An international team of researchers led by Stanford University have developed rechargeable batteries that can store up to six times more charge than ones that are currently commercially available, reports Tech Xplore. The advance, detailed in a new paper published Aug. 25 in the journal Nature, could accelerate the use of rechargeable batteries and puts battery researchers one step closer to creating a high-performance rechargeable battery that could enable cellphones to be charged once a week and help electric vehicles travel six times farther between recharging. The new so-called alkali metal-chlorine batteries, developed by researchers led by Stanford chemistry professor Hongjie Dai and doctoral candidate Guanzhou Zhu, relies on the back-and-forth chemical conversion of sodium chloride (Na/Cl2) or lithium chloride (Li/Cl2) to chlorine. When electrons travel from one side of a rechargeable battery to the other, recharging reverts the chemistry back to its original state to await another use.
