摘要
Aqueous metal batteries have attracted particular attention due to their low cost,environmental friendliness,and high safety.However,they still face challenges that hinder practical applications,including the oxygen and hydrogen evolution and formation of the dendrite.Herein,we propose a novel hybrid-ion battery with Ni metal as the anode.Due to the electrostatic shielding effect of Li^(+),the surface of deposited Ni is smooth and dendrite-free,which enables an ultralong lifespan of over 4000 h and high coulombic efficiency over 99.5%.
