Elon Musk’s million-mile battery dreams are about to come true

Researchers have developed a new battery for electric vehicles that can last 1 million miles.

Researchers have been working on increasing the power and life cycle of the batteries we use in electric vehicles while maintaining safety standards for years. A battery reaching its end of life, with diminishing returns, would be a long term nightmare for both customers and companies.

A team in Penn State’s Battery and Energy Storage Technology (BEST) Center claims to have developed a powerful battery that can last for 1 million miles. Elon Musk promised last year that Tesla cars would at some point have batteries that last a million miles, and it seems this battery can do just that.

As Tesla learned years ago, a lithium-ion battery that has a high energy density can catch fire or even explode in certain circumstances. That’s obviously something any electric vehicle manufacturer wants to avoid, but we also want our electric vehicles to have batteries that are powerful and long-lasting. Researchers at Penn State appeared to have created a battery that’s stable, powerful and has a very long life using a counterintuitive approach.
