Car batteries don’t last forever. Generally, they need to be replaced every five to six years, sometimes sooner, depending how worn they are. But engineers working to develop batteries for Tesla claim to have created one that can outlast a typical vehicle’s power source by over a decade.
Researchers at Dalhousie University in Canada tested a new lithium-ion cell battery that could last for roughly 20 years, or one million miles, according to a report published last week in the Journal of The Electrochemical Society. The team received funding from Tesla and noted in the report that the batteries could be particularly useful in “robo taxis,” like the ones Elon Musk has theorized. But the batteries, which are designed for electric cars, could also amp up the current lifespan of chargeable vehicles that are already on the road.
Musk has repeatedly mentioned that he wants to let loose a fleet ...
