“…However, it is important to mention that the used Dunn's equation is postulated considering an ideal scenario, where the capacitive current varies linearly with the scan rate or the diffusion current has a linear relationship with the square root of the scan rate, with no shifting of the peak potential with scan rates. 64 However, this is not the ideal case, as most of the battery materials show a slight shift in peak potential with scan rates, and the Dunn's equation gives only an approximation of the relative contribution of the diffusion-controlled and capacitance-controlled current. 65−68 Further, the rate capacity study carried out at different current densities of 0.1, 0.2, 0.4, 0.6, 0.8, 1, and 2 A/g (Figure 5b) showed specific capacities of 556, 360, 276, 214, 193, 171, and 115 mAh/g, respectively (from the second cycle).…”

Herein we demonstrate the fabrication of a highperformance rechargeable zinc ion battery based on a laser-scribed carbon (LSC)-supported electrodeposited zinc anode and vanadium oxide (V 5 O 12 •6H 2 O) cathode with a planar-interdigitated electrode architecture and a polymeric solid electrolyte. This is the first report on a full-cell Zn//V 5 O 12 •6H 2 O planar flexible battery where a practical zinc loading (∼76 times that of the cathode loading) is maintained. The electrodeposited Zn@LSC anode showed excellent stability with very low polarization over the tested 500 h (750 cycles). We demonstrate a high initial capacity of 325 mAh/g for the Zn//V 5 O 12 •6H 2 O planar battery at 2 A/g in a 3 M ZnSO 4 aqueous electrolyte. However, the capacity dropped to 70 mAh/g only after 1000 cycles. Nonetheless, the cell performance, in particular the cycle stability, was significantly improved when the aqueous electrolyte was replaced with a gelatin/ZnSO 4 / glutaraldehyde-based solid-state electrolyte. The solid-state planar battery showed a high initial capacity of 556 mAh/g at 0.1 A/g current corresponding to an energy density of 381 Wh/kg active cathode and an impressive cycle stability with only 0.0067% capacity loss per cycle over 5500 cycles at 2 A/g. The cell also demonstrated excellent flexibility with comparable specific capacity under different bending conditions. The solid-state device exhibited a high areal energy density of 72 and 14 μWh/cm 2 at the corresponding areal power density of 130 and 2511 μW/cm 2 , respectively. Overall, the rapid (complete device fabrication in ∼2 h) and scalable fabrication approach, high performance with excellent safety features, and accompanying high flexibility make the as-fabricated Zn// V 5 O 12 •6H 2 O planar flexible battery suitable for next-generation flexible electronics applications.

Faradaic capacitive deionization (FCDI) with attractive ion‐capture capacity, outstanding durability, and potential compatibility in high‐salinity water has been recognized as the robust alternative to address the alarming freshwater scarcity. The further innovation of boosting electrode materials is the indispensable requisite for highly efficient FCDI application. Herein, a low‐crystalline nitrogen‐doped carbon quantum dots modified Mg2+‐pillar preintercalated V3O7 (i.e., NCQDs/Mg‐V3O7) heterostructure is assembled via an ingenious one‐spot hydrothermal avenue, and is investigated as the advanced FCDI electrode for desalination application. Taking advantages of the synergic effect of unique microstructure, improved electronic conductivity, and exceptional structural durability, the NCQDs/Mg‐V3O7 electrode delivers an admirable gravimetric adsorption capacity of 54.32 mg g−1 in a NaCl solution of 1500 mg L−1 and attractive cyclic durability. Further, density functional theory calculations verify the intense interface electron coupling interaction between tri‐components, enabling the significantly promoting Na+ capture capability. The synergy removal mechanism is clarified by ex‐situ X‐ray photoelectron spectroscopy and in‐situ Raman tests. Additionally, the average removal efficiency of hybrid electrode attains 93.75% in the simulated wastewater comprising the NaCl of 50 mg L−1 and diverse metal nitrates from 10 to 100 mg L−1 for each, certifying the great prospects for practical wastewater treatment.
