Co₃O₄/porous electrospun carbon nanofibers as anodes for high performance Li-ion batteries

Abstract

This paper reports a facile route to synthesize porous carbon nanofibers containing cobalt and cobalt oxide nanoparticles (CoOx/PCNF) as anodes for Li-ion batteries.

CuO Quantum Dots Embedded in Carbon Nanofibers as Binder‐Free Anode for Sodium Ion Batteries with Enhanced Properties

“…Although a lower temperature (600 °C) leads to an uniform 1D morphology, it will result in poor electrical conductivity due to the incomplete carbonization, just as illustrated in Figure S10 (Supporting Information). [ 18 ] Obviously, the higher temperatures (700, 750 °C) induce some agglomeration of the composite nanofi bers. Considering the uniform morphology of nanofi bers, 650 °C should be the most appropriate carbonization temperature.…”

Cobalt Oxide-Carbon Nanosheet Nanoarchitecture as an Anode for High-Performance Lithium-Ion Battery

“…11,12 In this respect, a variety of carbonaceous materials, including porous carbons, 13 carbon aerogels, 11 carbon nanofibers, 14,15 carbon nanotubes, 16,17 and graphene, 12,18,19 have been utilized for the incorporation of metal oxides. Graphene with high electrical conductivity, good flexibility, and high chemical stability has been widely used to support metal oxides, which facilitates electron transport and Li + diffusion of anchored host materials.…”

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

“…However, the performance of bulk Co 3 O 4 is still not satisfactory because of its low ion/ electron transfer and fast capacity fading, which are still stubborn problems limiting its practical application. These problems are generally caused by their intrinsic kinetic limitations and drastic volume variation during the electrochemical cycling process [10,11]. The performance of electrode materials is mainly determined by the electrochemical activity and kinetic feature of the electrode materials.…”
