“…In the commercial LIBs, graphite is usually utilized as an anode material, which is attributed to its easy Li + insertion/de-insertion, long cycling life, increasing supply of raw materials and low cost 5 6 7 8 9 . However, the relatively low lithium storage capacity of graphite is limited to be 372 mAh g −1 , assuming a reaction of Li with C to LiC 6 10 11 . Also, the rate capability induced by its low Li diffusion coefficient is limited.…”

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.

[45] Among the potential carbon-based anode materials, N-doped carbonaceous materials have attracted tremendous interest, because the nitrogen atom enhances both the surface polarity and the electric conductivity, thereby improving the Li + storage capability. [46] Right-handed twisted carbonaceous nanoribbons derived from helical m-phenylenediamineformaldehyde resin nanotubes possessed a high nitrogen content of 12.4 wt%.…”

Carbon-based nanomaterials have been widely studied in the past decade. Three approaches have been developed for the preparation of single-handed helical carbonaceous nanotubes. The first approach uses the carbonization of organopolymeric nanotubes, where the organic polymers are polypyrrole, 3-aminophenol-formaldehyde resin, and m-diaminobenzeneformaldehyde resin. The second approach uses the carbonization of aromatic ring-bridged polybissilsesquioxane followed by the removal of silica. Micropores exist within the walls of the carbonaceous nanotubes. The third approach uses the carbonization of organic compounds within silica nanotubes. This hard-templating approach drives the formation of helical carbonaceous nanotubes containing twisted carbonaceous nanoribbons. All of these helical carbonaceous nanotubes exhibit optical activity, which is believed to originate from the chiral p-p stacking of aromatic rings. They can be used as chirality inducers, and for lithium-ion storage.

“…There are solid electrodes in which material is inserted (intercalated). Graphite, for instance, allows for Li to be inserted into it while losing only a small amount (∼100 meV) of its chemical potential 11,41 . Thus lithiated graphite can serve as the anode in a lithium battery.…”

We review solid state electrochemistry, material properties, and electrochemical cells. Topics discussed are point defects, solid electrolytes, mixed ionic electronic conductors, examples of solid electrochemical cells, and electrochemical reactions. Experimental methods for characterizing the electrical properties of materials and cells are discussed, as well as typical application of solid state electrochemical systems. A brief comparison with liquid ionic conductors and electrochemical cells is presented.
