Researchers make a high-performance battery from junkyard scraps

Science_afficionado writes: A team of engineers and materials scientists at Vanderbilt University have discovered how to make high-performance batteries using scraps of metal from the junkyard and common household chemicals. The researchers believe their innovation could provide the large amounts of economical electrical storage required by the grid to handle alternative energy sources and may ultimately allow homeowners to build their own batteries and disconnect entirely from the grid.
