Ionically Conductive Elastic Polymer Binder for Ultrahigh Loading Electrode in High-Energy-Density Lithium Batteries.

ABSTRACT: Despite the increasing demand for high-energy-density lithium batteries, the development of high-mass-loading electrodes remains challenged by structural instability and poor charge transfer. Herein, an ionically conductive elastic polymer (ICEP) binder, designed to enable the fabrication of ultrahigh mass-loading Ni-rich layered cathodes (LiNi_0.8Co_0.1Mn_0.1O₂, NCM811), is introduced. The ICEP binder integrates mechanical elasticity, strong adhesion, and ionic conductivity through diverse functional groups, addressing challenges in high-mass-loading electrode fabrication. Hydrogen bonding between the ICEP binder and NCM811 particles ensures uniform electrode morphology, forming a stable cathode-electrolyte interphase (CEI). This stable interface m
