Over the last several decades, new battery technologies have been developed due to the need for consistently high energy density batteries. Lithium metal is the ideal cathode for next-generation lithium batteries, because it has a high specific capacity (3860 mAh g⁻¹) and the lowest reduction potential (−3.040 V vs. standard hydrogen electrode, SHE). However, safety issues caused by Li dendritic growth during Li plating interfere with the use of lithium metal-based rechargeable batteries. Li dendrites can cause dead lithium to accumulate on the lithium metal surface, resulting in increased resistance at the interface or short-circuiting, which can lead to explosion. Several studies have been proposed to inhibit the growth of lithium dendrites, such as electrolyte additives, surface coating, separator modification, and lithium metal host. In this experiment, Li was isolated by physically mixing Li and graphite to form a composite electrode, thereby suppressing Li dendrite growth. Li metal powder is synthesized by the droplet emulsion technique and this shape is prohibited dendrite growth. These Li metal powder+graphite composite anode was experimented with constant current charge/discharge tests and constant voltage tests. And the structure, morphology, and electrochemical properties of the new type of battery’s electrode were investigated by the implementation of X-ray diffraction (XRD), field emission scanning electron microscope (FE-SEM), and energy dispersive spectroscopy (EDS). The result was analyzed by electrochemical impedance spectroscopy (EIS).
