A Multiple Working Electrode for Electrochemical Cells: A Tool for Current Density Distribution Studies

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.
