“…To further analyze the dual ion migration induced by the zwitterionic functional groups, we calculated the diffusion coefficient of the zinc ions ( D Zn ) in the ZSC‐gel. [ 55 ] As shown in Figure S19, Supporting Information, D Zn of the PAM‐gel was calculated to be only 0.46 × 10 −17 m 2 s −1 , whereas the ZSC‐gel exhibited a considerably higher ion transport capacity (1.18 × 10 −17 m 2 s −1 ). This demonstrates the superior ion transfer kinetics of the ZSC‐gel achieved with the polyzwitterions.…”

“…Remarkably, in the following cycles, the specific capacity is slightly increased (corresponding to the activation process) and stabilized at 378 mAh g −1 with CE of about 100% after 50 cycles (Fig. 5c), which is much higher than state-of-the-art quasi-solid-state ZIBs (e.g., ~ 200 mAh g −1 for zinc orthovanadate array//Zn array [68], and ~ 300 mAh g −1 for V 5…”

HIGHLIGHTS• 3D flower-like architecture assembled by NH 4 V 4 O 10 nanobelts (3D-NVO) was fabricated.• The Zn 2+ ion was intercalated into NVO cathode within the interlayer region (NH 4 V 4 O 10 ↔ Zn x NH 4 V 4 O 10 ).• The 3D-NVO cathode could deliver a large reversible capacity of 485 mAh g −1 at a current density of 100 mA g −1 for zinc-ion battery.ABSTRACT Given the advantages of being abundant in resources, environmental benign and highly safe, rechargeable zinc-ion batteries (ZIBs) enter the global spotlight for their potential utilization in large-scale energy storage. Despite their preliminary success, zinc-ion storage that is able to deliver capacity > 400 mAh g −1 remains a great challenge. Here, we demonstrate the viability of NH 4 V 4 O 10 (NVO) as high-capacity cathode that breaks through the bottleneck of ZIBs in limited capacity. The firstprinciples calculations reveal that layered NVO is a good host to provide fast Zn 2+ ions diffusion channel along its [010] direction in the interlayer space. On the other hand, to further enhance Zn 2+ ion intercalation kinetics and long-term cycling stability, a three-dimensional (3D) flower-like architecture that is self-assembled by NVO nanobelts (3D-NVO) is rationally designed and fabricated through a microwave-assisted hydrothermal c b NH 4 Zn 2+ Zn 2+ + 700 550 400 250 100 Discharge Charge Coulombic efficiency 0 1 0 2 0 Cycle number 30 40 50 Coulombic efficiency (%) 100 80 60 40 20 0 485 mAh g −1 Capacity (mAh g −1 )method. As a result, such 3D-NVO cathode possesses high capacity (485 mAh g −1 ) and superior long-term cycling performance (3000 times) at 10 A g −1 (~ 50 s to full discharge/charge). Additionally, based on the excellent 3D-NVO cathode, a quasi-solid-state ZIB with capacity of 378 mAh g −1 is developed.

Aqueous zinc ion batteries: focus on zinc metal anodes

Despite the prevalence of lithium ion batteries in modern technology, the search for alternative electrochemical systems to complement the global battery portfolio is an ongoing effort. The search has resulted in numerous candidates, among which mildly acidic aqueous zinc ion batteries have recently garnered significant academic interest, mostly due to their inherent safety. As the anode is often fixed as zinc metal in these systems, most studies address the absence of a suitable cathode for reaction with zinc ions. This has led to aggressive research into viable intercalation cathodes, some of which have shown impressive results. However, many investigations often overlook the implications of the zinc metal anode, when in fact the anode is key to determining the energy density of the entire cell. In this regard, we aim to shed light on the importance of the zinc metal anode. This perspective offers a brief discussion of zinc electrochemistry in mildly acidic aqueous environments, along with an overview of recent efforts to improve the performance of zinc metal to extract key lessons for future research initiatives. Furthermore, we discuss the energy density ramifications of the zinc anode with respect to its weight and reversibility through simple calculations for numerous influential reports in the field. Finally, we offer some perspectives on the importance of optimizing zinc anodes as well as a future direction for developing high-performance aqueous zinc ion batteries.
