CR2032 battery

release time:2024-04-24 Hits:     Popular:AG11 battery

  What is a lithium battery separator?

  The lithium battery diaphragm is a film between the positive and negative stages of the lithium battery. When the lithium battery undergoes electrolysis, it can separate the positive and negative stages to avoid short circuit failure and at the same time allow the positive ions of the electrolyte solution to pass freely. The cost of separators accounts for about 10% of the cost of CR2032 battery. The market space is not large, and the current profit margin is between 50% and 60%, which is the largest profit margin among the four major raw materials.

  Separators are an asset-heavy field. Among the four major raw materials for CR2032 battery, investment companies have the largest production capacity and need to invest a lot of capital. Therefore, not only are there technical barriers, the purchase, adjustment, and installation of equipment usually take 2-3 years, and it takes a long time to go uphill to ensure a good product rate. There are also barriers, and there are too many depreciations in the field, and processing If the technology is outdated and the production capacity is outdated, it will be easily replaced by the market, and small and medium-sized enterprises and new enterprises will not be able to survive. Companies that have pre-emptive advantages in long-term construction will also accumulate the same advantages in terms of mid- and downstream customer verification. Because the diaphragm has a great impact on the performance and safety indicators of the battery, the verification cycle of battery manufacturers generally takes 2-3 years, and it takes about 4-6 years from entering the diaphragm industry to mass supply. , coupled with the intensive allocation of funds and iterative updates of processing technology, the advantages of first-mover leading companies have become increasingly obvious and difficult to distort.

  Lithium battery diaphragm can be produced by dry method according to its micropore plate production process (largely used in lithium iron phosphate batteries). Wet production process (largely used in ternary CR2032 battery)

  The wet overall processing process is difficult and precise. It can achieve high porosity and good breathability. It can produce diaphragms that are lightweight, high toughness, and high energy density, and is more likely to be used in downstream CR2032 battery. Lightweight, large space, high efficiency and relative energy density requirements. Therefore, with the development trend of increasing application requirements for ternary material power CR2032 battery and 3C in the middle and lower reaches, the demand for wet test diaphragms has gradually exceeded that of dry test diaphragms, increasing from about 40% in 2016 to 70% now. above. In addition, wet manufacturing uses high-pressure polyethylene, which has a low melting point and therefore weak heat resistance, which is also a common problem of ternary batteries.
