Abstract:
Developing high-performance cathode materials for magnesium (Mg) batteries is of great significance. Here, a novel rose-with-thorn ternary MoS2@C@polyaniline (PANI) nanocomposite composed of carbon and PANI nanoneedles co-coated on rose-like MoS2 is developed. The conductive PANI needles on the surface of MoS2 improve the conductivity, and the inner MoS2 is wrapped by a carbon layer which is beneficial for the aniline coating. The MoS2@C@PANI-based Mg battery cathode displays a good capacity of 114 mA h g-1 after 100 cycles, and a recoverable rate-performance after repeated measurements. In addition, a stable capacity of 105 mA h g-1 when cycled at a low temperature of -5 °C is also achieved, indicating good potential for applications.
