DOE: cobalt is the most expensive material used in lithium-ion battery cathodes

Green Car Congress

Aside from the lithium needed to produce modern lithium-ion batteries, much attention is focused on the cost of the materials used for EV battery cathode production. Cobalt is an important ingredient in lithium-ion battery cathode production, accounting for about a quarter of the cost of the battery.

UH, Toyota researchers develop new cathode and electrolyte for high-power Mg battery rivaling Li-ion

Green Car Congress

Magnesium batteries have long been considered a potentially safer and less expensive alternative to lithium-ion batteries, but previous versions have been severely limited in the power they delivered. Magnesium ions hold twice the charge of lithium, while having a similar ionic radius. —Dong et al. Tutusaus, O.,
