New Batteries Fix Themselves

A newly created lithium-ion battery that can heal itself may improve the life span and safety of today’s energy-storage technologies, researchers report. Rechargeable lithium-ion batteries power cell phones, laptops and other portable electronics. But, like any batteries, they tend to break down over time. "Lithium-ion batteries will continue to be the technology used for the next 10 to 15 years in electric cars," said Kristin Persson of Lawrence Berkeley National Laboratory in California, who is looking for new battery materials that not only have better energy storage but also avoid some of the pitfalls of traditional batteries. "It will take at least that amount of time to develop new materials." More>
