Scientists have developed what they call a biobattery that is powered by sugar — it converts the chemical energy stored in sugar substrates into electricity.

"We are the first to demonstrate the complex oxidation of the biobattery's sugar, so we achieve a near-theoretical energy conversion yield that no one else has reported," said Y H Percival Zhang, chief science officer of Cell-Free BioInnovations (CFB) at Virginia Tech.

The battery itself is a enzymatic fuel cell (EFC), which is an electrobiochemical device that can convert chemical energy from starch and glycogen. The enzymes in these materials can create more complex fuels, like glucose, which provides EFCs with better energy density. 

According to International Business Times, sugar has more potential energy that lithium-ion batteries. The sugar biobattery can store 15 times more energy than lithium-ion and can run 10 times longer. 

Additionally, a battery made of sugar is much more environmentally friendly, is not flammable and is much cheaper to manufacture.
