A facile electrospinning and electrospraying synchronization technique for preparation of high performance MnO/C@rGO composite anodes for lithium storage

Abstract

A facile electrospinning and electrospraying synchronization technique is used to assemble 1D nanowires with 2D graphene sheets to build as 3D MnO/C@rGO composite thin film. The raw material MnO2powder was recovered from spent Zn/MnO2batteries.

Electrospun Carbon/CuxO Nanocomposite material as Sustainable and High Performance Anode for Lithium‐Ion Batteries

“…Another important contribution to the stability and performance of this nanocomposite material, is provided by the Polyacrylic acid binder, which thanks to its high number of carboxylic groups in the polymer backbone, enables the formation of hydrogen bonds with both copper oxide nanoparticles,improving the adhesion with the current collector and the mechanical properties of the electrode. Moreover, as it has been already reported, the PAA binder acts as artificial SEI, which makes up for an additional stabilizing layer during electrochemical cycling.…”

“…Between them, the adoption of effective carbon supporting matrices is not always easy, and often requires the adoption of complex syntheses and techniques which hamper their scale up on an industrial perspective. To easily obtain innovative morphologies while implementing effective 3‐D support and conducting frameworks, electrospinning has gained much attention due to its relatively easy experimental setup, operational straightforwardness and scale up capabilities . In addition to that, also electrode processing of the final composite material has a determining impact on sustainability and cycling performance .…”

“…To easily obtain innovative morphologies while implementing effective 3-D support and conducting frameworks, electrospinning has gained much attention due to its relatively easy experimental setup, operational straightforwardness and scale up capabilities. [24][25][26][27][28][29] In addition to that, also electrode processing of the final composite material has a determining impact on sustainability and cycling performance. [30][31][32][33] In this work we present the easy and scalable electrospinning synthesis procedure of a Cu 2 O/PAN derived carbon nanocomposite, coupled with an improved and sustainable electrode processing procedure based on the PolyAcrylic Acid (PAA)-Ethanol binder/ solvent couple which ensured high performance on a long cycling life perspective.…”
