Watching lithium extraction in real time with neutrons. (IMAGE)
Caption
Operando neutron powder diffraction followed how the NMC622 positive electrode changed during the first charge-discharge cycle of the all-solid-state battery. The figure shows the evolution of the H1 and H2 phases, lattice parameters, lithium occupancy and voltage profile during cycling at C/60 and room temperature. The yellow-shaded region highlights an unusual change in phase fractions, revealing non-uniform behaviour inside the thick positive electrode composite. Ex situ neutron diffraction data collected at selected states of charge are shown for comparison (half-filled colored circles).
