Batteries warm up

摘要

For materials scientist Lynn Trahey, the impetus for a change in career direction was a single sentence she heard in 2005. Then a doctoral student in chemistry at the University of California, Berkeley, she was attending a talk about the potential of powering the world with solar energy. The speaker made an offhand comment - that energy storage is part of the equation for the future of green energy - and Trahey,s interest was piqued. "I took that and ran with it - he's right. We will need to store energy from all kinds of sources. Batteries have to be part of the innovation" she says.
