Fig. 3: Mapping of manganese concentration.
From: Direct observation of Mn-ion dissolution from LiMn2O4 lithium battery cathode to electrolyte
a Charge–discharge profile for LMO cell with gel electrolyte. b MR images acquired at potential marked in red in (a) and (c) MRI signal intensity change with respect to time extracted from the active cell region (region enclosed in the blue frame in ((b)(A)) and near the LMO cathode (region enclosed in the red frame in ((b) (B)). d Mn2+ concentration mapped images acquired at potentials indicated.
