| 英文摘要 | a high-performance anode material, nico2o4/3dhpc composite, for lithium-ion batteries was developed through direct nanoparticles nucleation on a three-dimensional hierarchical porous carbon (3dhpc) matrix and cation substitution of spinel co3o4 nanoparticles. it was synthesized via a supercritical carbon dioxide (scco(2)) expanded ethanol solution-assisted deposition method combined with a subsequent heat-treatment process. the nico2o4 nanoparticles were uniformly embedded into the porous carbon matrix and efficiently avoided free-growth in solution or aggregation in the pores even at a high content of 55.0 wt %. in particular, the 3dhpc was directly used without pretreatment or surfactant assistance. as an anode material for lithium-ion batteries, the nico2o4/3dhpc composite showed high reversible capacity and improved rate capability that outperformed those composites formed with single metal oxides (nio/3dhpc, co3o4/3dhpc), their physical mixture, and the composite prepared in pure ethanol (nico2o4/3dhpc-e). the superior performance is mainly contributed to the unique advantages of the scco(2)-expanded ethanol medium, and the combination of high utilization efficiency and improved electrical conductivity of nico2o4 as well as the electronic and ionic transport advantages of 3dhpc. |
