Window Into A Working Lithium-Ion Battery

Using a neutron beam, researchers at The Ohio State University have able to track the flow of lithium atoms into and out of an electrode in real time as a battery charged and discharged, providing a kind of window into the inner workings of a lithium-ion battery for the first time. They believe that neutron depth profiling (NDP) could one day help explain why rechargeable batteries lose capacity over time, or sometimes even catch fire. read more
