Washington: Scientists have developed a battery that uses sugar to generate electricity enough to power a smartphone for 10 days. The bio-battery designed by researchers at Virginia Polytechnic Institute and State University has a greater output per weight than the typical lithium ion batteries used in most electronic gadgets. The prototype has the potential to be lighter and more powerful than the batteries typically found in today’s portable electronic devices, including smartphones. In the body, sugar is converted into energy in a process called metabolism, which decomposes sugar into carbon dioxide and water while releasing electrons. Bio-batteries produce energy though the same conversion process by capturing the electrons that are generated in the decomposition of sugar with the same tools that the body uses. As bio-batteries use materials that are biologically based, they are renewable and non-toxic, making them an attractive alternative to traditional batteries that need metals and chemicals to operate. “By using the lithium ion batery, for example, your phone can only last for one day, but in the future it will use sugar as fuel and then the phone could last 10 days,” said Zhiguang Zhu, a researcher at Virginia Tech.
The new bio-battery gets its efficiency by using a unique system based on enzymes, which are proteins that help the reaction to take place. AGENCIES
