Significance Lithium metal is an ideal anode material for rechargeable Li-ion batteries, but its use is prevented by the growth of lithium deposits, or “dendrites,” during charging that can cause performance loss and serious safety concerns. Understanding the growth of dendrites in situ is crucial for the progress of this technology. MRI has been limited to directly studying the lithium signal until now, resulting in low sensitivity, limited resolution, and long experiment times. We present here an approach that detects the “shadows” of dendrites growing through the electrolyte, allowing the dendrites’ growth to be imaged very quickly in 3D with high resolution. This technique can also be applied to other electrodes, such as those based on sodium, zinc, and magnesium.
