Today: Live Chat With GM About The Future of Batteries

PopSci talks to General Motors' director of Global Battery Systems

To succeed, electric cars require batteries that store the greatest possible amount of energy in the smallest, lightest, safest, and cheapest package possible. But batteries pose a brutal technical challenge--one subject to all manner of misunderstandings and misinformation. Can today's lithium-ion batteries cut it? What new battery technologies lie on the horizon?

Today from 2:30 to 3:30 pm Eastern time, GM's director of Global Battery Systems, Bill Wallace, and PopSci's Seth Fletcher, author of Bottled Lightning: Superbatteries, Electric Cars, and the New Lithium Economy, will field these questions in an online chat, right here.
