Tesla boss Musk: Batteries for electric aircraft will be ready in 3 to 4 years

Many years ago, Telsa boss Elon Musk said that he had the draft for a whiz kid in the drawer. However, this can only be realized if there is progress in the energy density of the batteries. Specifically, he named the 400 watt hours per kilogram that had to be achieved. To put it into perspective: Tesla vehicles are currently on the road with batteries that have a value of 260 watt hours per kilogram. In a tweet, Musk was now optimistic that the required increase can be achieved in a timely manner. Specifically, he wrote: “400 Wh / kg with a long service life, produced in large quantities (not only in the laboratory) is not far away. Probably three to four years. ”As is often the case with the manager's announcements, it is difficult to assess to what extent the times are realistic.

Musk refers to current research

But the optimism does not seem to be entirely out of thin air either. Because only recently, the Tesla battery research team led by Jeff Dahn published a new research paper. Among other things, it deals with the improvements achieved in energy density. Among other things, these should make it possible to increase the range of electric cars by up to 280 kilometers. At the same time, however, the researchers also speak of the fact that “electrified urban air traffic” could be made possible. It is reasonable to assume that Musk was referring to this research in his tweet. The question now is how close Tesla is to series production of batteries with 400 Wh / kg. Observers assume that Tesla has already reached this target in the laboratory. The task now is to turn it into a marketable product.

It will soon be Battery Day again at Tesla

The two things that Musk also addressed in his tweet are likely to matter most: a long service life and a high production volume. Here, the company boss seems to assume that his research department will need another three to four years to achieve these goals. More information could be available on September 22nd. Then Tesla will present the latest innovations in this area at what is known as “Battery Day”. What exactly it will be about has not yet been communicated. However, some things have already been leaked. According to reports, a “one million mile battery” will be presented. This should last at least 16 years and have a total range of around two million kilometers. Here, the research work should have progressed far enough to begin series production promptly.
