3D nanocubes NiCo-PBA sulfide for high-performance supercapacitors

Stable Hierarchical Porous Heterostructure Ni2P/NC@CoNi2S4 Fabricated via the NiCo-LDH Template Strategy for High-Performance Supercapacitors

“…The ASC delivers a notable energy density of 73.68 Wh kg –1 at a power density of 700 W kg –1 , maintaining an energy density of 49.29 Wh kg –1 at a higher power density of 7000 W kg –1 . These performances surpass many similar ASC devices based TMPs or TMSs, such as NiCoS-PBA//AC (800.1 W kg –1 , 61.7 Wh kg –1 ), Ni 2 CoS 4 @(NiCo)­Se 2 //AC (480 W kg –1 , 53 Wh kg –1 ), P–Ni 2 S 3 /Co 3 S 4 /ZnS//AC (800 W kg –1 , 48 Wh kg –1 ), NiCoP//AC HSC (373.3 W kg –1 , 41.3 Wh kg –1 ), NiCoP/Co­(OH) 2 //AC ASC (750 W kg –1 , 37 Wh kg –1 ), rGO/MXene@Fe 2 O 3 //rGO/MXene@NiCoP (700.34 W kg –1 , 29.4 Wh kg –1 ), Ni–Co–P/PO x /NC/NF//RGO/NF (800 W kg –1 , 37.59 Wh kg –1 ), and others (Figure h and Table S3). Furthermore, two ASC devices in series are successfully employed to light a green LED lamp (Figure h) and drive an electric fan (Figure S21), demonstrating their potential practical applications.…”

Enhanced redox kinetics of Prussian blue analogues for superior electrochemical deionization performance

“…This discrepancy highlights the altered ionic diffusion kinetics attributed to the Mn substitution. 18,37,38 Apart from the ionic kinetics, the electronic properties of NiHCF and Mn–NiHCF have also been compared through the total density of state (TDOS) and partial density of state (PDOS). From the TDOSs of NiHCF and Mn–NiHCF (Fig.…”

From lab to field: Prussian blue frameworks as sustainable cathode materials

“…PB can be generated via an electrochemical reaction involving an acidic solution containing Fe 3+ and [Fe(CN) 6 ] 4− ions. 79 Using chronoamperometry, Fe 4 [Fe(CN) 6 ] 3 · x H 2 O nanowires were fabricated on a polycarbonate membrane at 0.3 V potential versus a saturated calomel electrode by immersing the working electrode in a solution of H 3 BO 4 , K 3 Fe(CN) 6 , FeCl 3 and KCl. 80 The synthesis of Fe 4 [Fe(CN) 6 ] 3 · x H 2 O nanotubes was accomplished via electrodeposition on porous aluminum foil that had been anodized.…”
