AI Article Synopsis
- Carbon-decorated NaV(PO) materials were created using a sol-gel method followed by heat treatment, with NVP@C-800 standing out in performance.
- NVP@C-800 showcased an impressive cycle life of 2000 cycles at a high rate of 10C, outperforming other materials and reports in existing literature.
- In a symmetric sodium-ion battery, NVP@C-800 demonstrated a high capacity, voltage plateau of 1.79 V, and an energy density of 113 W h kg, indicating its potential for future applications.
Article Abstract
In this work, several carbon-decorated NaV(PO) materials (NVP@C-750/800/850) are successfully fabricated using a sol-gel approach and subsequent heat treatment. When NVP@C-800 is used as a cathode, it shows an ultralong cycle life (2000 cycles) at a high rate of 10C, which is superior to the other two electrodes and those of reported NVP@C cathodes in the literature. The excellent results of NVP@C-800 are attributed to its nanostructure and the well-defined conductive carbon layer. The symmetric sodium (Na)-ion battery (SIB) with NVP@C-800 as both a cathode and an anode shows a high capacity at 40 mA g with a voltage plateau of about 1.79 V and energy density of 113 W h kg, revealing that NVP@C is of great application prospect.
