Electric cars and energy-efficient power grids need better batteries–and the Swedish-born serial entrepreneur and PhD has spent her career inventing them. She has founded two battery startups: Boston-Power, which makes lithium-ion batteries; and, in 2012, Cadenza Innovation, which is focused on creating better and more energy-efficient packaging for battery power cells. Her new company has raised over $10 million from angel investors, and lined up $6 million in grants from the U.S. Department of Energy and three states. This year, New York’s state government agreed to use Cadenza technology to test a clean-energy project: “The energy problem is a global problem–but we’re not approaching it as a global problem,” says Lampe-Onnerud. “It becomes a local opportunity.” –M.A.
