We've been reading and sharing reports about Tesla's potential million-mile battery for some time now. This doesn't come as too much of a surprise since many EV batteries have already been proven to last a very long time. Moreover, Tesla CEO Elon Musk shared that the battery pack in the current Model 3 should already last some 300,000 to 500,000 miles.
Now, a new patent entitled 'Dioxazolones and nitrile sulfites as electrolyte additives for lithium-ion batteries' references adjustments to battery cell chemistry for the company's cars and energy storage products. The new chemistry aims to increase battery performance and longevity while reducing costs.
