Current rechargeable EV battery packs are engineered to be able to withstand plenty of abuse: thousands of discharge/recharge cycles, extreme ambient temperatures at both ends of the scale - in essence, all the things the typical consumer might expect from their gas-powered vehicle. But apart from the total driving range and typical recharge time, one of the biggest limitations facing the EV battery is longevity, with packs often effectively losing their ability to hold a charge after 100,000 to 200,000 miles.
Now, General Motors says it's getting very close to an EV battery capable of lasting a million miles, and it could thrust the automaker to the fore in the electric vehicle space.
