Supercritical CO2 (scCO2) is often used to prepare graphene/metal oxide nanocomposite anodes for high performance lithium-ion batteries (LIBs) by the assisted solvothermal method due to its low viscosity, high diffusion, zero surface tension and good surface wettability. However, the formation mechanism of metal oxides and the combination mechanism between metal oxides and graphene in this system are superficial. In this work, a cobalt monoxide/graphene (CoO/G) nanocomposite is fabricated via the scCO2 assisted solvothermal method followed by thermal treatment. We elucidate the mechanism that amorphous intermediates obtain by the scCO2 assisted solvothermal method, and then ultrafine CoO nanoparticles are crystallized during the heat treatment. In addition, scCO2 can promote CoO to be tightly fixed on the surface of graphene nanosheets by interfacial chemical bonds, which can effectively improve its cycle stability and rate performance. As expected, the CoO/G composites exhibit higher specific capacity (961 mAh g−1 at 100 mA g−1), excellent cyclic stability and rate capability (617 mAh g−1 after 500 cycles at 1000 mA g−1) when applied as an anode of LIB.

Co3O4 nanocrystals have been synthesized via an ordinary one-step calcination of a cobalt-based 2D coordination polymer [Co(tfbdc)(4,4[Formula: see text]-bpy)(H2O)2]. As an anode material for lithium-ion batteries, the obtained Co3O4 nanocrystals exhibit high reversible capacity, excellent cyclic stability and better rate capability. The reversible capacity of the Co3O4 nanocrystals maintains 713[Formula: see text]mA[Formula: see text]h[Formula: see text]g[Formula: see text] after 50 cycles at a current density of 50[Formula: see text]mA[Formula: see text]g[Formula: see text]. Our results confirm that searching for metal oxides nanomaterials used as anode materials of lithium ion batteries via the calcinations of 2D coordination polymer is a new route.
