Facile Synthesis of Non-Graphitizable Polypyrrole-Derived Carbon/Carbon Nanotubes for Lithium-ion Batteries

Abstract

Graphite is usually used as an anode material in the commercial lithium ion batteries (LIBs). The relatively low lithium storage capacity of 372 mAh g–1 and the confined rate capability however limit its large-scale applications in electrical vehicles and hybrid electrical vehicles. As results, exploring novel carbon-based anode materials with improved reversible capacity for high-energy-density LIBs is urgent task. Herein we present TNGC/MWCNTs by synthesizing tubular polypyrrole (T-PPy) via a self-assembly process, then carbonizing T-PPy at 900 °C under an argon atmosphere (TNGC for short) and finally mixing TNGC with multi-walled carbon nanotubes (MWCNTs). As for TNGC/MWCNTs, the discharge capacity of 561 mAh g−1 is maintained after 100 cycles at a current density of 100 mA g−1. Electrochemical results demonstrate that TNGC/MWCNTs can be considered as promising anode materials for high-energy-density LIBs.

Polypyrrole Modified Graphite Electrode for Supercapacitor Application: The Effect of Cycling Electrolytes

“…The chemically obtained polypyrrole depends on the conditions and the chemistry of the reaction mixture formed [16]. Various additives (such as carbon nanotubes) can be added to the electrolyte to form a polypyrrole-based composite [17]. The most practical method for obtaining polypyrrole is the electrochemical oxidation because its application is easy and the polypyrrole base properties (film morphology, thickness and electrical properties) can be tailored by the deposition conditions (by changing the electrolyte conditions and the applied potential) [18].…”

Alginic acid-derived mesoporous carbonaceous materials (Starbon®) as negative electrodes for lithium ion batteries: Importance of porosity and electronic conductivity

“…As alternative materials to graphite, a variety of nano-structured carbonaceous materials have been proposed, such as carbon nanotubes, [9,10] graphene, [11,12] hollow carbon spheres, [13,14] porous carbons [15][16][17][18] or hybrids between all these systems [19,20]. Doping by heteroatoms such as nitrogen [21,22] or boron [23] has also been investigated.…”

High Lithium Insertion Voltage Single‐Crystal H2Ti12O25 Nanorods as a High‐Capacity and High‐Rate Lithium‐Ion Battery Anode Material

“…However, before LIBs can be applied on a large scale in the abovementioned fields, their cycle life, rate capability, and safety performance must be further improved . So far, graphite‐based materials are still the most commonly used anode materials in commercial LIBs, because of their high reversibility, high capacity of 372 mAh g −1 , and low cost . Unfortunately, graphite‐based materials have low potential, close to that of lithium metal, which leads to the formation of a solid–electrolyte interphase (SEI) film and lithium dendrites during the charging process.…”
