Presently, the average warranty offered by carmakers is eight years or 100,000 miles, whichever comes first. That doesn’t mean the batteries go bust right after that, and owners should expect them to last for at least another 200,000 miles, albeit with diminished capacity.
But what if the world were to invent a battery good for 1 million miles?
A team of scientists from the Dalhousie University in Canada has recently published a paper detailing how such a lifespan could be achieved.
The team says it took them three years to come up with these results. The changes they propose in the current design have to do with using different electrolytes, tampering with the structure of its components, and more (if you want to get technical, you can check out the paper at this link).
“We conclude that cells of this type should be able to power an electric vehicle for over 1.6 million kilometers (1 million miles) and last at least two decades in grid energy storage,” the researchers say.
According to Wired, the team is currently in an exclusive agreement for battery development with Tesla, which could mean the American carmaker could be the first to offer the improved battery. And that’s in line with the promises made by Elon Musk earlier this year.
