With the rapid development of electronic devices and energy electric vehicles, there is an increasing demand for safe, energy-dense batteries. (1−6) However, lithium-ion batteries, which are widely used at present, have the disadvantage of low energy density; (7) the lithium metal anode exhibits a high theoretical capacity of 3860 mAh g–1 and the lowest reduction potential (−3.045 V versus standard hydrogen electrode).
