“…The specific capacity of the 10th cycle was ≈65.4 mAh·g −1 , which is close to the theoretical capacity (67.0 mAh·g −1 ) with the formation of K 0.4 MoS 2 . Other investigated intercalation type anodes for KIBs are Ti 3 C 2 MXene and siloxene . However, the low theoretical and experimental capacities of this material are the obstacles to the further investigation/growth of this material as an anode for KIBs.…”

Demand for energy in day to day life is increasing exponentially. However, existing energy storage technologies like lithium ion batteries cannot stand alone to fulfill future needs. In this regard, potassium ion batteries (KIBs) that utilize K ions in their charge storage mechanism have attracted considerable attention due to their unique properties and are therefore established as one of the future battery systems of interest among the scientific community. Nevertheless, the development and identification of appropriate electrode materials is very essential for practical applications. This review features the current development in KIBs electrode and electrolyte materials, the present challenges facing this technology (in the commercial aspect), and future aspects to develop fully functional KIBs. The potassium storage mechanisms, evolution of the KIBs, and the advantages and disadvantages of each category of materials are included. Additionally, various approaches to enhance the electrochemical performances of KIBs are also discussed. This review is not only an amalgamation of different viewpoints in literature, but also contains concise perspectives and strategies. Moreover, the potential emergence of a novel class of K‐based dual ion batteries is also analyzed for the first time.

“…2D Ti 3 C 2 T x materials, possessing metallic conductivity and a hydrophilic surface in addition to their layered structure resembling that of expanded graphite, are a promising type of electrode material for energy‐storage devices such as SCs, LIBs, LSBs, and beyond LIBs . Over the past years, starting with Gogotsi's reports, theoretical and experimental studies have witnessed the potential application of Ti 3 C 2 T x in electrochemical energy storage.…”

“…For a 2D structural material, a larger interlayer distance means smaller volume changes and a lower intercalation barrier . Inspired by the facts that the interlayer spacing of Ti 3 C 2 T x can be artificially tuned and that its surface can be modified, researchers have made numerous efforts in using Ti 3 C 2 T x and Ti 3 C 2 T x ‐based composites for LIBs, SIBs, LSBs, and other kinds of batteries . Chemical modification, structural design, and combination with other materials are the three most popular strategies to improve the performance of rechargeable batteries.…”

“…In addition to the significant advances of MXenes for alkali ion storage, the rational synthesis of novel MXene‐based nanoarchitectures is indispensable for enhancing their performance. For example, alkalized Ti 3 C 2 T x nanoribbons (a‐Ti 3 C 2 MNRs) were produced by the shaking of pristine Ti 3 C 2 T x in aqueous KOH solution, resulting in a 3D porous framework ( Figure a) . Benefiting from the expanded interlayer spacing of a‐Ti 3 C 2 , the narrow width of nanoribbons and the 3D interconnected porous frameworks enhanced ion reaction kinetics and improved structure stability; as a result, the resulting a‐Ti 3 C 2 anodes showed excellent potassium storage performance with a high reversible capacity of 42 mA h g −1 at 200 mA g −1 after 500 cycles (Figure c).…”

Ti C T , a typical representative among the emerging family of 2D layered transition metal carbides and/or nitrides referred to as MXenes, has exhibited multiple advantages including metallic conductivity, a plastic layer structure, small band gaps, and the hydrophilic nature of its functionalized surface. As a result, this 2D material is intensively investigated for application in the energy storage field. The composition, morphology and texture, surface chemistry, and structural configuration of Ti C T directly influence its electrochemical performance, e.g., the use of a well-designed 2D Ti C T as a rechargeable battery anode has significantly enhanced battery performance by providing more chemically active interfaces, shortened ion-diffusion lengths, and improved in-plane carrier/charge-transport kinetics. Some recent progresses of Ti C T MXene are achieved in energy storage. This Review summarizes recent advances in the synthesis and electrochemical energy storage applications of Ti C T MXene including supercapacitors, lithium-ion batteries, sodium-ion batteries, and lithium-sulfur batteries. The current opportunities and future challenges of Ti C T MXene are addressed for energy-storage devices. This Review seeks to provide a rational and in-depth understanding of the relation between the electrochemical performance and the nanostructural/chemical composition of Ti C T , which will promote the further development of 2D MXenes in energy-storage applications.

“…However, the relatively limited reserve and uneven geographical distribution of the lithium resources give a tremendous challenge to LIBs for meeting the continuously increasing requirement on the high performance‐to‐cost ratios. Therefore, other metal ion batteries such as sodium (Na) ion batteries (SIBs), potassium (K) ion batteries (PIBs), and aluminum ion batteries have gained notable attention. Moreover, SIBs and PIBs are of particular interest because of the similar physicochemical properties to Li, and relatively high abundance, low cost, and geographically uniform distribution of Na and K. Meanwhile, it is noteworthy that the standard electrode potential of K/K + (−2.93 V vs SHE) is lower than that of Na/Na + (−2.71 V vs SHE), indicating a higher working voltage for PIBs.…”

Dual carbon-based potassium dual ion batteries (K-DCBs) have recently attracted ever-increasing attention owing to the potential advantages of high performance-to-cost ratio, good safety, and environmental friendliness. However, the reported K-DCBs still cannot simultaneously meet the requirements of high capacity, long cycling stability, and low cost, which are necessary for practical applications. In this study, a K-DCB with good comprehensive performance including capacity, cycling stability, medium discharge voltage, and energy density is developed by introducing the optimal cathode and anode materials, i.e., KS6 and natural graphite, respectively. An initial capacity of ≈54.6 mAh g and 92.5% capacity retention after 400 cycles can be delivered in a wide voltage window of 2.4-5.4 V at the current density of 100 mA g . A high medium discharge voltage around 4.2 V and an energy density up to 158.3 Wh kg are meanwhile delivered by the K-DCB. In addition, the working mechanism of the devices is understood in detail. It is believed that valuable contributions to the electrochemical performance improvement of the related devices toward practical applications can be provided by this study.
