Researchers at Rice University ,Houston,in the United States,have found that batteries made using asphalt attain full charge in a few  minutes.  Asphalt is a semi – solid form of petroleum.”  The capacity of these batteries is enormous but what is equally remarkable is that we can bring them from Zero charge to full charge in five minutes,rather than the typical two hours or more needed with other batteries “ said James Tour,one of the researchers .  The team of scientists also found that such batteries didn’t develop deposits.  These mossy deposits invade a battery’s electrolyte .  If they extend far enough ,they short – circuit the anode and cathode and can cause the battery to fail,catch fire or explode.  But the asphalt-derived carbon prevents any dendritre formation,” the university said on its website.
