Battery scientists from Sweden could borrow some packaging tips from Colgate as they develop an amazing unit with fluid electrodes. The malleable breakthrough could transform energy storage for gadgets, according to the Linköping University research team.
“The texture is a bit like toothpaste,” Assistant Professor Aiman Rahmanudin said in a news release. A photo shared by the team shows a dark, pasty substance being squeezed from a tube. If it were white, it would fit the visual billing for your typical tooth cleaner.
The fluid electrode opens the door for fascinating production potential.
“The material can, for instance, be used in a 3D printer to shape the battery as you please,” Rahmanudin added.
When common lithium-ion batteries charge and discharge, ions move between…
