Plastic bag batteries

Sunday, December 20, 2009

Scientists have come up with yet another way to upcycle plastic bags, this time into nanotubes that can be used to make batteries. According to Discover magazine, however, it’s a pricey process.

It involves an expensive catalyst in cobalt acetate, which is not easily recovered, to convert the high or low-density polyethylene (HDPE and LDPE) into carbon nanotubes. But if the nanotubes are then used to make lithium-ion or lithium-air batteries, that might overcome this problem, since these batteries are already recycled at the end of their use to recover cobalt.
