There are many applications of batteries in our lives, and there are many types. Non-aqueous electrolyte secondary batteries are widely used in the electronic equipment market, in which sodium carboxymethyl cellulose also plays a great role, which is mainly used:
Now we often use batteries in our lives, and there are many types of batteries, of which non-aqueous electrolyte secondary batteries have been widely used in mobile phones, laptops, electric vehicles and other devices, which can be said to be widely used. This issue will introduce you to the application of sodium carboxymethyl cellulose in non-aqueous electrolyte secondary batteries.
CMC-Na, as a water-soluble dispersant and thickener, is used as a water-soluble dispersant for non-aqueous electrolyte membranes for secondary batteries, and as a non-aqueous electrolyte membrane coating solution for secondary batteries. The membranes used in non-aqueous electrolyte secondary batteries are those that have carboxymethyl ether groups in place of hydroxyl groups in the glucose residues that make up cellulose. The streaky defects on the surface of dry non-aqueous electrolyte secondary batteries produced in the diaphragm can be greatly inhibited. In addition, if there is undissolved, undissolved shrinkage after coating during the drying process, this problem can be prevented by using undissolved sodium carboxymethyl cellulose.
The generally recommended viscosity of sodium carboxymethyl cellulose is 1% aqueous solution B viscometer 100-2000mPa.s(25°C), the solution transparency is good, the gel particles are less, and the fiber is almost no.
Sodium carboxymethyl cellulose is widely used in different industries because of its performance and excellent, just like the use of non-aqueous electrolyte secondary batteries described above, which can be used in secondary batteries with its water-soluble dispersant and thickener characteristics, and can have a good application in it.
