Viruses the new material for Li-ion batteries

Scientists at MIT have displayed that genetically engineered viruses could work as the cathode and the anode of lithium ion batteries. Success in creating the anode from viruses came early, but creating a highly conductive cathode proved to be the difficult part. Researchers came around this problem by genetically engineering viruses to coat themselves with iron phosphate, and then get hold of carbon nanotubes. This provided a highly conductive cathode for the battery.

The new technology allows for more powerful, lightweight, flexible batteries that can take the shape of their container. With success at this stage, scientists intend to create a second generation of virus batteries, using manganese phosphate and nickel phosphate. The second generation batteries will be able to provide a higher voltage, and could be ready for production.
