Tesla reveals the details of the Model 3 battery energy density is the most advanced level in the industry

Introduction: The energy density of the batteries used in the Tesla Model3 ranks first in all models. The company has significantly reduced the cobalt content, while increasing the nickel content, maintaining excellent thermal stability and thus increasing the energy density.

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 Model3 battery in an email to shareholders yesterday (May 3, 2018), as follows:

“The energy density of the batteries used in the Tesla Model3 ranks first in all models. The company has significantly reduced the cobalt content, while increasing the nickel content, maintaining excellent thermal stability and thus increasing the energy density. Nickel-cobalt aluminum (Nickel) -Cobalt-Aluminum) The cathode ratio of the battery cathode is lower than that of other cell manufacturers. The cathode of the latter uses a ratio of nickel magnesium cobalt (nickel manganese cobalt) of 8:1:1. Therefore, even if you count the battery, the gross weight of the Model3 can match the 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 5750 - 6000mah, 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. Since the chemical substances of various types of batteries are inseparable from cobalt, the demand for cobalt also shows a significant increase, and cobalt and metal are bound to be used in batteries and energy storage systems.

According to a report, the cost of electric vehicle batteries fell to $227/kWh last year, and Tesla claimed that its battery cost was less than $190/kWh. According to industry estimates, only when Tesla's battery cost price drops below $100/kWh can it benefit Tesla's pricing and help Tesla Model3 achieve profitability.
