In this meeting, when discussing Tesla how to further expand the relationship with the partner Panasonic, Musk to the participants highlighted the new battery and its potential value. Maske then said in a clarification statement, he said that this battery "has the world's best energy density."
Maske's statement is a bold approach, but not a surprise. Because Tesla had to make a compromise, to choose to use an expensive, high energy density of the solar powered portable generator battery; or the use of low-cost, energy density is relatively low battery. The current Tesla Model X and Model S electric vehicle battery pack, is from the Panasonic Corporation's 18650 battery unit. The 18650 battery (also referred to as 18-650) has a diameter of 18 mm and a length of 65 mm. The 2170 battery (or 21-70) also follows the same design logic, with a diameter of 21 mm and a length of 70 mm.
The 18650 battery currently used in Tesla's existing electric vehicle products has an estimated energy density of approximately 250 Wh / kg (Watts / kg). Earlier this year, Tesla officially said its battery packs on Model S electric vehicles cost less than $ 190 a kilowatt-hour. The Electrek website estimates that the cost of this battery pack should be between 100-150 US dollars / kWh, the final cost depends on the size of the electric vehicle lifepo4 battery pack. For the 2170 battery, Maske did not provide any details of the cost-related to the outside world.
Although Maske did not mention which electric cars will be equipped with this new battery, but the possibility of a larger assumption, 2170 battery will be the first application of the upcoming Model 3 electric vehicles on the market. In view of Tesla past development history and continuous updates, the future in the Model S and Model X electric vehicles equipped with this battery will also be very possible.
