Sugar Batteries Could Store 20% More Energy Than Li-Ions

Posted by timothy on from the sweet-deal dept.

An anonymous reader writes "Scientists at the Tokyo University of Science have developed a way to create sugar batteries that store 20% more energy than lithium-ion cells. Before it can be used as the anode in a sodium-ion battery, sucrose powder is turned into hard carbon powder by heating it to up to 1,500 degrees celsius in an oxygen-free oven." Except that swapping batteries might be a bit tricky, I can think of a perfect application for these.

    But it could create one. Like it did with corn.

    Oh, and btw mods, "overrated" and "flamebait" are not "I disagree"

    Thanks.
