Purity (active CMccontent) |
inevitably CiC powder is produced with by products that are sodium salts which comes in the product SodiumCarboxymethyl Cellulose content in the product is the purity. |
Viscosity |
one of the most interesting characteristics of the CMC powder is the viscosity which can be from low to high. lt ismeasured mostly by digital viscometers at certain temperatures in diferent solution rates; such as 1%, 2% or 4% |
Degree of Substituion | is the average number of sodium carboxymethyl groups per anhydroglucose unit on the cellulose back bone. Thisparameter in some application areas is quite important to control in the product. |
Physical form |
the CMC powder can be produced in fine powder to dust-free granule. |

Applications in batteries
1. To enhance the stability and mobility of non-hydrophilic materials dispersed in the solvent. 2. To disperse negative electrode active materials and conductors;
2. Dispersion of negative electrode reactive materials and conductors;
3. Bonding to protect the active material;
4. Preventing deposition of reactive substances;
5. Stabilizing electrode working performance;
6. Stabilizing the electrode structure and enhancing the charging and discharging strength of the stripped cell with highly improved electrodes.
Sentai CMC Product Features
1.Improve slurry sedimentation. compared to other CMc slurries, the stabilily is significantly enhanced. in a 72-hour standingtest with continuous observation, the stability showed minimal changes.
2.Excellent screen passage rate. Sentai CMc has fewer impurity particles, and after dissolution, insoluble substances are almostentirely eliminated.
3.Address electrode cracking. Compared to other CMCs, Sentei CMc provides better electrode flexibility, effectively resolving
crackingissues.
4.Reduce surface defects on electrodes. Strict control over solid insoluble substances can resolve electrode defects caused by
CMC.
5.Low dosage requlremen. The dosage range is 0.8%-1.5%, and users can select diflerent models based on dispersion
effectiveness.
6.Good product compatibility.It can be usedin combination with materials such as SBR and PAA.
