Bacteria instead of Lithium?

Bacteria battery by Sam Molenaar

Sam Molenaar believes that, with further optimization, the bacteria-based battery could rival the performance of lithium-ion batteries at a lower cost and with greater safety.

A rechargeable battery driven by bacteria? Lithium-ion batteries are limited by safety issues, high costs and other factors. Sam Molenaar and his colleagues from Wageningen University wanted to come up with a less expensive, more sustainable solution. 

The research team combined two separate microbial energy systems. One system used bacteria to form acetate from electricity, while the other one converted the produced acetate back into electricity. Read More
