Gallery: Algae Could Be the Key to Ultra-Thin Biodegradable Batteries


Algae is often touted as the next big thing in biofuels, but the slimy stuff could also be the key to paper-thin biodegradable batteries according to researchers at Uppsala University in Sweden. Eventually, the bio batteries could compete with commercial lithium-ion batteries.

    Algae is already being developed into biofuel, but it’s neat to see new applications with paper-thin biodegradable batteries. If you’re interested in alternative energies or green technologies, check out It has hundreds of case studies on emerging green technology. It’s also the largest b2b green directory on the web.

    I am totally interested in learning more about algae battery technology. Would this not also reduce the number of trees used in paper batteries?

    This is good news- too often, engineering with algae is discussed in the context of using it to produce bio-fuels. The entire idea of bio-fuels, I think, is really just a subterfuge for the desire of politicians to do nothing.

    It’s great that they can make good batteries out of the stuff, especially because better batteries are one of the chief technical hurdles we have to clear to solve the intermittency problems of solar and wind energy.
