Carboxymethyl Cellulose (CMC) Micron Powder from Nanografi is a cellulose-derived polymer with a purity of ≥99.5%, intended for research and development work on lithium-ion battery anodes. It comes as a white powder with a degree of substitution of 0.6~0.9, a pH of 6.0~8.5 and a viscosity of 7000~10000 mpa.s when measured as a 2% aqueous solution.
In electrode manufacturing, CMC serves as a water-based binder and rheology modifier. By thickening the slurry it helps regulate viscosity, keeps active materials well dispersed and promotes an even electrode coating. Researchers frequently study it in graphite and silicon-containing anodes, typically paired with styrene-butadiene rubber (SBR).
Because it can be processed in water, this additive is well suited to work on aqueous electrode processing and alternative binder systems. Actual performance will vary with electrode composition, binder loading, slurry preparation conditions and the electrochemical test parameters used.
- Binder and thickening agent in graphite-based and silicon-containing lithium-ion battery anodes.
- Viscosity and consistency control in water-based electrode slurry preparation.
- Combined CMC/SBR binder systems for studying electrode adhesion, flexibility and mechanical integrity.
- Research on graphite particle dispersion, slurry stability and coating uniformity.
- Polymer binder for silicon anodes to help accommodate stresses from volume changes during cycling.
- Electrode slurry formulations for coating onto copper current collectors.
