Background Although lithium-ion batteries have been researched for more than three decades, their limited energy density still cannot meet the range anxiety of current electric vehicles to some extent. Therefore, developing safe, reliable, low-cost, and high-energy density batteries has become a priority. Among them, the theoretical capacity of lithium metal anodes is as high as 3860.0 mAh/g, and the redox potential is as low as −3.040 V (vs. standard hydrogen electrode, SHE), which has attracted much attention from researchers and enterprises. However, lithium metal anodes still face many challenges in practical applications, such as uneven lithium deposition, unstable solid electrolyte interface (SEI), and constant volume changes during cycling. In order to solve the above problems, researchers have developed various methods, such as introducing 3D host materials, constructing artificial solid electrode interfaces, and designing solid-state electrolytes. ...
