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 Na MnFe(CN) cathode, the working cation becomes K to give a potassium battery of long cycle life with an acceptable capacity at high charge/discharge rates.
摘要
一种 K-Na 液态合金可实现无枝晶高容量阳极；其与有机液态电解质不混溶，形成液-液阳极-电解质界面。与钠离子化的 NaMnFe(CN)阴极配合使用，工作阳离子变为 K，从而得到一种钾电池，其具有长循环寿命和可接受的高充放电速率容量。
