Transition to electric vehicles could create unwanted air pollution hotspots in China and India
Credit: Princeton University, Bumper DeJesus Electric vehicles are a cornerstone of the global energy transition, but a new Princeton University-led study finds that refining critical minerals needed for electric vehicle batteries could create pollution hotspots near manufacturing sites. It has been proven that there is. Researchers focused on China and India and found that if these countries fully domesticated their…

Scientists develop new model of electric double layer
Credit: CC0 Public Domain The new model takes into account a wide range of ion-electrode interactions and predicts the charge storage capacity of the device. The model’s theoretical predictions are consistent with the experimental results. Data on electric double layer (EDL) behavior can help develop more efficient supercapacitors for portable electronics and electric vehicles. The study was published in ChemPhysChem.…

Researchers have solved a key problem with sodium-ion batteries for electric vehicles and grid energy storage
Artistic rendering of the important discovery that lowering the heating rate during the fabrication of cathodes in sodium-ion batteries eliminates the problem of distortion and cracking in core-shell particles with concentration gradients. Credit: Argonne National Laboratory. Lithium-ion batteries have long dominated the market as the go-to power source for electric vehicles. Consideration is also underway to store renewable energy for…
