Electrophoretic deposition of nanographitic flakes/Co3O4 nanocomposite layers synthesized by solvothermal process for improved lithium-ion-battery anode

Template-free synthesis of Co3O4 microtubes for enhanced oxygen evolution reaction

“…Recently, Co-based oxide materials have attracted increasing attention owing to their facile preparation, relatively low cost, and high electrochemical activity for the electrocatalytic OER [6,7]. To analyze the intrinsic OER electrocatalytic performance of Co3O4-based materials in depth, several strategies have been developed, including doping with transition metals, designing unique microstructures, and improving catalyst conductivity using ideal conductive materials [8].…”

Unique Double Carbon Protection Structured Co<sub>3</sub>O<sub>4</sub> Anode for Lithium Ion Battery

“…Some reported Co 3 O 4 -based nanostructures in the last two years are listed in Table 1. By contrast, the cycling performance of Carbon aerogel (CA)/Co 3 O 4 /Carbon (C) is higher than those of Co 3 O 4 nanocage/Co 3 O 4 nanoframework/TiO 2 [12], Co 3 O 4 nanocubes [13], Hollow Co-Co 3 O 4 /CNTs [14], Co 3 O 4 /nitrogen-doped carbon composite [15] and Co 3 O 4 nanocomposite [19]. But, it is admirable that Co 3 O 4 /nitrogen-doped carbon composite in reference [16], Co/Co 3 O 4 nanoparticles in reference [17] and porous Mn-Co 3 O 4 /C microspheresin reference [18] show super cyclability and rate capability.…”

“…For commercialized lithium battery, the anode material of graphite has a relatively low theoretical specific capacity of 372 mAh/g, which cannot meet the increasing demands of energy density for lithium batteries. Recently, a lot of research has been devoted to the electrochemical active transition metal oxides (TMOs) as promising anode materials (SnO 2 [4], TiO 2 [5], ZnO [6], Fe 3 O 4 [7] and α-Fe 2 O 3 [8], Co 3 O 4 [9]- [19]), due to their high theoretical capacities (>700 mAh/g) and abundance in nature. Among these TMOs, Co 3 O 4 is one of the most promising candidates, which owns a large theoretical capacity (about 890 mAh/g) and remarkable electrochemical properties [9]- [19].…”

Binder-Free LiNi0.8Mn0.1Co0.1O2/Multi-Walled Carbon Nanotube Prepared by One-Step Electrophoretic Deposition Method for Efficient Li-Ion-Battery Cathodes

“…[25][26][27][28] In our previous works, we have synthesized and prepared different intercalation-type cathode materials and anode materials with conventional drop-casting and doctor-blade methods. [29][30][31][32] Our group recently used a novel EPD method to prepare binder-free anode material of NGr-Co 3 O 4 with the progressed results in the anode of the Li-ion performance 27,33 and therefore we also decided to employ this EPD method to create binder-free NMC8111 cathode material. In this work, we have first prepared the cathode electrode consisting of NMC811 as the active material, PVDF as the binder material, and carbon black as a conductive agent by the doctor-blade method.…”
