WO3−x/MoO3−x Core/Shell Nanowires on Carbon Fabric as an Anode for All‐Solid‐State Asymmetric Supercapacitors

Owing to the rapidly growing global energy consumption, the development of high-performance power sources has become an urgent and increasing demand in various fi elds such as portable electronics and sensor networks. [ 1–3 ] As a result of their excellent characteristics, such as superior power density, fast charge/discharge rates, and long cycle lifetime, supercapacitors (SCs, also known as electrochemical capacitors or ultracapacitors), which bridge the gap between high specifi c energy batteries and high specifi c power conventional capacitors, have been employed as state-of-the-art energy storage systems and widely used in consumer electronics, backup power sources, and pacemakers.
