Abstract

In this article, the structure and electrochemical performance of sodiated iron phosphate (FePO4) synthesized by the micro-emulsion technique have been investigated by X-ray diffraction (XRD), high resolution transmission electron microscopy (HRTEM) and electrochemical measurement. The results reveal that amorphous FePO4 could be transformed into crystallite sodium iron phosphate (NaFePO4) during electrochemical sodiation. Furthermore, the results of electrochemical testing show that the initial specific-discharge capacity of FePO4 is 142 mA h g−1, and it still delivers a reversible capacity of 130.8 mA h g−1 after 120 cycles. The discharge capacities could attain values of 142 mA h g−1, 119.1 mA h g−1, 91.5 mA h g−1 and 63.5 mA h g−1 at 0.1 C, 0.2 C, 0.5 C and 1 C, respectively. These findings have indicated that NaFePO4 has been formed during the electrochemical process and that amorphous structured FePO4 is one of the most promising “host” materials.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
