Abstract
Iron-based Prussian blue analogs (PBAs) are synthesized using a modified coprecipitation approach at different temperatures to study the effect of coprecipitation reaction temperature on structural and electrochemical performance. The experimental results showed that the iron-based PBAs transferred from the cubic structure to the monoclinic phase as the temperature increased from 5 °C to 60 °C, with the former exhibiting rich-in-boundary morphology and the latter showing a well-defined cubic shape. The electrochemical performance of the samples is closely related to the structure: the PBAs with monoclinic structures exhibit a higher charge/discharge specific capacity than those of PBAs with cubic structures. In addition, the samples are further treated at 270 °C, new phases are probed, and the charge/discharge specific capacity for the HT-PB-60 sample is significantly improved by more than 36.15%.
期刊介绍:
The Journal of Solid State Electrochemistry is devoted to all aspects of solid-state chemistry and solid-state physics in electrochemistry.
The Journal of Solid State Electrochemistry publishes papers on all aspects of electrochemistry of solid compounds, including experimental and theoretical, basic and applied work. It equally publishes papers on the thermodynamics and kinetics of electrochemical reactions if at least one actively participating phase is solid. Also of interest are articles on the transport of ions and electrons in solids whenever these processes are relevant to electrochemical reactions and on the use of solid-state electrochemical reactions in the analysis of solids and their surfaces.
The journal covers solid-state electrochemistry and focusses on the following fields: mechanisms of solid-state electrochemical reactions, semiconductor electrochemistry, electrochemical batteries, accumulators and fuel cells, electrochemical mineral leaching, galvanic metal plating, electrochemical potential memory devices, solid-state electrochemical sensors, ion and electron transport in solid materials and polymers, electrocatalysis, photoelectrochemistry, corrosion of solid materials, solid-state electroanalysis, electrochemical machining of materials, electrochromism and electrochromic devices, new electrochemical solid-state synthesis.
The Journal of Solid State Electrochemistry makes the professional in research and industry aware of this swift progress and its importance for future developments and success in the above-mentioned fields.
