An associate professor of biological systems engineering Y. H. Percival Zhang, leading the research team at Virginia Tech’s Agriculture and Life Sciences and College of Engineering, developed a battery run by natural sugar. It can replace the typical batteries we normally use in daily life. Its life span is around three years!
While this not the first time sugar batteries have been developed, Zhang claims his prototype has an energy density of a higher order of magnitude than others, which allows it to run longer before needing to be refueled.
The sugar batteries comprise of fuel, in this case maltodextrin, a polysaccharide made from partial hydrolysis of starch. Such element and air can generate electricity, and water is its main byproduct.
“We are releasing all electron charges stored in the sugar solution slowly step-by-step by using an enzyme cascade,” Zhang added.
