“…Morozova et al, recently called into question the stability of some commonly used TFSI derived ILs, when used with Al/Al 2 O 3 electrodes [252]. They found that imidazolium based cations, as well as Pyr 1,2 , Pyr 1,3 , and Pyr 1,4 cations, each with TFSI anion, showed pronounced Al corrosion when KTFSI salt was used.…”

The heavy reliance of lithium-ion batteries has caused rising concerns on the sustainability of lithium and transition metal and the ethic issue around mining practice. Developing alternative energy storage technologies beyond lithium has become a prominent slice of global energy research portfolio. The alternative technologies play a vital role in shaping the future landscape of energy storage, from electrified mobility to the efficient utilisation of renewable energies and further to large-scale stationary energy storage. Potassium-ion batteries (PIBs) are a promising alternative given its chemical and economic benefits, making a strong competitor to lithium-ion and sodium-ion batteries for different applications. However, many are unknown regarding potassium storage processes in materials and how it differs from lithium and sodium and understanding of solid-liquid interfacial chemistry is massively insufficient in PIBs. Therefore, there remain outstanding issues to advance the commercial prospects of the PIB technology. This Roadmap highlights the up-to-date scientific and technological advances and the insights into solving challenging issues to accelerate the development of PIBs. We hope this Roadmap aids the wider PIB research community and provides a cross-referencing to other beyond lithium energy storage technologies in the fast-pacing research landscape.

Over the past decade, concerns over the sustainability of lithium‐ion batteries (LIBs) have arisen due to the scarcity of critical elements such as lithium (Li), nickel (Ni), and cobalt (Co), prompting the exploration of alternative and complementary electrochemical energy storage technologies. Due to the more abundant resources compared to contemporary LIBs and the potentially higher specific energy than the emerging sodium‐ion batteries (SIBs), potassium‐ion batteries (PIBs) have attracted intensive research interest as a promising alternative to existing technologies. Nevertheless, the development of practical PIBs remains in its infancy. In this perspective, the various electrode materials and electrolytes reported for PIBs from an application point of view and identifying the most promising ones with high practical interest are first concisely discussed. Then, the pack‐level specific energy, energy density, and cost analyses are presented for several PIBs chemistries, which are also compared with representative LIBs and SIBs to demonstrate the advantages of PIBs. After that, a succinct discussion is presented to evaluate the practicality of potassium metal batteries. Finally, the challenges associated with the commercialization of PIBs, providing future critical research fronts for the development of practical high‐performance PIBs are outlined.
