Why is cobalt used in batteries?

The cobalt in these batteries has a stabilizing effect and prevents cathode corrosion that can lead to a battery fire. It can also boost a battery’s charge rates, but the raw material is pretty expensive and hard to come by.

Why is nickel so good for batteries?

The major advantage of using nickel in batteries is that it helps deliver higher energy density and greater storage capacity at a lower cost. It is making energy production from intermittent renewable energy sources such as wind and solar replace fossil fuels more viable.

How does Tesla get cobalt?

Tesla sources most of its cobalt from the Democratic Republic of Congo (DRC), which has been beset by claims of illegal mining, human rights abuses and corruption.
