Fast ‘green’ process revives essential battery components for reuse. How many rechargeable lithium-ion batteries are you wearing? How many are in your general vicinity?
Probably more than a few, and they’re great for powering all the things important to modern lives: cellphones, watches, computers, cars and so much more.
But where they go when they fail is a growing problem. Rice University scientists believe they have a partial solution that relies on the unique “-flash” Joule heating process they developed to produce graphene from waste.
The Rice lab of chemist James Tour has reconfigured the process to quickly regenerate graphite anode materials found in lithium-ion batteries, removing impurities so they can be used again and again.
The lab’s work appears in Advanced Ma...
