How does Tesla use cobalt?

Tesla will make electric vehicle batteries with cobalt-free cathodes, it announced during its Battery Day event today. Cobalt is the most expensive material used in batteries, so eliminating it from the mix was expected help to electric vehicles become as affordable as those that run on gas.

Can batteries be made without cobalt?

In July, a team of three researchers from the University of Texas reported the results from tests using a new cathode chemistry that eliminates cobalt entirely. They used their nickel-rich cathode in a small experimental lithium-ion pouch cell about the size of a deck of cards.

Can cobalt be made?

Today, some cobalt is produced specifically from one of a number of metallic-lustered ores, such as cobaltite (CoAsS). The element is, however, more usually produced as a by-product of copper and nickel mining….
