Research on the Anode Protection of Lithium

The anode of Lithium serves as the most ideal substitute for graphite anode. However, uncontrolled growth of lithium dendrite brings about service life and safety problems, which limit its commercial application. According to the thermodynamic and kinetic factors of lithium dendrite growth, many strategies have been proposed to inhibit the growth of lithium dendrite, such as structural composite lithium metal anode, optimizing SEI film, using solid electrolyte, etc. This paper reviewed the development process of different strategies, and analyzed their advantages and limitations, looking forward to the possible direction of inhibiting the growth of lithium dendrite.
