Bottom-up preparation of MgH2 nanoparticles with enhanced cycle life stability during electrochemical conversion in Li-ion batteries. Oumellal, Y., Zlotea, C., Bastide, S., Cachet-Vivier, C., Léonel, E., Sengmany, S., Leroy, E., Aymard, L., Bonnet, J., & Latroche, M. Nanoscale, 6(23):14459–14466, November, 2014. 00000 tex.ids= Oumellal2015129Paper doi abstract bibtex A promising anode material for Li-ion batteries based on MgH2 with around 5 nm average particles size was synthesized by a bottom-up method. A series of several composites containing MgH2 nanoparticles well dispersed into a porous carbon host has been prepared with different metal content up to 70 wt%. A narrow particle size distribution (1–10 nm) of the MgH2 nanospecies with around 5.5 nm average size can be controlled up to 50 wt% Mg. After a ball milling treatment under Ar, the composite containing 50 wt% Mg shows an impressive cycle life stability with a good electrochemical capacity of around 500 mA h g−1. Moreover, the nanoparticles’ size distribution is stable during cycling.
