TEXTURECEL™ 30000 P BA
TEXTURECEL™ 30000 P BA is a naturally derived, high-purity, high molecular weight carboxymethyl cellulose (CMC) powder that is used as a binder for graphite lithium-ion battery anodes.
TEXTURECEL™ 30000 P BA is a high molecular weight sodium carboxymethyl cellulose (CMC) that contains significantly lower levels of gel impurities than many other commercially available CMC materials. Lower levels of gel impurities present in CMC binders that are used in anode coating formulations have been found to increase the overall energy density of the battery. Therefore, TEXTURECEL™ 30000 P BA is an extremely effective CMC binder material to use in anode slurries to manufacture lithium-ion batteries.
When TEXTURECEL™ 30000 P BA is used as a binder for graphite lithium-ion battery anodes, it can improve the specific discharge capacity of the battery during very high C-Rates, enhancing charging speed. Lithium-ion batteries made with TEXTURECEL™ 30000 P BA also see increased specific discharge capacity over multiple aging cycles, indicating that lithium-ion batteries made with TEXTURECEL™ 30000 P BA CMC binders have longer battery life. TEXTURECEL™ 30000 P BA has a degree of substitution of 0.9 and forms solutions with a viscosity of 3,000–4,000 mPa·s.S at 1 wt% addition to water.
Specifications
Degree of Substitution 0.82–0.95 pH Value, 1% aqueous solution: 6.5–8.5 Total Salt Content, dry basis: 0.50 Max
Extremely low gel particle content Naturally derived anionic polymer Readily water-soluble Improved thickening properties Can be mixed with solids Wide range of pH stability
Problems Solved
High gel impurities present in low-quality carboxymethyl cellulose binders Fast decay of lithium-ion battery life over numerous battery charge cycles Slow charging speed of lithium-ion batteries Low energy density of batteries
