Researchers at Drexel University 's College of Engineering in Philadelphia have developed a battery electrode design that could work as quickly as a supercapacitor , but also store much more energy , according to an article in the journal Solar Energy . "Eventually, appreciation of this fact will lead us to car, laptop and cell-phone batteries capable of charging at much higher rates—seconds or minutes rather than hours." The team developed a thin film of the highly conductive material MXene for the electrode structure . MXene is macroporous ( with many small openings ) , which allows ions to quickly reach electrical charge storage sites , allowing the storage of much more power .
