Tesla has announced that Model 3 battery details have the highest energy density in the industry

According to foreign media reports, Tesla claims that the energy density of its car battery is at the forefront of all similar products on the market, and the amount of cobalt metal used in this battery is relatively small. Tesla designed the battery structure for the Model3 model, which uses a larger 2170 battery core and also worked with Panasonic to manufacture the battery at Tesla's Nevada Super Factory No. 1.

Tesla mentioned the details of the Tesla Model 3 battery in an e-mail to shareholders yesterday (May 3, 2018), as follows:

"Tesla Model 3's core has the highest energy density in all models. The company has significantly reduced cobalt content while increasing nickel content and maintaining excellent thermal stability, which in turn has increased energy density. The chemical ratio of the nickel-Cobalt-Aluminum battery cathode has been lower than that of other core manufacturers. The latter's battery cathode uses nickel-Manganese-Cobalt. The ratio is 8:1:1. For this reason, even with the battery, the Model 3's gross weight is comparable to that of a gasoline car. "

Although Tesla has repeatedly emphasized that its energy density ranks first in the industry, it seems to be still open from the perspective of physical laws. Many Tesla Model3 owners have tested batteries, claiming an energy density of 5,750 to 6,000 mAh, but this value has not been demonstrated.

Tesla reduced the cobalt content in the cathode of the battery, perhaps because the price of cobalt metal has more than doubled in the past year. As the chemicals of all types of batteries are inseparable from cobalt, the demand for cobalt has also increased significantly. Batteries and energy storage systems are bound to use cobalt metal.

The cost of electric car batteries fell to $227/kWh last year, according to a report, and Tesla claimed its battery cost was lower than $190/kWh. According to industry estimates, only when Tesla's battery cost falls below $100 / kWh can it benefit Tesla Semi's pricing and help Tesla Model 3 achieve profitability.
