In a surprise development that could have implications for powering electronics, cars and even the military, researchers at MIT have created the world's first batteries constructed at the nano scale by microscopic viruses.
A much-buzzed-about paper published in the Proceedings of the National Academy of Sciences earlier this month details the team's success in creating two of the three parts of a working battery—the positively charged anode and the electrolyte. But team leader Angela Belcher told PM Wednesday that the team has been seriously working on cathode technology for the past year, creating several complete prototypes.

"To our knowledge, this is the first instance in which microcontact printing has been used to fabricate and position microbattery electrodes and the first use of virus-based assembly in such a process," wrote MIT professors Paula T. Hammond, Angela M. Belcher, Yet-Ming Chiang and colleagues.
Further, the technique itself "does not involve any expensive equipment, and is done at room temperature," said Belcher, the Germeshausen Professor of Materials Science and Engineering and Biological Engineering.
