  What are the technical difficulties in 3.7 volt 18650 lithium battery separators?

  What are the difficulties in 3.7 volt 18650 lithium battery separator technology?

  Many domestic companies are trying to break through foreign technical barriers and develop 3.7 volt 18650 lithium battery separators, but it is difficult. The difficulty is mainly reflected in the following three aspects:

  First, the patents related to the traditional separator preparation process are basically monopolized by a few companies in the United States and Japan, and my country lacks independent intellectual property rights in production technology;

  Second, domestic companies are lacking in key technologies for producing 3.7 volt 18650 lithium battery separators, especially in industrialization technology. Many companies are often able to produce good samples during small trials, but the consistency of the products is poor during large-scale production;

  Third, our country keeps pace with the world in research on new processes and new methods. However, new processes often have higher requirements for equipment and process control. Our country’s foundation for precision processing equipment is relatively weak, which limits industrialization.
