摘要：

A study was conducted to demonstrate the use of liquid-phase electrochemical scanning electron microscopy (EC-SEM) for in situ investigation of lithium dendrite growth and dissolution. A pair of Cu current collectors and Li electrodes was patterned on the top chip with a microgap lying in the middle of the viewing window. The two chips were sealed by epoxy, with a separation of approximately 0.5 mm. The orifices were also sealed with the same epoxy after the injection of the liquid electrolyte. During in situ electrochemical experiments, the growth and dissolution of lithium dendrites at the edges of the Li/Cu electrodes can be observed through the SiNx window by SEM.
