Green Algae Batteries
Thanks to the efforts of some people over at Uppsala University in Sweden, we may yet address the power problems with these new paper-thin batteries made from celulllose produced by Cladophora or green algae. These Cladophora specimens are found in beaches and produce cellulose with an unusually large surface area. These algae cellulose can hold up to 50 to 200 percent more charge than similar conducting polymer batteries, and may someday compete with commercial lithium batteries.
Charge times could also trump today’s rechargeables – the researchers managed to recharge their test batteries in anywhere from 8 minutes down to as little as 11 seconds. Combining their thinness and new found energy, these batteries can certainly be welcome additions to the growing need for batteries which are seen as the next big demand to date.
