CMC is a stiff, water-soluble polymer that controls slurry viscosity and keeps graphite dispersed, but a CMC-only electrode is brittle and cracks on calendering. SBR is a soft latex that bonds particles elastically, but on its own it does not build viscosity and the slurry settles. The combination gives a coatable slurry and a flexible electrode, at roughly a third of the binder loading a PVDF system would need.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eApplications\u003c\/strong\u003e\u003c\/p\u003e\n\u003cul\u003e\n\u003cli\u003eAqueous graphite anode slurries\u003c\/li\u003e\n\u003cli\u003eSilicon and silicon–graphite anodes, where flexibility matters most\u003c\/li\u003e\n\u003cli\u003eWater-based LFP cathode slurries\u003c\/li\u003e\n\u003cli\u003eBinder loading reduction studies\u003c\/li\u003e\n\u003cli\u003eNMP-free electrode process development\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cstrong\u003eHandling\u003c\/strong\u003e\u003c\/p\u003e\n\u003cp\u003eAdd SBR last, after the CMC solution and active material are fully dispersed, and mix at low shear. High shear coagulates the latex into visible specks that will not redisperse. Do not freeze — freezing irreversibly breaks the emulsion.
