CeNS scientists developed an oxygen-deficient bimetallic oxide (Mo_(0.11)W_(0.89)O_(3-x)) that stores energy and visually indicates charge level through color change.
The material demonstrated high optical modulation of 43% at 700 nm with coloration efficiency of 147 cm² C⁻¹ for electrochromic applications.
As a supercapacitor electrode, it showed specific capacitance of 234 F g⁻¹ and areal capacitance of 975 mF cm⁻² with excellent cycling stability of 10,000 cycles.
The device successfully powered an LCD timer and LED while maintaining functionality under mechanical bending and environmental stress.
