Tesla: Model 3 batteries have

The US electric car manufacturer Tesla has published some interesting details about the battery cells of the Model 3. According to this, the batteries in Tesla’s compact electric vehicles designed for the mass market should offer the highest energy density on the market and contain significantly less of the conflict raw material cobalt than previous battery technologies.

The Tesla Model 3 uses the latest generation of 2170 lithium-ion cells, which the car manufacturer has been producing together with its battery partner Panasonic since June 2017 in Gigafactory 1 in Nevada. Tesla works closely with the Japanese manufacturer to perfectly match the chemistry of the cells to their area of application.

In Tesla‘s shareholder letter released a few days ago, the company divulged some details about the Model 3’s battery cells. Accordingly, the cells offer “the highest energy density used in an electric vehicle”. Tesla has achieved this by significantly reducing the cobalt content per battery pack while increasing the nickel content. The cobalt content is already lower than next-generation cathodes being developed by other cell manufacturers. This also put the weight of the Model 3 on par with its petrol-powered counterparts, according to Tesla.

The demand for cobalt has increased significantly in recent years, prices have multiplied. Cobalt is used in various types of battery cells, and the demand for battery cells has increased greatly due to the rise of electric cars and energy storage systems, as well as smartphones and laptops, among others.

Tesla’s CTO JB Straubel added that his company recognized the trend early and has been “on track to reduce cobalt consumption” for several years. Tesla has not commented on the costs per kWh for the Model 3. The industry standard was reportedly around $225 per kWh last year. Tesla already claimed to be under $190 per kWh at the time. Tesla’s CFO Deepak Ahuja said that Tesla batteries are “best in class in terms of cost per kWh”.

Experts have already suspected that particularly powerful and inexpensive battery cells are used with Tesla’s electric truck Semi.

  1. Well, it’s no wonder that the E Auto Pioneer is also at the forefront when it comes to battery technology. If you don’t get any e-car sales figures on the line, you have no interest in building the best batteries because of the lack of pressure. Only the progress of battery technology and the pace of improvement is still far below that
    of mobile phones. Namely with increased performance of storage, range, weight and price. But it is
    assume that they will always come out on top of top dogs Toyota, Tesla, GM, Renault and the Koreans.
    One can only advise European start-ups to join forces quickly in the 40/50 KW battery sector, where the affordable mass market will open up, to procure storage.

  2. How high is the energy density (Wh/kg) of the Tesla batteries and what does 1 kg of the Tesla batteries cost ?

  3. Tesla has reported that the batteries cost less than $100 to manufacture! That’s almost 93 euros per kWh!

  4. Here is the statistical evaluation of the price development for rechargeable batteries:


    Not yet priced in here are psychological developments in the markets due to completely new technologies and their spread, which will result in a reduction in margins in favor of customers, such as e.g.B. the introduction of solid-state batteries or other cheap raw materials (silicon, etc.).etc.), which should already play a role in 2020.
