There has been a new invention recently in the USA. Some researchers from the Virginia Technology College of Agriculture and Life Sciences have created a new kind of battery: a sugar battery. The sugar-powered battery could replace the traditional lithium-ion batteries that have been used for decades. The scientists who created it claim that this new technology can store 10 times more energy than traditional equivalent size batteries found in smartphones. Moreover, the sugar batteries are cheaper, refillable and environment friendly, as they are biodegradable.
