Using Neutrons to Peer Inside a Battery Designed for Hybrid Locomotives
Rechargeable batteries may soon provide greater energy efficiency not only for road traffic, but also for rail transport. Scientists at the research neutron source FRM II of the Technische Universitaet Muenchen (TUM) are taking a closer look at a high performance rechargeable battery for future hybrid locomotives. The focus is on a sodium/iron chloride battery manufactured by General Electric (GE). The study reveals the distribution of chemical substances within the battery during various states of charge.
