Cellphones charged in 60 seconds
Smartphones could soon be charged in less than a minute now that scientists at Stanford University, in the US, have invented an aluminium battery so powerful it could revolutionise how power is stored. An iPhone6 currently takes about two hours to fully charge its battery but with the new battery it would take only 60 seconds - and the new battery will keep going for seven times longer than the old lithium-ion type.Although the new battery currently only produces half the voltage of a typical lithium battery, the scientists believe they will improve the output within the next few years.Hongjie Dai, professor of chemistry at Stanford University, said: " I see this as a new battery in its early days. "The new aluminium battery is far "greener" and safer than its forerunners.Discarded conventional alkaline batteries pollute the environment and lithium-ion batteries can burst into flames.The research was published in the journal Nature. ..
