CMC Sodium Is Widely Used in Lithium Battery Production

CMC Sodium Is Widely Used in Lithium Battery Production

1. CMC sodium is widely used in the production of lithium batteries

CMC sodium (CMC) as a stabilizer and binder 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.

2. The thermal stability of CMC sodium

When the temperature reaches 300 degrees, CMC-lithium is rapidly decomposed, and the mass is reduced by 70%. When it reaches 400 degrees, the mass is reduced by 10% on this basis. CMC-lithium is easy to decompose at the end of battery life.

3. Electrochemical performance of CMC sodium

CMC sodium material as a binder can be used in different types of electrode materials such as natural graphite, mesocarbon microspheres (MCMB), lithium titanate, tin-based silicon-based anode materials, and lithium iron phosphate cathode materials. It can improve battery capacity, cycle stability, and cycle life compared to when using PYDF. Because CMC has good thermal stability, electrical conductivity, and electrochemical properties.

4. There are two main mechanisms for improving the performance of lithium ion batteries by CMC sodium:

1) The bonding performance of CMC is stable;

2) CMC has good electronic and ionic conductivity, and it can promote the transfer of lithium.

The above are the various characteristics and advantages of CMC sodium used in the production of lithium batteries.
