Porous Co3O4 nanoplatelets by self-supported formation as electrode material for lithium-ion batteries

Fabrication of three-dimensional porous structured Co3O4 and its application in lithium-ion batteries

“…Many different approaches have been developed to improve the electrochemical performance of cobalt oxides electrode materials. One major effort has been to decrease the dimension of cobalt oxide and, thus, allow for short solid state diffusion path for Li ions and large contact area between materials and electrolyte [1,[6][7][8].…”

Enhanced rate performance of cobalt oxide/nitrogen doped graphene composite for lithium ion batteries

“…However, its large irreversible capacity loss and poor cycling stability have restricted its general application, owing to the large volume change during the charge/discharge process and, the unavoidable particle aggregation associated with the lithium ion insertion and extraction processes after long cycling. [5][6][7][8] It is well accepted that electrode with the proper nanosize distribution could reduce the path length of lithium ion transport and improve electrolyte penetration because of the large contact area between electrode and electrolyte, which greatly contributes to the electrochemical performance during cycling. [9][10][11] A strategy has been utilized to circumvent the volume change and aggregation problems by hybridizing with conducting matrices, such as amorphous carbon coatings 11 or carbon nanotubes, 12 which could interlink Co 3 O 4 particles to improve their electrochemical performance.…”

Electrochemical study of NiO nanoparticles electrode for application in rechargeable lithium-ion batteries

“…For example, forming composites with conductive materials such as carbon is a very common and useful method, but often reduces the mass specific capacity [11,12]. So, preparing materials with a special morphologies such as a porous structure [13][14][15][16], nanoarrays [6,17], microspheres [18][19][20][21][22] and some others [23] to enhance the electrochemical performance has attracted much attraction.…”
