Researchers at Japan’s Tohoku University have developed a special type of porous carbon sheet which significantly improves the energy density and cycle stability in lithium-air batteries.
Miners operating in Europe say prospects for getting projects underway look uncertain because of a lengthy permitting framework and fervent local opposition.
To win the full credit, EV makers have to source in 2023 at least two-fifths of battery materials from the US or free trade agreement partners such as Canada, Chile and Australia or recycle it in North America.
Based on a comparison of one of the most promising solid-state batteries to lithium-ion technology and using sustainable lithium sources, a battery's carbon footprint could be cut by as much as 39%.
