Fractal electrode prototype could revolutionize energy storage

A study published in Nature showed that embracing the structure of fractal Fern leaves, is a possible new and better way to store Solar energy. Today, solar energy is stored in battery banks. Researchers are working on using supercapacitors to do the same thing, but the energy density is restricted which limits the storage.

By using a fractal fern leave structure, the ratio of the relative active area compared to the volume can be increased, which reduces the electrolyte ionic path. This results in a 30 times higher energy density within the supercapacitators compared to the current way of using supercapacitors.

According to the researchers, energy storage with these fractal electrodes opens the prospects of efficient self-powered and solar-powered wearable, flexible and portable applications. Read the full article here
