Electric battery
A new battery material could offer a more sustainable way to power electric cars. The lithium-ion battery includes a cathode based on organic materials, instead of cobalt or nickel.
The lithium-ion (Li-ion) batteries that power most EVs are their single most-expensive component, typically representing some 40% of the price of the vehicle …

Batteries for Electric Vehicles
This research demonstrated an approach where long-lived beta-emitting radioisotopes can be used to match the power density (the ability to release power) of chemical batteries while surpassing them in energy density (the ability to store power). Researchers investigated how the converter geometry and beta-conversion can influence …
"In our paper, we outlined the mechanics of materials for solid-state electrolytes, encouraging scientists to consider these when designing new batteries." Reference: "Solid-state batteries: The critical role of mechanics" by Sergiy Kalnaus, Nancy J. Dudney, Andrew S. Westover, Erik Herbert and Steve Hackney, 22 September 2023, …
