Some examples of atomically-dispersed inert elements include, but are not limited to, hydrogen (H), carbon (C), nitrogen (N), and chlorine (Cl).

Conducting Polymer-Based Electrode Matrices for Lithium-Ion Batteries

Resumen de: US2025125362A1

Polypyrrole:carboxymethyl cellulose (PPy:CMC) composites were synthesized by in situ chemical oxidative polymerization. Following that, carbon-additive-free LiCoO2/PPy:CMC cathodes were fabricated by using water as a processing solvent. Carbon-additive-free cathodes were then cycled to study the performance of PPy:CMC electrode matrices. The results indicate that PPy:CMC composites were electrochemically stable within the cathode operating voltage window. As the cycle number increased, electrolyte anions became dopants for PPy units in PPy:CMC composites. The sharp spike in cell voltage of LiCoO2/PPy:CMC cathodes in the first charging cycle indicated that undoped/neutral PPy units in PPy:CMC composite were oxidized and doped to become fully conductive. This unique phenomena teaches an activation procedure for using other CP-based electrode matrices in Li-ion batteries such as polyaniline:carboxy methyl cellulose (PANI:CMC) composites.
