It was not long ago that we informed you of the prospects of Tesla battery researcher Jeff Dahn about electric car batteries, which could be an important point of change for electric vehicles. We also shared an exclusive interview with the battery guru via Sean Mitchell ToutThingsEV Youtube channel.
In this interview, Dahn explained that he could not really talk about Tesla's batteries. But, we put two and two together and thought something had to be in the works.
With the announcement of Tesla's battery production potential and the acquisition of Maxwell Technologies, the battery manufacturer and leader of supercapacitors, the automaker of Silicon Valley only needs a short time to come up with a new technology. ultramodern batteries.
The best part of this whole situation is that Tesla's batteries, in partnership with Panasonic, have already proven that they far exceeded the best of the market.
Today, Dahn, in its research partnership with the all-electric manufacturer of Silicon Valley, boasts battery cells that can last a million kilometers. These cells could potentially become commonplace in the upcoming Tesla robo-taxis.
Tesla CEO Elon Musk has been touting the company's fully autonomous technologies for years. This is supposedly very close to completion. The CEO has gone so far as to say that once technology is developed, it will cost more and more expensive and will significantly increase the resale value of equipped cars.
Dahn conducts research on batteries in his own laboratory, in partnership with Tesla and other investors. According to a recent report by ELECTrek, sources said that he was about to release a battery cell potentially capable of a million miles. The report says that it uses a "monocrystalline NMC cathode" to obtain such results.
The recent Dahn battery report explains (via ELECTrek):
We present a wide range of test results for an excellent chemistry of light-energy density lithium-ion pocket cells, which will serve as benchmarks for academics and companies developing advanced lithium-ion cell chemistries. and other cells "beyond lithium-ion" to (hopefully) exceed. These results are far superior to those used by researchers who model the mechanisms of cell failure. They are therefore more representative of modern Li-ion cells and should be adopted by modellers. Up to three years of testing have been done for some of the tests. The tests include long-term charge-discharge cycles at 20, 40 and 55 ° C, long-term storage at 20, 40 and 55 ° C and high precision coulometry at 40 ° C. Several different electrolytes are taken in this chemistry LiNi0.5Mn0.3Co0.2O2 / graphite, including those that can promote fast charging. The reasons for the degradation of cell performance and impedance growth are examined using several methods. We conclude that cells of this type should be able to power an electric vehicle for more than 1.6 million kilometers and last at least two decades in energy storage on the grid.
We are talking about battery cells that last two to three times longer than Tesla's current battery cells.
We would like to know what you think. Is this something that is plausible in the near future or is it far like a battery technology in the solid state. Tell us what you think in the comment section below.
