The MnCo2O4 anode was prepared through a simple solvothermal process followed by a post-annealing treatment. The synthesized MnCo2O4 exhibited characteristic morphology consisting of spherical microspheres constructed from nanoflake units. The olivine-type LiCoPO4 cathode was synthesized by a rapid single-step microwave-assisted solvothermal approach using a 1:1 (v/v) ethylene glycol/water binary solvent mixture and sucrose as the reducing agent. After structural characterization of the electrodes by X-ray diffraction, their electrochemical response characteristics related to the lithium insertion/extraction in half-cells and those of the MnCo2O4//electrolyte (1 M LiPF6 in EC/DMC (3:7))//LiCoPO4 full-cell were analyzed. The highest reversible capacity of MnCo2O4 and LiCoPO4 electrodes was 1167 and 107 mAh g(-1), respectively, at 0.1 C-rate. The combination of these two electrodes produced a battery with an operating voltage of 4.2 V and a reversible capacity of 95 mAh g at 0.1C, leading to an energy density of 415 Wh kg(-1) based on the cathode mass. These results indicate that the MnCo2O4 is a promising anode for high-performance lithium-ion batteries.
