Chemical vapor deposition-assisted fabrication of a graphene-wrapped MnO/carbon nanofibers membrane as a high-rate and long-life anode for lithium ion batteries

Abstract

Novel MnO/CNFs@G membrane by electrospinning and APCVD; this anode with high specific capacity and longest cycling life is of great interest to high energy thin film or flexible Li-ion battery.

“…Growth factors have been attempted to be incorporated into nanofibers previously, despite the fact that coaxial electrospinning studies have primarily concentrated on proteins. [78].…”

Highly Aligned Graphene Oxide for Lithium Storage in Lithium‐Ion Battery Through A Novel Microfluidic Process: The Pulse Freezing

“…The high diffusion rate observed for Anode II can be attributed to the large gap between graphite flakes, which lead to a fast but low volume of lithium intercalation due to low availability of insertion sites for lithium ions. [15,36] CV characterizations of Anode IV and Anode I give a better understanding of the lithiation/delithiation process (Figure 4c,d). When comparing the stability of different cells, the three scans of Anode I overlap greatly while those of the Anode IV show a deviation between different scans.…”

“…For instance, composites assembled using 1D carbon nanofibers were prepared via electrospinning and reached specific capacities of greater than 750 mAh g −1 at 0.1 A g −1 and 700 mAh g −1 at 1 A g −1 with decorations of Si [11] and MoS 2 , [12] respectively. In another case, 3D composites assembled using graphene and carbon nanotubes (CNTs) were prepared and reached a specific capacity of ≈1000 mAh g −1 at low current densities of 0.1 and 0.2 A g −1 , [13][14][15][16][17][18][19][20][21][22][23] and 150 mAh g −1 at a high current density of 3 A g −1 . [24] Physical assemblies such as vacuum alignment of 1D and 2D carbon materials with the presence of metal oxide decorations can also achieve a high capacity of ≈900 mAh g −1 at 0.1 A g −1 current density [25][26][27] without consuming as much energy as CVD.…”
