| Abstract Scope |
Nano-scale materials are considered promising for realization of high performance electrochemical energy storage (EES). In contrast, the inadequate ion-accessible surface area of existing nano-textured electrodes limits their overall performance. Herein, we provide the first demonstration of solid-state nano-moulding in a crystalline alloy, resulting in a highly ordered hierarchical nano-tubular architecture with outstanding electrochemical energy storage. Benefitting from increased material fluidity at high strain-rate, a short-burst of physical deformation facilitated the material flow into the nano-moulds. The chemically dealloyed nano-tubular electrode demonstrated excellent volumetric specific capacitance of ~ 1000 F/cm3 at 5.5 A/cm3 current density. A symmetric supercapacitor device showcased outstanding energy density of ~ 90 Wh/L at power density of ~ 0.5 kW/L along with excellent cyclic stability of 94% after 10,000 cycles. The device-level technology readiness is demonstrated by successfully integrating multiple small devices to operate high-power electronic components, setting the way forward for advanced energy storage applications. |
