Light and compact lithium-ion batteries sound great for electric vehicles–aside from their historical tendency to catch fire. But recent advances in electrode chemistry have made them much safer. One of the first vehicles to use the new batteries comes from a Norwegian company, Think. By year’s end, Think plans to start selling ultracompact electric cars with a range of more than 100 miles. A123 Systems of Watertown, MA, and Indianapolis’s EnerDel will provide the batteries.
