Bamboo-like Carbon Nanofibers for Flexible Supercapacitors

Using bamboo inspired carbon nanofibers, Stanford researchers at the Yi Cui Lab have created a freestanding, flexible and elastic electrode for energy storage devices. This mechanically durable membrane has excellent mechanical and electrochemical properties, and provides a high surface area accessible to the electrolyte and low ion-transport resistance, key attributes in flexible energy storage for flexible electronics. Without the need for extra support, the volumetric energy and powder densities based on the whole device surpass state-of-the-art devices.
Even under continuous dynamic operations of forceful bending (90°) and twisting (180°), the as-designed device still exhibits stable electrochemical performances with 100% capacitance retention. Such a unique supercapacitor holds great promise for high-performance flexible electronics
