“…This signifies that PPy synthesized by our self‐degrading template method has been successfully obtained and that there are no other chemical reactions between sulfur and PPy in the process of ball milling. The formation mechanism of nanotubular PPy is the same as that reported previously . FeCl 3 was mixed with methyl orange (MO) to form a fibrillar complex template.…”

To explore the potential application of lithium–sulfur batteries (LSBs) in the emerging electric vehicle market, sulfur–polypyrrole (S‐PPy) is prepared by a facile ball‐milling route, in which polypyrrole is synthesized by using ferric chloride as an oxidant in a self‐degrading template method. Compared with sulfur, S‐PPy possesses a higher discharge capacity, much better cycling stability, and better rate performance. At a current density of 200 mA g−1, the discharge capacity of S‐PPy is maintained at 675 mA h g−1 after 150 cycles, and even at a current density of 1675 mA g−1, the retained discharge capacity is still 617 mA h g−1 after 100 cycles. The retained discharge capacity of pure sulfur, however, is only 150 mA h g−1 after 150 cycles at a current density of 200 mA g−1. These results indicate that S‐PPy, with its facile, low‐cost, and eco‐friendly synthesis, could be a potential cathode material for LSBs.

“…However, there are still some shortcomings in the traditional graphite anode materials, which seriously limit its application (Groult et al, 2005;Wu et al, 2013;Hashimoto et al, 2019;Kim et al, 2019). First of all, the theoretical capacity of graphite negative electrode is only 372 mAh·g −1 , which is far from meeting the requirements of high performance lithium-ion batteries; secondly, the stability of layered structure is poor, which is easy to collapse after a long charge-discharge cycle, resulting in a serious decrease in specific capacity and a large reduction in energy storage life; thirdly, electrolyte decomposition will result in large irreversible capacity during the first charge-discharge process.…”

In order to develop new type of carbon anode material with high performance, a novel organic carbon material polyacrylonitrile (PAN) hard carbon was prepared by calcination of polypropylene cyanide at 1,050 • C. The obtained PAN hard carbon is used as the negative electrode material of lithium ion battery, showing an initial capacity of 343.5 mAh g −1 which is equal to that of graphite electrode (348.6 mAh g −1 ), and a higher initial coulomb efficiency of 87.9% than that of graphite electrode (84.4%). Moreover, the PAN hard carbon electrode shows superior cycle stability and rate performance at different current rates. The charge capacities are 320.1, 219.0, 212.9, and 123.5 mAh g −1 at current rates of 0.2, 1, 2, and 3 C, with coulombic efficiencies of 98.1, 100.6, 88.1, and 110.0%, respectively, which are higher than those of graphite electrode (83.8, 97.6, 98.8, and 94.1%). In addition, the charging capacity of PAN hard carbon electrode can still remain at 284.3 mAh g −1 (0.2 C after 200 cycles), 226.4 mAh g −1 (1 C after 300 cycles), 149.5 mAh g −1 (2 C after 400 cycles), and 120.0 mAh g −1 (3 C after 100 cycles), with capacity retention rates of 78.2, 111.9, 79.7, and 88.6%, respectively. The capacity and capacity retention rate after cycling are significantly higher than those of graphite electrode, indicating that the PAN hard carbon electrode shows superior rate performance, which would provide a new idea for the development of novel negative electrode material with high performance.

“…Even up to 4 A g −1 , the reversible capacity of NGCNTs remains in 280.1 mAh g −1 . The improved performance of NGCNTs is attributed to the non-graphitic form, tubular morphology and cross-linked conducting networks 14 . In summary, the non-graphitizable PPy-derived carbon manifests satisfactory electrochemical performance; however, its reversible capacity, rate performance and cycling stability still need to be greatly improved for high-energy-density LIBs.…”

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.
