Cekol® carboxy methyl cellulose (CMC) binders for battery applications

Our Cekol® CMC enhances lithium-ion battery performance when used as a binder in anodes or for separator reinforcement.

To improve battery performance, our Cekol® CMC can be coupled with SBR latex and applied as a binder in the anode to create a strong copper collector as well as a ceramic binder to reinforce the separator and prevent dendrite penetration.

Cekol

The innovative Cekol® sodium carboxymethyl cellulose (CMC) is a bio-based and biodegradable hydrocolloid, making it a preferred sustainable choice. The grades and functionality of the CMC can be tailored for specific uses such as for battery, pharmaceutical, food, and personal care applications. Cekol® CMC is a water-soluble polymer derived from wood or cotton cellulose and produced to a minimum of 99.5% purity. The product hydrates and dissolves readily in hot and cold water and, as it is manufactured from wood cellulose, it fulfills GMO-free requirements. By choosing the right type of Cekol® CMC, formulators can achieve the desired rheology for any aqueous system, including suspensions and emulsions. In addition to controlling the rheology, Cekol® CMC is known for its excellent water retaining and film forming capacity.
