Abstract
We report on in situ and ex situ concentration measurements in lithium/poly mer-electrolyte/lithium cells during cycling. We have used three different methods which give complementary results, in good agreement with theoretica l predictions and previous concentration measurements by Raman confocal mic rospectroscopy. Our methods allow to obtain concentration maps in the elect rolyte, in particular, when dendrites are observed: from these measurements , we can correlate the onset of dendritic growth with local concentration g radients.
