A Comparison Study of Confinement Effect of PEDOT and CNT for Sulfur Nanocomposites in Li-S Battery Application

doi:10.33790/crmc1100105

Abstract

Highlights

Traditional lithium-ion batteries are not viable for high-powered, portable electronics due to their low specific capacity, making them impossible, by either the economics or material limits, to integrate into efforts such as electric vehicles and large-scale storage operations [1,2]
The structure 1 in Figure 1 is comprised of an sulfur¬ nanoparticles (S-NPs) solution created from the chemical reaction of sodium thiosulfate and hydrochloric acid (HCl), sonicated onto a lattice of Multi-walled carbon nanotubes (MWCNTs), which is in turn sonicated with polymerized EDOT to produce the resulting structure
The S-NPs are on the scale of between 0.5 and 3 microns in diameter and are relatively uniform in distribution. The size of these S-NP particles is owed to the introduction of PVP causing the formation of these spherical structures due to the hydrophobic nature of sulfur attracting the hydrophobic tails of the PVP

Summary

Introduction

Traditional lithium-ion batteries are not viable for high-powered, portable electronics due to their low specific capacity, making them impossible, by either the economics or material limits, to integrate into efforts such as electric vehicles and large-scale storage operations [1,2]. Upon compression of the sulfur-infiltrated CNT foam, a dense structure is produced, exhibiting active material loading of 79 wt% and gravimetric capacity of 1039 mAh/g.
