A 3D Organically Synthesized Porous Carbon Material for Lithium‐Ion Batteries

Abstract

We report the first organically synthesized sp-sp hybridized porous carbon, OSPC-1. This new carbon shows electron conductivity, high porosity, the highest uptake of lithium ions of any carbon material to-date, and the ability to inhibit dangerous lithium dendrite formation. The new carbon exhibits exceptional potential as anode material for lithium-ion batteries (LIBs) with high capacity, excellent rate capability, long cycle life, and potential for improved safety performance.

Cucurbit[6]uril‐Derived Nitrogen‐Doped Hierarchical Porous Carbon Confined in Graphene Network for Potassium‐Ion Hybrid Capacitors

“…[8,9,11] Heteroatom-doped porous carbon (HDPC) with tunable porosity, abundant electron-donating heteroatoms, excellent chemical stability, and amorphous carbon framework has been exhibiting promising application prospects in many emerging fields such as energy storage/conversion, catalysis, biomedicine, and gas capture/separation. [16][17][18] Acting as PIHCs anode, HDPC not only contributes a considerable reversible specific capacity, but also possesses superior kinetics and cyclability than other types of anode materials. [14,15] However, the kinetics of most reported HDPC anodes is still far from matching that of capacitor-type cathodes.…”

Porous Organic Polymers as Promising Electrode Materials for Energy Storage Devices

“…[86] Besides COFs, amorphous spsp 3 hybridized porous carbons have been employed as anode materials for LIBs. [87] The porous carbon is a prominent anode material for efficient and stable LIBs by virtue of high porosity, good electron conductivity, high uptake of lithium ions, and the capability to prohibit the formation of dangerous lithium dendrite.…”

Nitrogen‐Doped Porous Graphene Coated with Fe3O4 Nanoparticles for Advanced Supercapacitor Electrode Material with Improved Electrochemical Performance

“…Therefore, it is meaningful to introduce pore structures on the graphene layers, because it can provide a wealth of transport channels, thereby effectively improving the penetration and transport characteristics of materials and making the best use of the active sites inside the materials. [ 22–25 ] What is more, as nitrogen atoms can not only provide extra electrons to the graphene layer and avoid graphene from excessive stacking, but also provide more defect sites for the synthesis of Fe 3 O 4 nanoparticles, nitrogen atoms are always doped into graphene layers to form nitrogen‐doped graphene. [ 26–31 ] To the best of our knowledge, although extensive research has been carried out on G/Fe 3 O 4 , researches on incorporating pore structures and nitrogen atoms simultaneously into the graphene layers of G/Fe 3 O 4 to improve its electrochemical performance are still scarce.…”
