Ashland Specialty Ingredients offers three Aqualon CMC grades for effective anode slurry preparation. Aqualon Aqu D-5283 CMC offers outstanding slurry stability for stable processing and easy dissolution in water for fast processing. Aqualon Aqu D-5139 CMC offers good slurry rheology for stable processing, and both grades enhance adhesion of graphite to the anode for longer cell life. The electrochemical characteristics of Aqualon Aqu D-5284 CMC are optimized for use with Mesophase Artificial Graphite in the cell.
Ashland provides CMC under the tradenames Aqualonâ„¢ CMC and Blanoseâ„¢ CMC depending on site of manufacture. Since its commercial introduction in the United States in 1946, Aqualonâ„¢ sodium carboxymethylcellulose has found use in an ever-increasing number of applications. The many important functions provided by this polymer make it a preferred thickener, suspending aid, stabilizer, binder and film-former in a growing variety of applications.
Aqualonâ„¢ and Blanoseâ„¢ MC are anionic, water-soluble polymers. CMC is made by reacting alkali cellulose with sodium monochloroacetate under rigidly controlled conditions. Physical and solution properties of CMC can be varied through manipulation of degree of substitution and molecular weight. CMC is typically offered in three different DS ranges and a broad range of molecular weights. A variety of CMC grades are available to meet your formulation needs.
The anionic nature of CMC allows it to interact with the positive charges found on protein in acidic conditions, thus making it an excellent stabilizer for low-pH dairy beverages. Add Aqualon aqueous binders for effective anode slurry preparation and graphite binding Aqualon carboxy methyl cellulose products perform as both aqueous binders and rheology modifiers. These CMC products are typically used in conjunction with styrene butadiene latex to improve the binding strength of the active graphite on the copper collector. SB alone cannot generate slurry stability for the graphite powder.
The CMCs improve the rheology characteristics and allow sufficient coating of the copper foil at high speeds, ensuring the lithium ion cells survive multiple discharge cycles. In the manufacturing process, the greater-than-99. 5 percent purity Aqualon CMCs ensure excellent dispersion of graphite particles; homogeneous distribution of the binder, and high coating quality.

Aqualonâ„¢ cellulose gum, or sodium carboxymethylcellulose, is widely used as an economical thickener and stabilizer in foods and beverages. Aqualon cellulose gum has the ability to form strong, oil-resistant films. In beverage concentrates (alcoholic and non-alcoholic) and powdered drink mixes, cellulose gum adds pleasant, clean mouthfeel.
Aqualonâ„¢ sodium carboxymethylcellulose is made by reacting sodium monochloroacetate with alkalicellulose under rigidly controlled conditions. Aqualon CMC is an anionic, water-soluble polymer. Aqualon CMC grades designated P or PH are compliant with the monograph requirements of the National Formulary. Ashland provides cellulose gum under the trade names Aqualon, Blanoseâ„¢ and Bondwellâ„¢ depending on the zona in which we serve you.
In addition, they generate defect-free electrodes from a water-based slurry. In the cell, the CMCs are compatible with both natural and synthetic graphite and standard latex co-binders. In-cell, the electrochemistry performance ensures effective electrolyte penetration, high charge capacity, coulombic efficiency and good cycle performance with high capacity retention.
