Special Issue Information

Dear Colleagues,

In the past decade, lithium-ion batteries have greatly contributed to improving our daily life. However, concerns surrounding the depletion of lithium resources have promoted the development of new types of electrical energy systems. As an alternative to lithium-ion batteries, rechargeable potassium batteries have attracted significant attention due to their high energy density and sustainability. Hence, the importance of rechargeable potassium batteries as an alternative of commercial Li-ion batteries has been highlighted by various scientific societies. In this Special Issue, we wish to present informative works and recent achievements on innovative functional materials for rechargeable potassium batteries, with the aim to facilitate and promote research in this filed.

It is our great pleasure to invite you to submit original research papers, short communications, or state-of-the-art feature articles (comments or reviews) within the scope of this Special Issue. This Special Issue will discuss key technological developments and scientific information on a broad range of rechargeable potassium batteries, such as K-ion, K-O2, K-S, K-metal, and all-solid-state potassium batteries.

Abstract
The use of chalcogenide elements, such as sulfur (S) and selenium (Se), as cathode materials in rechargeable lithium (Li) and sodium (Na) batteries has been extensively investigated.

The use of chalcogenide elements, such as sulfur (S) and selenium (Se), as cathode materials in rechargeable lithium (Li) and sodium (Na) batteries has been extensively investigated. Similar to Li and Na systems, rechargeable potassium–sulfur (K–S) and potassium–selenium (K–Se) batteries have recently attracted substantial interest because of the abundance of K and low associated costs. However, K–S and K–Se battery technologies are in their infancy because K possesses overactive chemical properties compared to Li and Na and the electrochemical mechanisms of such batteries are not fully understood. This paper summarizes current research trends and challenges with regard to K–S and K–Se batteries and reviews the associated fundamental science, key technological developments, and scientific challenges to evaluate the potential use of these batteries and finally determine effective pathways for their practical development.
