On April 23, 2019, Qiaobao Zhang at Xiamen University was invited to visit ERCN, giving the lecture entitled “Design, performance regulation and mechanism study by in-situ electron microscopy of lithium-ion battery conversion/alloy reaction anode”. According to using of in-situ TEM, Prof. Zhang’s lecture mainly focused on the design of the electrodes structure as well as electrochemical behavior of composite anode during lithium insertion/extraction. Besides, Prof. Zhang introduced the latest considerable research progress of his research group.
