“…Unlike the previously reported bulk layered materials 37,[39][40][41][42] , the 2D VOPO 4 -graphene multilayered heterostructure showed increased interlayer spacing upon K + ion intercalation. It should be noted that the reported structures were bulk layered compounds with water or metal ions in the interlayer space.…”

Beyond-lithium-ion batteries are promising candidates for high-energy-density, low-cost and large-scale energy storage applications. However, the main challenge lies in the development of suitable electrode materials. Here, we demonstrate a new type of zero-strain cathode for reversible intercalation of beyond-Li + ions (Na + , K + , Zn 2+ , Al 3+) through interface strain engineering of a 2D multilayered VOPO 4-graphene heterostructure. In-situ characterization and theoretical calculations reveal a reversible intercalation mechanism of cations in the 2D multilayered heterostructure with a negligible volume change. When applied as cathodes in K +-ion batteries, we achieve a high specific capacity of 160 mA h g −1 and a large energy density of~570 W h kg −1 , presenting the best reported performance to date. Moreover, the as-prepared 2D multilayered heterostructure can also be extended as cathodes for highperformance Na + , Zn 2+ , and Al 3+-ion batteries. This work heralds a promising strategy to utilize strain engineering of 2D materials for advanced energy storage applications.

“…As a consequence, the development of alternative aqueous rechargeable batteries based on some other earth-abundant elements turns out to be urgent and more meaningful. Therefore, the monovalent (Na + , K + ) and/or multivalent (Zn 2+ , Mg 2+ , and Al 3+ ) cation based aqueous secondary batteries have been intensively explored recently (Wessells et al, 2011;Zhao et al, 2016;Suo et al, 2017;Wang et al, 2020).…”

Recent Progress in “Water-in-Salt” Electrolytes Toward Non-lithium Based Rechargeable Batteries

et al. 2020

View full text Add to dashboard Cite

Aqueous non-lithium based rechargeable batteries are emerging as promising energy storage devices thanks to their attractive rate capacities, long-cycle life, high safety, low cost, environmental-friendliness, and easy assembly conditions. However, the aqueous electrolytes with high ionic conductivity are always restricted by their intrinsically narrow electrochemical window. Encouragingly, the highly concentrated "water-in-salt" (WIS) electrolytes can efficiently expand the stable operation window, which brings up a series of aqueous high-voltage rechargeable batteries. In the mini review, we summarize the latest progress and contributions of various aqueous electrolytes for non-lithium (Na + , K + , Zn 2+ , Mg 2+ , and Al 3+) based rechargeable batteries, and give a brief exploration of the operating mechanisms of WIS electrolytes in expanding electrochemically stable windows. Challenges and prospects are also proposed for WIS electrolytes toward aqueous non-lithium rechargeable metal ion batteries.

“…Besides Li‐ion batteries, various multivalent ion batteries have drawn great interest in energy storage and conversion applications, such as Al‐, Ca‐ and Mg‐ion solid state or flexible batteries 15,21‐23 . As another multivalent ion battery, the explorations of zinc‐ion batteries (ZIBs) (especially Mn‐based ZIBs) have been initiated for decades (Figure 1A).…”

Flexible Zn‐ion batteries based on manganese oxides: Progress and prospect

et al. 2020

View full text Add to dashboard Cite

The ever‐growing market of wearable electronic devices has greatly stimulated the rapid development of flexible Zn‐ion batteries (ZIBs). Manganese oxides are one of the most commonly used hosts for zinc ion accommodation and thus receive particular research interest for high‐performance flexible ZIB constructions. In this review, a comprehensive summary of the recent development of flexible ZIBs with manganese oxides as cathode materials is presented. Apart from the brief introduction of flexible electronic devices and ZIBs, the charge storage mechanisms and crystal structures of various manganese oxides are summarized. Modifications of the cathode materials in terms of morphology, conductivity, structures, and flexibilities are illustrated in detail, together with the demonstration of structure‐performance relationships and applications in flexible ZIBs. Finally, limitations to be overcome are indicated and the future work directions are proposed.
