Reversible surface reconstruction of Na3NiCO3PO4: A battery type electrode for pseudocapacitor applications

Effect of Electrolytic Cations on a 3D Cd-MOF for Supercapacitive Electrodes

“…Therefore, based on the electrode performance in 1 M NaOH, the detailed studies are discussed here. From the CV plot in 1 M NaOH, a couple of redox peaks (oxidation and reduction) are found, verifying that the prepared materials comprise strong battery-type pseudocapacitive behavior (Figure c) . Moreover, the area under the curve increases at higher scan rates due to better electrochemical performance .…”

Two-step synthesis of a-NiCu(OH)2CO3/Na3NiCuCO3PO4: a battery-type electrode for pseudocapacitor applications

“…24 Our recent work shows that the alkaline etching of hydrothermally prepared Na 3 NiCO 3 PO 4 in 1 M KOH is a promising strategy for facilitating structural reconstruction, and thereby achieving a high specific surface area and battery-type pseudocapacitor behavior. 27 In this work, we report the two-step synthesis of a-NiCu(OH) 2 -CO 3 /Na 3 NiCuCO 3 PO 4 composite materials using the alkaline etching of hydrothermally prepared Na 3 NiCuCO 3 PO 4 in 1 M KOH solution at room temperature. Using these surfacemodified composite materials as device electrodes can provide many important advantages as follows: (i) the entire synthesis process is environmentally friendly and cost-effective without the use of any toxic solvents and surfactants; (ii) the alkaline etching of the electrode surface creates the mesoporous structure, and the high specific surface area (171.14 m 2 g À1 ) assists the electrolytes to pass through the porous architecture more efficiently and facilitate high faradaic reactions.…”
