2019/5/1Potassium-ion batteries (PIBs) have attracted tremendous attention due to their low cost, fast ionic conductivity in electrolyte, and high operating voltage. Research on PIBs is still in its infancy, however, and achieving a general understanding of the drawbacks of each component and proposing research strategies for overcoming these problems are crucial for the exploration of suitable

Frontiers

2018/8/17Aqueous battery has been gained much more interest for large-scale energy storage fields due to its excellent safety, high power density and low cost. Cryptomelane-type KMn8O16 confirmed by X-ray diffraction (XRD) was successfully synthesized by a modified hydrothermal method, followed by annealed at 400C for 3 h. The morphology and microstructure of as-prepared KMn8O16 investigated

Electrochemically mediated deionization: a review

1. Introduction As a result of rapid population growth and global development, the lack of clean and accessible water has become a critical international concern. 1 A small fraction of the earth's water is freshwater and much of this supply is inaccessible: 1% of all the water on the planet is readily available for human use. 2 Some arid, coastal and arctic regions are geographically limited

2019/5/22Furthermore, Hong et al. [] investigated the performance of potassium nickel hexacyanoferrate in organic electrolytes and reported that this cell can achieve a reversible discharge capacity of 55.6 mAh g −1 at a rate of 0.2 C with a discharge voltage at 1.19 V (vs

Electrochemically anchored manganese hexacyanoferrate

2020/2/15Taking value of this superior architecture, we demonstrate a three-dimensional (3D) reduced graphene oxide-supported manganese hexacyanoferrate (MnHCF/rGO) hybrid electrode. Firstly, a 3D conductive rGO scaffold is constructed via electrophoretic deposition (EPD) of graphene oxide nanoplatelets (GONPs) on graphite substrate and a subsequent electrochemical reduction to enhance

Reduced Graphene Oxide

Low-cost manganese hexacyanoferrate (NMHCF) possesses many favorable advantages including high theoretical capacity, ease of preparation, and robust open channels that enable faster Na+ diffusion kinetics. However, high lattice water and low electronic conductivity are the main bottlenecks to their pragmatic realization. Here, we present a strategy by anchoring NMHCF on reduced graphene oxide
