概要（目的・用途・実施内容）/ Abstract (Aim, Use Applications and Contents)
Rechargeable zinc batteries have been attracting extensive attention as promising candidates for next-generation energy storage. Nevertheless, there are still several issues holding back the development of zinc batteries, such as poor cyclability. Herein this work, we aim to find the optimal additive that can improve Zn battery performance. SEM observation and Raman measurements were carried out for comparative studies regarding morphology and chemical state changes in Zn electrodes with additives.
実験 / Experimental
Firstly, Zn electrode samples were prepared by galvanostatic discharging with or without additives in our lab.
Then, SEM and Raman measurements were conducted to characterize morphology and chemical state changes in Zn electrodes.
結果と考察 / Results and Discussion
Fig. 1 depicts the SEM images of Zn electrodes after discharging with various concentration of additives. Morphology changes were clearly observed. Further, to figure out the underlying chemical state changes, Raman spectra were obtained, as shown in Fig 2. Accordingly, the relevance between ZnO crystallinity and morphoogy was confirmed.
