Liquid K-Na Alloy Anode Enables Dendrite-Free Potassium Batteries
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)6 cathode, the working cation becomes K+ to give a potassium battery of long cycle life with an...

Summary: | 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)6 cathode, the working cation becomes K+ to give a potassium battery of long cycle life with an acceptable capacity at high charge/discharge rates. |
