MIT Designs Fast Charging Lithium Ion Batteries: Could Change Electronics W
2009-03-17 22:40:00 One of the most pressing issues many people have with all electric vehicles is the long charge time needed to reach maximum range. Some can take as long as 8 hours to go from completely depleted to a 100% charge, which a large portion of consumers find too long. Now, engineers from the Massachusetts Institute of Technology may have found a solution to this long-standing problem and, in doing so, launched a new era for battery technology.
