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.

“…ILs are liquids at room temperature composed of a pair of cation and anion-like salts. They usually feature low vapor pressure, high ionic conductivity, non-flammability, and wide EWs [ 57 , 58 ]. In particular, the exclusion of solvents ingeniously avoids obvious concentration gradients when both cations and anions are concurrently involved in electrode reactions.…”

High-voltage potassium-based batteries are promising alternatives for lithium-ion batteries as next-generation energy storage devices. The stability and reversibility of such systems depend largely on the properties of the corresponding electrolytes. This review first presents major challenges for high-voltage electrolytes, such as electrolyte decomposition, parasitic side reactions, and current collector corrosion. Then, the state-of-the-art modification strategies for traditional ester and ether-based organic electrolytes are scrutinized and discussed, including high concentration, localized high concentration/weakly solvating strategy, multi-ion strategy, and addition of high-voltage additives. Besides, research advances of other promising electrolyte systems, such as potassium-based ionic liquids and solid-state-electrolytes are also summarized. Finally, prospective future research directions are proposed to further enhance the oxidative stability and non-corrosiveness of electrolytes for high-voltage potassium batteries.

“…In our previous reports, graphitic onion-like carbon (GOC) with a concentric arrangement of carbon layers has good electrical conductivity and structural stability, which provides a new opportunity to improve the performance of alkali metal battery storage materials. , However, the diffusion limitation of ions within graphite has been demonstrated to be the primary obstacle limiting kinetics . Despite the superior cyclic stability of GOC, the inadequate K + intercalation layer spacing and low active sites of GOC hinder its application as a high-power anode material in PIBs.…”

Potassium-ion batteries (PIBs) are attractive energy storage devices due to the abundant low-cost potassium resources, and graphite is one of the most competing anodes of PIBs. Nevertheless, graphite often suffers from sluggish kinetics, large volume variations, and high activity of K + , leading to poor rate and low-temperature performance, insufficient cyclability, and safety issues. Herein, mild-expanded graphitic onion-like carbon (MEGOC) with an enlarged interlayer distance is prepared from confined graphitic onion-like carbon by liquid-phase oxidation and slow thermal reduction, which can accommodate volume variations and promote potassium diffusion. Meanwhile, using triethyl phosphate, a nonflammable and low-melting-point electrolyte ensures safety and low-temperature operation performance. In the nonflammable potassium-ion electrolyte, MEGOC exhibits long cycle life at a high rate (175 mA h g −1 at 2C after 1500 cycles) and superior low-temperature performance (165 mA h g −1 at −40 °C). Furthermore, an assembled nonflammable potassium-ion capacitor with MEGOC as the anode exhibits high reversibility and superior energy/power density at ambient and low temperatures. Accordingly, combining structural engineering and electrolyte engineering is an effective strategy for improving the safety and high performance of potassium-based electrochemical energy storage devices.
