MIT researchers accidentally quadruple lithium-ion battery lifespan

There was no word if this process can be easily applied to mass-scale manufacturing but it’s perfectly conceivable that much-improved lithium-ion batteries with at least four times longer lifespan could soon make their way into our iPhones, iPads and MacBooks.

How about in Tesla and Prius? Just doubling range could be a game changer.

Anybody else see the irony of using sulfuric acid to create a longer life lithium-ion battery?

Lifespan might be about cycles, not capacity and range.

Initially I thought that, but then read "These batteries last considerably longer in terms of usable lifespan and, according to MIT, can hold up to three-times the energy."
