Cell-Sized Batteries are Arriving
In the Proceedings of the National Academy of Sciences (PNAS) the week of August 18, the MIT team describes assembling and successfully testing two of the three key components of a battery. A complete battery is on its way.
“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.
