The potential of metallic lithium to become the anode material for next-generation batteries is hampered by significant challenges, chief among which is dendrite growth during battery charging. These dendrite structures not only impair battery performance but also pose safety risks. In this study, a recently introduced indirect imaging approach which is based on 1H MRI of the electrolyte was used to sequentially image dendrite growth in different configurations of symmetric lithium cells. The measured sequential images allowed for the measurement of dendrite growth in each cell using volumetric analysis. The growth results confirmed our theoretical prediction that the growth across cells is uneven in a parallel circuit, and even in a series circuit.
