abstract = {The binary metal phosphides (M-P, 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 was utilized to investigate and
compare the morphological changes of copper phosphide and
tin phosphide during the initial cycle. By coupling with SEM
investigation, the surface activities of the electrodes at
different electrochemical state, including the SEI
formation, swelling and recovering, cracks appearance and
stripping at nanoscale of the material particles are
evaluated. With in-situ XRD measurement, the energy storage
mechanism was further explained. This work demonstrates
useful techniques to analyze the detailed fatigue mechanisms
of the active material, and provides new insights of the
nanostructural changes of anode materials reacting with
lithium via conversion and alloying.},
