Abstract

The application of lithium (Li) metal anodes in Li metal batteries has been hindered by growth of Li dendrites, which lead to short cycling life. Here a Li-ion-affinity leaky film as a protection layer is reported to promote a dendrite-free Li metal anode. The leaky film induces electrokinetic phenomena to enhance Li-ion transport, leading to a reduced Li-ion concentration polarization and homogeneous Li-ion distribution. As a result, the dendrite-free Li metal anode during Li plating/stripping is demonstrated even at an extremely high deposition capacity (6 mAh cm⁻²) and current density (40 mA cm⁻²) with improved Coulombic efficiencies. A full cell battery with the leaky-film protected Li metal as the anode and high-areal-capacity LiNi_0.8Co_0.1Mn_0.1O₂ (NCM-811) (≈4.2 mAh cm⁻²) or LiFePO₄ (≈3.8 mAh cm⁻²) as the cathode shows improved cycling stability and capacity retention, even at lean electrolyte conditions.
