Scientists use virus to help build battery

Scientists at the Massachusetts Institute of Technology have demonstrated how a genetically modified virus can be used to construct both the cathode and anode of a lithium ion battery.

Virus-built rechargeable batteries would have the same power capacity as the batteries used to power hybrid cars, project leader professor Angela Belcher said in an MIT press statement on Thursday.

In a paper published in the journal Science, the research team explained that it manipulated two genes of the M13 virus to equip the bacteriophage with peptide groups that attract single-walled carbon nanotubes at one end, while the other end of … Read more
