Morphology study using electrons and neutrons!

In order to improve battery performance one has to know what is happening inside. Yet the all important characteristics can only be found on the sub micron level, so you can’t watch it with the naked eye. In this paper we use a combination of Focused Ion Beam milling Scanning Electron Microscopy (FIB-SEM) and Neutron Depth Profiling (NDP) to reveal the sub micron morphology and how this effects your lithium concentration during cycling, moreover we demonstrate a cost effective method to improve the rate capability of these electrodes.
