“…The neutron radiographs were obtained at the beamline neutron transmission radiography (NEUTRA) [ 84 ] of the Swiss Spallation Neutron Source SINQ [ 85 ] at the Paul Scherrer Institute with a configuration reported elsewhere; [ 86,87 ] during the experiments, the proton beam current was 1.34 mA. The NEUTRA beamline was operated with a constant beam aperture of 20 mm, leading to ≈1.3 × 10 7 n cm −2 s −1 thermal neutron flux of 25 meV mean energy.…”

in the range of 200-4000 mAh g À1 , and their highly negative redox potential below À2.5 V versus standard hydrogen electrode (SHE) can lead to a high cell operating voltage. These characteristics can enable high specific energies, which are generally given in the unit Wh kg À1 for expressing the energy-storage performance per mass of active materials or the system's total mass. However, the development of rechargeable batteries with alkali and alkaline earth metals has been extremely challenging due to the formation of dendrites, causing safety, stability, and efficiency issues. [1,4,5] As a solution to dendrite formation, solid-state electrolytes can be used as an alternative to conventional electrolytes dissolved in aqueous or organic solvents. However, according to recent studies, [5][6][7][8] dendrites can still penetrate the solid-state electrolytes, and the solid-solid interface of such energy-storage systems may cause other issues such as limited electrochemical stability window and physical contact loss between the electrolyte and the metal.Another effective approach for handling the dendrite formation is to employ liquid metal anodes. [9][10][11][12][13][14] At temperatures above 25 °C, the redox reactions of alkali and alkaline earth metals can be utilized in a molten state either in its pure metal form [13,15] or
