-metal anode. We will optimize the microstructure during cycling, which facilitates a consistent flow of Zn+ into and out of bulk Zn metal; and thus, a homogenous and stable Zn electro-deposition is realized with dendrite formations effectively suppressed. Therefore, the degree of Zn intercalation must be quantified to observe the microstructure change and its effects on Zn migration. The outcome of the study will be implemented in a large-scale Zn-ion battery cell development.
