Ultrasmall metal oxide nanoparticles anchored on three-dimensional hierarchical porous gaphene-like networks as anode for high-performance lithium ion batteries

The well-dispersed and high-level ultrasmall metal oxides (MOx) anchored on 3D hierarchical porous graphene-like (HPG) has been fabricated via a simple hydrothermal process for the first time and the MOx-3D HPG show large reversible capacities of 986 mA h g−1 after 100 cycles at 0.1 A g−1 and long-stability.269
