Why does Tesla use cobalt?

As cobalt protects the cathode from corrosion, reducing its content in batteries could slash the life cycle of the battery cell. Their new range of 4680 batteries intended for the new generation of Tesla cars do not use nickel-manganese-cobalt cathode but a high-nickel cathode.

Why do we need cobalt 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.

How much cobalt does an electric car use?

Cobalt is considered the highest material supply chain risk for electric vehicles (EVs) in the short and medium term. EV batteries can have up to 20 kg of Co in each 100 kilowatt-hour (kWh) pack. Right now, Co can make up to 20\% of the weight of the cathode in lithium ion EV batteries.

Is there cobalt in Tesla batteries?

For instance, Tesla’s current vehicle batteries contain less than five percent cobalt and the company announced in September 2020 that they are developing their own batteries that will be cobalt-free.

What can replace cobalt?

Cobalt is toxic, expensive, and deeply entrenched in unethical mining practices — it is a major roadblock in the transition to electric vehicles (EVs). But the lithium ion battery industry can move towards a future-friendly alternative: manganese.

Does Apple use cobalt?

Apple, one of the world’s biggest users of cobalt, is believed to have first opened talks with miners over a year ago in a bid to avoid getting caught out by potential future shortages of the raw material. The company uses cobalt to power many of its gadgets, including the iPhone and iPad.

Is lithium used in electric cars?

The most common battery type in modern electric vehicles are lithium-ion and lithium polymer, because of their high energy density compared to their weight.

What does Elon Musk use cobalt for?

Tesla CEO Elon Musk has pointed the accusatory finger towards Apple and said the electronics giant is guilty of using cobalt in the batteries that are then fitted into gadgets. At the same time, Musk also painted a favourable image for Tesla and said the batteries made use of by the EV company hardly uses any cobalt.

Does Tesla use cobalt mines?

In 2020, Tesla secured a deal with Swiss mining giant Glencore. Although Glencore gets most of its cobalt from the DRC, Tesla has stipulated in its contract that suppliers use “conflict-free” minerals.
