Electrochemical potassium storage explores the principles, materials, and technological developments of a variety of battery technologies based on electrochemical potassium storage. It covers the principles of potassium-ion batteries (organic and aqueous electrolytes), potassium metal batteries, potassium-sulfur (selenium) batteries, and potassium-oxygen batteries, as well as the development of the electrode materials of these batteries and the understanding of electrochemical cell operations.
Batteries using potassium ions as the charge carrier to store energy operate via different electrochemical processes and have different features of materials electrochemistry compared to lithium-based batteries. Thus, battery technologies based on electrochemical potassium storage exhibit different performance strengths, potentially having diverse market applications. This is particularly important for the search for environmentally and economically sustainable alternatives to conventional lithium-ion batteries in a wide range of applications.
