A Dispersant‐Driven Carbon‐Binder Domains Homogeneity in High‐Energy‐Density Electrodes for Lithium‐Ion Batteries

Advanced Science, EarlyView.
A polar dispersant, aromatic‐functionalized polyacrylate (AFPA), enables the formation of a uniform CBD network by enhancing miscibility with PVDF and suppressing phase separation. This leads to α‐phase crystallization of PVDF and aligned CNT networks within the CBD, resulting in well‐connected structures that improve cohesion, electron/ion transport ...
