Special Issue Introduction

Potassium is a highly abundant alkali metal and can realistically replace lithium in rocking chair batteries, at least for stationary applications when batteries are coupled with solar panels or wind plants. Indeed, in these cases, battery size is not relevant, while the investment cost becomes a primary target. In addition, potassium can be used in combination with light and cheap aluminum as current collector (instead of copper), since it does not alloy with this metal during the charge-discharge process. Potassium offers peculiar advantages with respect to other post-lithium cations (e.g., sodium); for example, it shows a more negative redox potential (−2.936  V vs. SHE), which is fairly close to that of lithium (−3.040  V vs. SHE). Also, K+ is a weaker Lewis acid with respect to sodium and lithium cations, thus exhibiting lower solvation (i. e., smaller solvated ions) in the liquid electrolyte. For all these reasons, the research on potassium-ion batteries has been strongly sustained over the last 3-5 years and the scientific community has developed several electrode and electrolyte materials that can reversibly store and release potassium ions.

This special issue intends to collect cutting-edge trends in the potassium batteries field, from materials design to cell fabrication and testing, as well as computational studies and market-level analysis.
