Recycling Lithium-ion Batteries

How On Earth radio | December 22, 2020

Our lives have been changed by lithium-ion (Li-ion) batteries which are everywhere: in our cell phones, cars, toys, power tools and grid energy storage. As the world manufactures more and more Li-ion batteries, what are the challenges and opportunities for recycling them? How can we prevent the batteries from ending up in landfills where the toxic metals inside can leak out? In this episode, we talk with Dr. Zheng Chen, a professor of nanoengineering at the University of California San Diego. Full Story


Disordered rock salt makes fast-charging anode for li-ion batteries

Electronics Weekly | September 8, 2020

Researchers at UC San Diego have developed a new anode material that enables lithium-ion batteries to be safely recharged within minutes for thousands of cycles. Full Story


Disordered Rock Salt And Transition Metal Anodes-- Engineering The Batteries Of The Future

CleanTechnica | September 4, 2020

People like to say nothing is sure but death and taxes. But there is something else we can be sure of ? announcements about blockbuster new battery technologies that promise higher energy density and shorter charging times. Given that discoveries in the lab usually take years to make their way into production, two such announcements this week suggest the children of tomorrow will think about today?s lithium-ion batteries the way children today think about transistors.

Could 'disordered rock salts' bring order to next-gen lithium batteries?

Ars Technica | September 4, 2020

Earlier this week, a paper covers a new electrode material that seems to avoid the problems that have plagued other approaches to expanding battery capacity. And it's a remarkably simple material: a variation on the same structure that's formed by crystals of table salt. While it's far from being ready to throw in a battery, the early data definitely indicate it's worth looking into further. Full Story


Rocksalt anode can lead to safer, fast-charging Li-ion batteries

Hindu Business Line | September 3, 2020

The rocksalt anode helps achieve a crucial middle ground, which is safer to use than graphite, yet offers a battery with at least 71 per cent more energy than lithium titanate. Full Story
