USA: A123 engineer making batteries better, bigger

It’s difficult to build a battery that holds a charge for long periods — especially when materials are potentially unstable. It can be even tougher when you’re developing batteries large enough to store electricity for the power grid.

But that’s the job of Greg Tremelling, 31, an electrical engineering manager who leads the big battery team at A123 Systems Inc. of Waltham.

Tremelling’s team focuses on applications for commercial transportation and large-scale energy storage, helping to create battery configurations that can power hybrid buses or allow operators to pull more energy from wind farms and solar generating plants.
