“…[78] It is worth noting that the Zn 3 V 2 O 7 (OH) 2 •2H 2 O byproduct was not detected on the NCAVA electrode, suggesting the successful inhibition of vanadium dissolution (Figure S19, Supporting Information). [72,79] To understand the electrochemical reaction kinetics and charge storage mechanism of the NCAVA cathode, CV measurements at different scan rates were carried out to ascertain the diffusion-controlled and capacitive contributions. Two distinct pairs of redox peaks associated with the pseudocapacitive behaviors are clearly observed on all the CV curves obtained at the scan rates ranging from 0.1 to 0.6 mV s −1 (Figure S20, Supporting Information).…”

Inevitable dissolution in aqueous electrolytes, intrinsically low electrical conductivity, and sluggish reaction kinetics have significantly hampered the zinc storage performance of vanadium oxide‐based cathode materials. Herein, core–shell N‐doped carbon‐encapsulated amorphous vanadium oxide arrays, prepared via a one‐step nitridation process followed by in situ electrochemical induction, as a highly stable and efficient cathode material for aqueous zinc‐ion batteries (AZIBs) are reported. In this design, the amorphous vanadium oxide core provides unobstructed ions diffusion routes and abundant active sites, while the N‐doped carbon shell can ensure efficient electron transfer and greatly stabilize the vanadium oxide core. The assembled AZIBs exhibit remarkable discharge capacity (0.92 mAh cm−2 at 0.5 mA cm−2), superior rate capability (0.51 mAh cm−2 at 20 mA cm−2), and ultra‐long cycling stability (≈100% capacity retention after 500 cycles at 0.5 mA cm−2 and 97% capacity retention after 10 000 cycles at 20 mA cm−2). The working mechanism is further validated by in situ X‐ray diffraction combined with ex situ tests. Moreover, the fabricated cathode is highly flexible, and the assembled quasi‐solid‐state AZIBs present stable electrochemical performance under large deformations. This work offers insights into the development of high‐performance amorphous vanadium oxide‐based cathodes for AZIBs.

“…At present, soft-packed batteries with layered stack configurations are commonly adopted for FAMIBs. [109][110][111][112][113][114][115][116][117][118] The fabrication techniques for soft-packed batteries are mature, and the battery components would be compressed during the vacuum encapsulation procedure. However, the relatively rigid aluminum-plastic films used for packing severely inhibited the flexibility of the whole battery, making the minor bending to be the only bearable deformation for soft-packed FAMIBs.…”

Flexible aqueous batteries have been thriving with the growing demand for wearable and portable electrical devices. In particular, flexible aqueous multivalent ion batteries (FAMIBs), the charge carriers of which include Zn 2+ , Al 3+ , Mg 2+ , and Ca 2+ , have great potential for development owing to their high safety, high elemental abundance in the Earth's crust, and a multielectron redox mechanism with a high theoretical specific capacity. Therefore, for a comprehensive understanding of this developing field, it is necessary to summarize the recent research progress of FAMIBs in a timely manner.Herein, the advancements of the state-of-the-art FAMIBs are reviewed, and the prospects toward this field are also proposed. This study focuses on the rational material and configuration design for FAMIBs in recent studies to achieve high battery performances under deformation conditions, which is elaborated on by classification of the anode, cathode, hydrogel electrolyte, and configurations of FAMIBs. Besides, the electrochemical performance of FAMIBs under flexible conditions is also reviewed from the perspective of their working voltage, specific capacity, and cycling stability. Finally, the approaches to improve the performance of FAMIBs are comprehensively evaluated, followed by the outlook on the challenges and opportunities in future development of FAMIBs.

V-based materials have attracted wide attention as high capacity cathode materials for aqueous batteries owing to their unique structures, however, much efforts should be made to increase the rate performance and solve the issue of fast capacity fading to meet the ever-growing need for the low-cost and safe energy storage devices. Herein, a novel S/VOx composite is synthesized via a very simply in-situ electrochemical induced phase transition from VS4. As prepared composite electrode could deliver an initial discharge capacity of 376 mAh g-1 at a current density of 0.05 A g-1, much higher than that of VS4 (150 mAh g-1). Moreover, it shows a good discharge capacity of 260 mAh g-1 at 2 A g-1 with a retention of ~100% over 2000 cycles, indicating an impressive electrochemical stability. The outstanding Zn2+ storage performance could be attributed to the characteristics of unique composite structure, highly reversible electrochemical reactions, and fast Zn2+ transport.
