Tesla CEO: 50 percent more battery energy density in three to four years-tesla

For months, Tesla boss Elon Musk has been luring investors and competitors with the promise of presenting groundbreaking advances in battery technology at a “Battery Day”. Tesla battery supplier Panasonic only recently got ahead of it, announcing a 20% increase in the energy density of “2170” battery cells in five years, as well as the fact that a cobalt-free version will be available “in two to three years”. But Musk wouldn’t be Musk if he didn’t have something up his sleeve.

Nevertheless, it also curbed expectations of Tesla’s “Battery Day” for a short time, but at least put it a step ahead compared to the Panasonic timeline. According to the Tesla CEO, it is possible to achieve 50 percent more battery capacity with the same weight. But only in three to four years. At least Tesla is developing such a battery. Some time ago, insiders told Electrek that the secret project goes by the name of “Roadrunner” and aims to achieve mass production of a new battery cell that is said to be more energy-dense and cheaper than previous technologies.

These cells are said to have been developed by Tesla’s internal teams and include insights from the research lab in Canada led by Jeff Dahn, as well as new technologies recently acquired through the Maxwell acquisition. The Dry Electrode Technology of Maxwell would enable Tesla to produce cheaper cells with higher energy density. Again and again, Tesla patents are publicly shining with improvements in cell chemistry or building. There is always more energy density, longer usability and cheaper production in focus.

In one of his last tweets, Elon Musk has brought itself to numbers in the game and to understand that one of 400 watt hours per kilogram is no longer far away. Probably in three to four years there will be such cells. Mind you with many loading cycles and among large production conditions, not in the form of laboratory tests. To classify: According to a report of the news agency Reuters, the currently used by Tesla Panasonic cells for Model 3 and Model Y are around 260 watt hours per kilogram.

  1. We’ll see what Musk comes up with. You can also be quite controversial about how and what he does.

    But one thing is fact. It is obvious that he is currently the hunted. It seems that Musk is setting the pace with Tesla when it comes to e-mobility. Tesla may not be really profitable itself at the moment, but the ideas that come from him move an entire industry. You can see at VW how difficult it is for a dinosaur to even come close to keeping up with Tesla when it comes to software.

    And if you then think about which weddings Musk is still dancing at, then even the biggest critics have to pay a little respect to what Musk is doing. A really exciting time..
  2. In any case, the race for the battery crown will remain exciting
    After all, so is the Tesla teaser for Battery Day!
    – let’s see what the hydrogen fraction will say about it.

  3. If E.M. says that it is ‘possible’ to have batteries with 50% more capacity in 3 to 4 years, then there are two statements:
    1. Compared to its previous battery promises, this falls under the term ‘violent backtracking’.
    2. Taking into account your other faithfulness to your word, you will have 20-30% more in 5-7 years. perhaps.
    But that’s not a problem for anyone; who will still (want) to know in 4 years what he said 4 years ago.
    For me, the main content of the message is this: “Sorry folks, unfortunately there are no major improvements that quickly”. But we won’t let that spoil our fun.

  4. If at some point you get to the point that a range of 800 or 1000 KM is standard for BEVs, then that’s also a factor
    the half hour loading time no longer matters.If you only have to do this once every 1-2 months in normal operation
    or can do other travel destinations with one load.

  5. Again and again the same discussion which is not relevant ! How often are such routes driven in one go? ? 95% drive less than 100km a day ! It would be more important to be able to charge anywhere ! Every gas station should have a charger . Every employer e parking spaces ….Public parking lots, parking garages, etc. !
