Tesla Model 3 has the highest energy density of all models

Tesla claims that its car battery has one of the highest energy densities of any of its kind on the market and uses relatively little cobalt metal. Tesla designed the battery architecture for the Model3 model. It used the larger 2170 core and also cooperated with Panasonic to manufacture the battery at Tesla's Nevada Superplant 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, from the point of view of physical laws, it still seems to be open to question. The owner of Xuduotesila 3 tested the core and claimed that its energy density was 5,750to6 ,000 mAh, but this value has not yet 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.
