Micro/nano-structure Co3O4 as high capacity anode materials for lithium-ion batteries and the effect of the void volume on electrochemical performance

Construction of Co3O4 nanotubes as high-performance anode material for lithium ion batteries

“…6b shows the first two galvanostatic charge/discharge curves for both electrodes between 0.01 and 3.0 V at 0.25 C. The first discharge curves of both electrodes are almost the same, indicating that the different morphologies do not change the electrochemical nature of Co 3 O 4 . During the first discharge process, the voltage curve includes a long plateau at about 0.75 V and a continuous voltage slop down to 0.01 V, which are typical characteristics of voltage trends for the Co 3 O 4 [26,27]. The voltage plateau corresponds to the reversible Lidriven decomposition of Co 3 O 4 as well as the irreversible formation of a SEI layer [23].…”

Morphology-controlled fabrication of Co3O4 nanostructures and their comparative catalytic activity for oxygen evolution reaction

“…Thus, it has attracted much attention to fabricate Co 3 O 4 with various morphology and structures, for expecting the higher activity in electrochemical applications. Recently, Co 3 O 4 nanocubes [8], nanorods [9], nanobelts [10] and nanospheres [11] have been synthesized by sol-gel [12], chemical vapor deposition [13], template method [14] and hydro/ solvothermal [15]. However, these reported preparation methods for Co 3 O 4 nanostructures have some shortcomings, such as toxicity of solvents, expensive catalysts and time-consuming process.…”

Mesoporous MnCo2O4 with a Flake‐Like Structure as Advanced Electrode Materials for Lithium‐Ion Batteries and Supercapacitors

“…Over the last decade, nanostructured transition metal oxides have been studied widely as alternative anode materials for LIBs owing to their high theoretical specific capacities (500 to 1000 mA h g À1 ) compared with the commercially used graphite (372 mA h g À1 ). [9][10][11][12][13][14][15][16] Transition metal oxides have also been investigated as electrode materials for supercapacitors. [17-20, 41, 42] However, most transition metal oxides show poor cycling performances owing to their low conductivity and typical agglomeration during long-term charge/discharge cycling.…”
