Binder-free nanocomposite for anodes via coordination-bonded nanoblending

This technology forms a binder-free nanoblended assembly through coordination bonding between transition metal oxide nanoparticles and carboxyl-modified carbon black (CCN), promoting uniform distribution of electrode components and reducing contact resistance.

Conventional slurry-based electrodes face issues such as increased resistance due to polymer binders, non-uniform distribution (agglomeration/separation) during solvent evaporation, and structural instability and resistance problems caused by insufficient interfacial interaction between metal oxides and carbon additives.

By using acid-treated, carboxyl-modified carbon black (CCN) as a conductive linker, this technology replaces organic ligands on the surface of transition metal oxides through coordination bonding. This allows for uniform assembly of components at the nanoscale, offering new design flexibility in the field of secondary battery anode materials.
