  • Got battery? Lots of low battery hacks but no quick fix

    The New York Times - 01/22/2015

    The common lithium-ion battery that’s used to power laptops, cellphones and tablet computers has improved in recent years. Battery capacity has tripled since 1990, says K. M. Abraham, a professor at Northeastern University who researches batteries. But it’s not nearly enough to keep up with the demand we gadget addicts have for constant use of skinny, light mobile devices, which limits battery size.

    Two billion mobile phones were shipped worldwide in 2014, 75 percent of which were smartphones, says longtime technology analyst and president of Creative Strategies, Tim Bajarin. Demand is growing by 10 to 12 percent each year. And we want to send email, play games, stream music and videos, get step-by-step directions — all battery hogs.

    “We are reaching the limit of what a good battery material can do,” says Abraham. “Going beyond what we have now is taking a new understanding of chemistry, material science…People are working all over the world on it, but there is nothing on the horizon.”
