Big EV giant Tesla is planning to stop using cobalt in their vehicles. This element is a major part in building an electric vehicle, and it is an expensive part to acquire. It is one of the reasons why electric vehicles cost a lot. Even though electric cars have good long-term effects, it is definitely costly at first. This is one of the reasons there aren’t that many EVs cruising down the highways.
Lithium-ion batteries are currently the ones being used in typically electric-powered cars. One of its components is cobalt, which contributes to its energy density, a measure of an electric car’s mileage in a single charge. Cobalt amounts to about 40% of the car’s total price. It also has many issues surrounding its procurement.
But Tesla is about to make a revolutionary change in the EV game by turning its back on cobalt-using lithium-ion batteries and applying the new lithium-iron. Its primary goal is to reduce the total manufacturing price of an EV by producing a cobalt-free battery.
This early venture by Tesla seems to be a smart move, as the supply of cobalt runs low and the price to obtain it is predicted to rise in the following years. By that time, not only EV makers will be affected, but all other battery manufacturers as well. Cobalt is also an unsustainable energy source, and has negative effects to the environment.
Lithium-iron is currently being developed by a Chinese battery manufacturer Contemporary Amperex Technology (CATL) and Tesla has partnered up with them in the production of said batteries that will soon power new Tesla EV models. CEO Elon Musk is determined to make this innovation a reality while still maintaining Tesla’s integrity and even opting for improved performance.
