Abstract

Abstract: TEM is one of the most powerful technologies for material research. In-situ TEM is a TEM technique that allows us to study samples in real-time. Researchers can focus on one area and change the conditions under the electron beam to acquire much more data from the material than conventional TEM techniques. In this research, we use the in-situ TEM technique to observe the rechargeable aqueous zinc-ion batteries which have been considered as a promising candidate for next-generation batteries. We established the platform for the aqueous battery system and studied the charge and discharge processes for both cathode and anode materials in rechargeable aqueous zinc-ion batteries for the first time. Besides, we also combined low-dose TEM techniques to observe the HRTEM images of the electrode materials to probe the change on the surface of the cathode materials and the mechanism of dendrite growth in rechargeable aqueous zinc-ion batteries.
