Compton scattering imaging using high-energy synchrotron x-rays allows the visualization of the spatio-temporal lithiation state in lithium-ion batteries probed in-operando. Here, we apply this imaging technique to the commercial 18650-type cylindric

In Li/S and Mg/S batteries, the charge and discharge of the sulfur cathode proceeds through a cascade of bivalent Sx2– and radical Sy•– polysulfide intermediates. The presence of Li+ or Mg2+ cations in the electrolyte determines the type of int
