$Voltage and capacity curves from a LMR high-energy cathode showing voltage fade phenomena after 26 cycles (red curves are charge and discharge for the 2nd cycle while blue represents the 26th cycle) and layered-to-spinel transformation mechanism deduced from neutron diffraction. Insets show that the initial layered structure transforms to the spinel structure through an intermediate state having cations in ‘tetrahedral’ sites.$
