In an effort to develop a more affordable, plentiful alternative to lithium-ion batteries, researchers from Purdue University are pursuing rechargeable potassium based batteries, demonstrating a way to derive carbon for battery electrodes from old tires.
“With the growth of rechargeable batteries for electronic devices, electric vehicles and power grid applications, there has been growing concern about the sustainability and cost of lithium,” says Vilas G. Pol, an associate professor in the Davidson School of Chemical Engineering at Purdue University and former member of ECS. “In the last decade, there has been rapid progress in the investigation of metal-ion batteries beyond lithium, such as sodium and potassium.”
Researchers in the field believe that potassium based batteries show potential for large-scale grid storage due to their low cost and the abundance of the element itself.
“The intermittent energy generated from solar and wind requires new energy storage systems for the grid,” Pol says. “However, the limited global availability of lithium resources and high cost of extraction hinder the application of lithium-ion batteries for such large-scale energy storage. This demands alternative energy storage devices that are based on earth-abundant elements.”

Science is messy, but it doesn’t have to be dirty.
On June 21, publishing giant Elsevier won a legal judgement against websites like Sci-Hub, which illicitly offer access to over 60 million academic articles. The court ruled in Elsevier’s favor, awarding the publisher $15 million in damages for copyright infringement.
Using energy stored in the batteries of electric vehicles to power large buildings not only provides electricity for the building, but also increases the lifespan of the vehicle batteries, new research shows.
