Superlithiation Performance of Pyridinium Polymerized Ionic Liquids with Fast Li⁺ Diffusion Kinetics as Anode Materials for Lithium‐Ion Battery (Small 39/2023)

Superlithiation Performances Pyridinium-based ionic liquids (PILs-Py) possess positively charged skeleton, extended conjugated system, and regular micropores, which accelerate the migration of ions/electrons in polymer chains, benefiting the accessibility of Li+ to redox sites. PILs-Py exhibit high lithium storage capacity with “superlithiation” performance (the formation of Li6C3N3 and Li6C5N), and excellent cycling stability and superior rate capability.
