Enabling Aqueous Processing of Ni-Rich Layered Oxide Cathodes via Systematic Modification of Biopolymer (Polysaccharide)-Based Binders

Abstract

Biopolymer (Polysaccharide)-Based Binders

Biopolymers like polysaccharides are a F-free alternative compared to state-of-the-art polyvinylidene difluoride (PVDF), can realize water processing and be beneficial in terms of recycling. The here shown dual binder approach enables a constant viscosity of cathode slurry (i.e., similar final composite network) paving way for systematic and comparable study of sugar-based binder modifications for Ni-rich LiNi_xCo_yMn_zO₂ (NCM) cathodes.
