title: Liquid K-Na Alloy Anode Enables Dendrite-Free Potassium Batteries.
abstract: A K-Na liquid alloy allows a dendrite-free high-capacity anode; its immiscibility with an organic liquid electrolyte offers a liquid-liquid anode-electrolyte interface. Working with a sodiated Na2MnFe(CN)6cathode, the working cation becomes K+to give a potassium battery of long cycle life with an acceptable capacity at high charge/discharge rates.
