Flexible, ultralight, and high-energy density electrochemical capacitors using sustainable materials

Development of flexible, ultralight, scalable and non-leaking energy storage devices such as electrochemical capacitors that are on par with commercial standards and offer compliances while retaining safety remain a significant challenge for the realization of wearable devices. Generally, the bottle...
