“…An operando XRD study identified reversible structural changes that engender this material with an excellent electrochemical performance that is attributed to its open and flexible framework. Jiang et al showed that FEC additives are preferred when PW K 1.6 Mn[Fe(CN) 6 ] 0.96 ·0.27H 2 O in an EC:DEC electrolyte was used because K + ‐conducting passive layers are formed on the K metal. However, caution is required because FEC reduction results in the release of HF, which may degrade the PW materials following exposure to an acidic electrolyte (Figure g).…”

The topic of sustainable and eco-friendly energy storage technologies is an issue of global significance. To date, this heavy burden is solely addressed by lithium-ion battery technology. However, the ongoing depletion of limited global lithium resources has restricted their future availability for Li-ion battery technology, and hence, a significant price increase is expected. This grim situation is the driving force for the development of the "beyond Li-ion battery" strategy involving alternatives that have several advantages over conventional Li-ion batteries in terms of cost, durability, safety, and sustainability. Potassium, the closest neighboring alkali element after sodium, offers some unique advantages over lithium and sodium as a charge carrier in rechargeable batteries. Potassium intercalation chemistry in potassium-ion batteries (KIBs) is successfully demonstrated to be compatible with Li-ion batteries and sodium-ion batteries. In addition to KIBs, potassium-sulfur and potassium-oxygen batteries have emerged as new energy-storage systems due to their low costs and high specific energy densities. This review covers the key technological developments and scientific challenges for a broad range of rechargeable potassium batteries, while also providing valuable insight into the scientific and practical issues concerning the development of potassium-based rechargeable batteries.in the price of lithium is primarily ascribed to the increased demand for LIB production for use in electric vehicles and energy-storage systems. For this reason, the development of sodium-ion batteries has steadily increased because SIBs and LIBs use a similar intercalation chemistry. One notable feature of an SIB is that the use of graphite, which is common in LIBs, is unfavorable owing to the difficulties associated with the insertion of Na + into the graphite interlayers. Strikingly, K + ions do intercalate into graphene layers; accordingly, graphite is available to be used as a KIB-anode material. One of the merits of a graphite anode is its favorable energy density. It is therefore possible for KIBs to compete commercially with SIBs that use hard carbon as an anode material. However, additional research is required to scale the development of KIBs to that of SIBs, at the very least. To highlight recent KIB progress, several candidate electrode materials, electrolytes, binders, and full cells are described in this review. capacity was reduced (Figure 4c,d). Notably, many voltage plateaus are associated with several phase transitions due to K + / vacancy ordering in the oxide lattice, which progresses via a P3-biphasic-O3-biphasic-X phase by analogy with the O3 phase ( Figure 4e). This phase transition is reversible during discharge to 1.5 V. Density functional theory (DFT) calculations provided

Potassium‐ion batteries (PIBs) as a promising supplement to lithium‐ion batteries have drawn great attention attributing to the abundant potassium resources, the fast‐ionic conductivity of potassium ions in electrolyte, and the low standard redox potential of potassium. However, the development of PIBs is still in its infancy, which is largely restricted by the fact that the electrode materials, especially the cathode materials of PIBs, are far from satisfactory in practical applications regarding the capacity, voltage, and cycle life. Therefore, most of current research efforts have been devoted to exploring new and high‐performance electrode materials for achieving PIBs with high capacity and voltage as well as excellent cyclability. In this review, the recent advancements on cathode materials for PIBs are specially summarized. Besides, technological developments, scientific challenges, and future research opportunities of cathode materials for PIBs are also briefly outlooked.

Potassium‐ion batteries (PIBs) are promising candidates to substitute lithium‐ion batteries (LIBs) as large‐scale energy storage devices. However, developing suitable anode materials is still a great challenge that has limited the anticipated application of PIBs. Herein, the interlayer expanded SnS2 nanocrystals anchored on nitrogen‐doped graphene nanosheets (SnS2@NC) are synthesized following a facile one‐step hydrothermal strategy. Relying on the exquisite nanostructure with larger interlayer spacing, the K+ ions diffusion and charge transfer will be accelerated. In addition, the intense coupling interaction between nitrogen‐doped graphene nanosheets and SnS2 can endow a sturdy nanostructure, avoiding the collapse and aggregation of SnS2 nanocrystals upon cycling. Based on the above merits, the as‐prepared SnS2@NC anode exhibits improved electrochemical performanc (desirable rate capability of 206.7 mAh g−1 at 1000 mA g−1 and advanced cyclic property of 262.5 mAh g−1, while after 100 cycles at 500 mA g−1). More importantly, multistep reactions of K+ storage mechanism combining with intercalation, conversion and alloying reactions are clearly illustrated by combined in‐situ XRD measurement and ex‐situ TEM detection. This strategy of enhancing K+ storage performances has a great potential for other electrode materials.
