Water-based batteries promise organic charging
Had to mention this one. We’ve just had fire (see Pelty powers Bluetooth speakers with fire), and now here’s water! An eco-friendly, water-based organic battery, to be precise.
Scientists at University Southern California have been working on the new battery forms that use no metals or toxic materials.
“The batteries last for about 5,000 recharge cycles, giving them an estimated 15-year lifespan,” said Sri Narayan, professor of chemistry at the USC Dornsife College of Letters, Arts and Sciences.
“Lithium ion batteries degrade after around 1,000 cycles, and cost 10 times more to manufacture.”
As well as being long-lasting, and cheap, they are aimed use in power plants, where they could apparently make the energy grid more resilient and efficient.
