Mobile devices have come a long way in a short period of time. It seems as if smartphones and tablets are capable of just about anything, however battery restrictions are holding these powerful devices back. The rate of innovation has not be been the same in the battery field and users are forced to bring chargers with them wherever they go. Researchers at the University of Illinois at Urbana-Champaign are looking to change that with a new lithium-ion battery that is 2,000 times more powerful than comparable technologies. “This is a whole new way to think about batteries,” Lead researcher William P. King said. “A battery can deliver far more power than anybody ever thought. In recent decades, electronics have gotten small. The thinking parts of computers have gotten small. And the battery has lagged far behind.”
