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

Synthesis of nanoparticles-assembled Co 3 O 4 microspheres as anodes for Li-ion batteries by spray pyrolysis of CoCl 2 solution

“…To the best of our knowledge, its electrochemical performance is much better than those reported in previous literatures [1,11,13,16,41].…”

“…Many approaches have been proposed to achieve the improvement in the electrochemical performance of TMOs materials, such as fabrication of diverse nanostructures (such as nanowires [7][8][9], nanotubes [10,11], yolk-shell [12][13][14][15], microdisks [1]), designing TMO-based hybrid/composite materials (for example, amorphous carbon [12], carbon nanotubes [16] and grapheme nanosheets [17]), and modification by coating or doping [18], with the ultimate aim of improving the electrical conductivity, enhancing naked electroactive sites, buffering the volume changes, and preventing interparticle agglomeration [19].…”

Facile preparation and performance of hierarchical self-assembly MnCo2O4 nanoflakes as anode active material for lithium ion batteries

“…Recently, much attention has been given to transition metal oxide anodes because they have very high theoretical capacities (500 to 1000 mAh g À1 ) [3]. Besides, various active materials with different structure and morphology for LIBs have also reported, for example, ZnO flower-like [4], NiO nanosheets [5], Co 3 O 4 nantubes [6], hollow structures [7][8], nanospheres [9][10], and so on. Among those transition metal oxides reported [11][12][13][14], Co 3 O 4 has been regarded as a promising anode material for LIBs due to its excellent electrochemical activity and high theoretical capacity of about 890 mAh g À1 .…”

Construction of carbon nanoflakes shell on CuO nanowires core as enhanced core/shell arrays anode of lithium ion batteries

“…Over the past decades, much attention has been paid to investigate transition metal oxides as anode materials for LIBs because of their higher theoretical capacity compared to the commercial graphite anodes [1][2][3][4][5][6][7][8]. Among the explored transition metal oxides, CuO is considered as one of the most promising candidates due to its high theoretical capacity (674 mAh g -1 ), low cost, chemical stability and environmental friendliness [1,9,10].…”
