McMaster Engineering researchers Emily Cranston and Igor Zhitomirsky are turning trees into energy storage devices capable of powering everything from a smart watch to a hybrid car.
The scientists are using cellulose, an organic compound found in plants, bacteria, algae and trees, to build more efficient and longer-lasting energy storage devices or supercapacitors. This development paves the way toward the production of lightweight, flexible, and high-power electronics, such as wearable devices, portable power supplies and hybrid and electric vehicles.
"Ultimately the goal of this research is to find ways to power current and future technology with efficiency and in a sustainable way," says Cranston, whose joint research was recently published in Advanced Materials. "This means anticipating future technology needs and relying on materials that are more environmentally friendly and not based on depleting resources.
