Abstract
The present work describes the successive ionic layer adsorption and reaction (SILAR) approach to binder-free synthesis of hydrous manganese phosphate [Mn3(PO4)2·7H2O] electrodes for Mg-ion supercapacitors. Structural and morphological analysis confirms the formation of microflowers composed of nanosheets of monoclinic Mn3(PO4)2·7H2O electrodes. The binder-free MP3 electrode with optimum thickness and a specific surface area of 16.3 m2 g-1 achieves the utmost specific capacitance (Csp) of 317 F g-1 at 1 A g−1 current density in MgSO4 electrolyte. The aqueous Mg-ion symmetric supercapacitor (Mg-ASS) device (SS/MP3//MgSO4//MP3/SS) demonstrates a Csp of 73 F g−1 and specific energy of 40.5 Wh kg−1 at 2 kW kg−1 specific power. The results showcase SILAR method is feasible to prepare binder-free Mn3(PO4)2·7H2O electrodes, contributing to the sustainable advancement of Mg-ion supercapacitors.
期刊介绍:
Solid State Communications is an international medium for the publication of short communications and original research articles on significant developments in condensed matter science, giving scientists immediate access to important, recently completed work. The journal publishes original experimental and theoretical research on the physical and chemical properties of solids and other condensed systems and also on their preparation. The submission of manuscripts reporting research on the basic physics of materials science and devices, as well as of state-of-the-art microstructures and nanostructures, is encouraged.
A coherent quantitative treatment emphasizing new physics is expected rather than a simple accumulation of experimental data. Consistent with these aims, the short communications should be kept concise and short, usually not longer than six printed pages. The number of figures and tables should also be kept to a minimum. Solid State Communications now also welcomes original research articles without length restrictions.
The Fast-Track section of Solid State Communications is the venue for very rapid publication of short communications on significant developments in condensed matter science. The goal is to offer the broad condensed matter community quick and immediate access to publish recently completed papers in research areas that are rapidly evolving and in which there are developments with great potential impact.
