Interplay of Adsorbed and Free Polymer Governs Microstructure and Processability of Battery Slurries
In Li-ion battery anodes, sodium carboxymethyl cellulose (CMC) serves as an indispensable binder despite its minimal electrochemical contribution. Even at low concentrations, CMC imparts colloidal stability, ensures adequate flow during coating, and promotes uniform distribution of active materials. Within the slurry,...
