Synthesis of Co@CoO/C by micro-tube method and their electrochemical performances

“…Lithium-ion batteries (LIBs) are extensively utilized in mobile electronic devices and electric vehicles due to their unparalleled performance compared to other conventional secondary batteries [ [1] , [2] , [3] , [4] , [5] ]. Negative electrode materials, as an indispensable component of lithium-ion batteries, have been the primary focus of research.…”

“…Negative electrode materials, as an indispensable component of lithium-ion batteries, have been the primary focus of research. The conventional theoretical specific capacity of graphite anode materials is reported to be 372 mAh/g [ [5] , [6] , [7] ], no longer suffices to meet the burgeoning demand for high-capacity and high-performance batteries. High theoretical specific capacity (712 mAh/g) and abundant resources make CoO as an excellent alternative to graphite materials.…”

“…However, the synthesis process of these carbon carriers is complicated and costly, making it difficult to use them on a large scale. Currently, the primary techniques utilized for synthesizing CoO electrode materials include hydrothermal synthesis [ 21 ], ammonia-assisted synthesis [ 5 , 22 ], electrospinning [ 23 ] and other related methodologies. Although these methods can be utilized to prepare nanostructures with diverse morphologies, they all possess certain limitations such as intricate synthesis procedures, challenging operations and controls, which ultimately increase the cost of fabricating CoO electrode materials.…”

Analysis of CNT and rGO Mediation for an Efficient Super-Capacitive Response in Cr-Doped Co3O4 Based Composites

“…6 Activated carbon powders are frequently utilized as the main components in commercially available EDLC SCs due to their significant qualities, such as high specific surface area (A), outstanding thermal stability, superior conductivity, and remarkable resistance to electrolyte corrosion. 7 For practical utilizations, however, they have a low energy density, often in the range of 4-5 W.h/kg for fully made cells, which is far lower than the energy density of batteries. Many studies have been done on how to boost their energy densities, including employing electrolytes with large potential windows and carbon electrode materials with high A to increase capacitance and operational voltage, respectively.…”

Advances in Nano-Electrochemical Materials and Devices

“…The recent critical developments in nano-electrochemical materials are devices that focus on developing nanostructured electrode material [ 3 ], nano-electrochemical sensors [ 4 ], nanomaterials for energy storage and conversion [ 5 , 6 ], etc. Developing a novel material synthesis process enables smaller-scale prototypes for application, optimization, and innovation experimentation.…”
