Carboxymethyl Cellulose is widely used in lithium battery production

Jan. 11, 2020

As a stabilizer and binder, CMC can be used to make electrode materials, which can avoid the use of NMP, reduce costs and reduce environmental pollution; it can also increase battery capacity and extend cycle life.

Thermal stability of CMC

When the temperature reaches 300 degrees, CMC-lithium decomposes rapidly, and the mass is reduced by 70%. At 400 degrees, the mass is reduced by another 10%. CMC-lithium is easily decomposed at the end of battery life.

Electrochemical properties of CMC

As a binder, CMC materials can be used in different types of electrode materials such as natural graphite, mesh carbon microspheres (MCMB), lithium titanate, tin-based silicon-based anode materials, and lithium iron phosphate anode materials. Cycle stability and cycle life have been improved compared to when using PYDF. Because CMC has better thermal stability, electrical conductivity, and electrochemical characteristics.

As a CMC Powder Supplier, share with you.

There are two main mechanisms by which CMC improves the performance of lithium-ion batteries:

1) The bonding performance of CMC is stable;

2) CMC has good electronic and ionic conductivity and can promote lithium transfer;

Carboxymethyl Cellulose

Carboxymethyl Cellulose

Carboxymethyl Cellulose is an excellent detergent-grade suspension and dispersant. It can be widely used in phosphate-free detergents, detergents, detergents, soaps and other fields. Because of its excellent anti-redeposition properties, CMC is widely used as a washing aid.

The specific principle is that the detergent or soap added with CMC can make the dirt entering the aqueous solution dispersed and suspended so that it can prevent the dirt from settling on the clothes, and the strong decontamination ability can effectively reduce the washing time. It can better maintain the cleanliness of clothes, and at the same time can effectively maintain the color of clothes. Washed clothes will be softer and more comfortable. The effect is more pronounced in hard water using CMC-added detergents.

The quality problems that often occur in acid milk beverages are mainly precipitation and oil slicks. At low pH conditions, milk products will condense and precipitate. At this time, CMC, as a good stabilizer, can form a colloidal solution with proteins, which can organize the occurrence of such agglomeration and precipitation.

In order to improve stability, you can start by improving some technical indicators of CMC, which is convenient and quick.

First of all, we must ensure that CMC has good acid and salt resistance. This requires CMC to have a very good substitution uniformity, that is, a high degree of substitution.

Secondly, the corresponding viscosity should be accurately selected according to the taste and thick effect of the beverage.

Our company also has Copper Sulphate on sale, welcome to consult.
