From trees to power: Engineers build better energy storage device

New work demonstrates an improved three-dimensional energy storage device constructed by trapping functional nanoparticles within the walls of a foam-like structure made of nanocellulose. The foam is made in one step and can be used to produce more sustainable capacitor devices with higher power density and faster charging abilities compared to rechargeable batteries. This development paves the way towards the production of lightweight, flexible, and high-power electronics for application in wearable devices, portable power sources and hybrid vehicles.
