abstract = {The binary metal phosphides (MP, M = Cu, Fe, Sn, Sb)
compounds are of great interest as negative electrode
materials for high energy density lithium-ion batteries.
However, the morphology and structural changes at the
nanoscale upon electrochemical (de)lithiation are not clear
yet, which require further detailed investigation. In situ
neutron scattering technique is utilized to investigate and
compare the morphological changes of copper phosphide and
tin phosphide during the initial cycle. By coupling with
scanning electron microscopy investigation, the surface
activities of the electrodes at different electrochemical
states, including the solid electrolyte interphase
formation, swelling and recovering, cracks appearance, and
stripping at nanoscale of the material particles are
evaluated. With in situ X-ray diffraction measurement,the
energy storage mechanism is further explained. This work
demonstrates useful techniques to analyze the detailed
fatigue mechanisms of the activematerial, and provides new
insights of the nanostructural changes of anode materials
reacting with lithium via conversion and alloying.},
