Uneven distribution : The multiple working electrode for electrochemical cells (see image) is a unique tool for the quantitative study of current density distribution in lithium‐ion batteries. During the cycling of the cell even at a low C‐rate of C/37, an inhomogeneity in the average current density distribution of more than 8 % is observed. WE=working electrode, CE=counter electrode.
