The sodium (potassium)-metal anodes combine low-cost, high theoretical capacity, and high energy density, demonstrating promising application in sodium (potassium)-metal batteries. However, the dendrites' growth on the surface of Na (K) has impeded their practical application. Herein, density functional theory (DFT) results predict Na Te/K Te is beneficial for Na /K transport and can effectively suppress the formation of the dendrites because of low Na /K migration energy barrier and ultrahigh Na /K diffusion coefficient of 3.
