Harnessing the Power of Viruses

Researchers at MIT have genetically engineered viruses to build the positively and negatively charged ends of a lithium ion battery. With the same energy capacity and power performance as state-of-the-art rechargeable batteries, they could be used to power plug-in hybrid cars and a range of personal electronics.

For the cathode, these genetically engineered viruses are built to coat themselves with iron phosphate, then self-assemble onto carbon nanotbues to create a network of highly conductive material. These viruses are a common bacteriophage, which infect bacteria but art harmless to humans.

Part of a recent wave of clean-energy technologies, these battery prototypes are lightweight, flexible, and pending commercial production.
