The binder binder requires special lithium battery, many varieties, PVDF is the mainstream. The binder is essential for manufacturing electrode materials must meet many special requirements, PVDF is currently the most commonly used in industrial lithium ion battery electrode binder, in order to overcome the oil-based binder of environmental pollution and the use of high cost of the problem, the water soluble binder has been developed. The weak competitiveness of domestic manufacturers of products, adhesive market by foreign enterprises control.
