Rational engineering of VS nanorod array on rose-shaped VS nanosheets for high-performance aluminium-ion batteries. | LitMetric
High performance aluminium-ion (Al-ion) batteries are of wide interest owing to the high theoretical capacity, abundance of Al metal and good safety. Here, we develop a hierarchical VS@VS composed of a VS nanorod array grown on VS rose-shaped nanosheets that displays a good electrochemical performance. The VS@VS cathode displays a high capacity of 162.7 mA h g after 200 cycles at -10 °C, and keeps 116.5 mA h g after 500 cycles at room temperature. Rate-performance at -10 °C shows a capacity retention rate of 90%, which indicates the potential for engineering high-performance energy-storage composites.
