Scientists use virus to build a better 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 they 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 the virus was equipped with peptides that nucleate amorphous iron phosphate.
Combining the nanotubes with the iron phosphate created a highly conductive material that was used in a cathode, said the MIT statement. Battery energy was transferred in "a very short time", as electrons could travel along the carbon nanotube networks and percolate throughout the electrodes.
Is Mankind the Virus?:O
Go there...
