Tesla launches batteries that last up to a million miles

Thanks to research conducted by a group of scientists from Dalhousie University, Tesla can display within its products a lithium-ion battery that “should be able to power an electric vehicle for more than 1 million miles” while losing less than 10% of its energy capacity during its useful life, according to the researchers who are also the manufacturers of this innovation.

The information was published in an article in The Journal of the Electrochemical Society in which they assure that their battery significantly exceeds a similar one previously reported. This group of Dalhousie battery researchers currently maintains exclusive agreements with the automotive company Tesla.

The battery design is very useful, especially for autonomous taxis and long-haul electric trucks, two products that Tesla is developing. “Full details of these cells have been provided, including electrode compositions, electrode charges, electrolyte compositions, additives used”, amon others, said physicist Jeff Dahn, one of the world’s leading lithium-ion researchers.

Dahn also said that these lithium-ion batteries use lithium oxide, nickel, manganese, cobalt or NMC, for the positive electrode (cathode) of the battery and artificial graphite for its negative electrode (anode). The electrolyte, which carries lithium ions between the electrode terminals, consists of a salt mixed with other compounds.

Currently, Tesla cars can reach up to 370 miles per charge, which is well above the reach of other companies’ electric vehicles. As for the latter, the metrics translate on how far a car can drive with a single charge and how many charges it can take from the battery before it stops working. In general terms, there is a trade-off between energy density and battery life: if you want more than one, you get less from the other.
