Report request: I am a researcher interested in cleaner alternatives to electrical vehicle batteries that avoid mining "dirty" materials like lithium or cobalt.
I would like a report detailing recent developments in battery technology that are applicable to powering electric vehicles. I am interested in cleaner technologies than those requiring lithium or cobalt mining, including, but not limited to, batteries based on sodium, aluminum, nickel, or potassium. I am specifically interested in production of such batteries at industrial scale while minimizing environmental concerns and manufacturing costs.
