What about the rest of us? Can we expect our gadgets to last longer than a day any time soon? “As long as our batteries are based on a chemical reaction, we will have huge limitations,” Buchmann says. “The health of a battery is almost like the health of a living organism or human being. We have to take care of it.” Limer says: “I don’t think things will change much in 10 years. A realistic future to hope for is one where even in extreme heavy use you can get through a day without losing your battery.” Right now, he adds, what we have is “a battery stalemate”.
