Binder application and performance requirements

In lithium batteries, due to the low conductivity of organic electrolytes, the electrode area is large, and the choice of coil structure for battery components not only puts forward new requirements for electrode materials, but also new requirements for electrode manufacturing. The adhesive used in the process.

1. The use and function of adhesives;

(1) Ensure the uniformity and safety of the pulping of APIs;

(2) The combined use of active material particles;

(3) Adhesion between the active substance and the collection fluid;

(4) The binding effect of the active substance and the collection liquid;

(5) is conducive to the formation of SEI film on the surface of carbon material (graphite).

2. The functional requirements of the adhesive;

(1) During the drilling dehydration process, heating to 130-180℃ can maintain thermal stability;

(2) It can be soaked with organic electrolyte;

(3) Good processing function;

(4) Not flammable;

(5) the stability of i-i-CLQ, i-i -pp, 6 and by-products i-i -oh, 1,2c03 in the electrolyte;

(6) High electron ion conductivity;

(7) Low consumption and low price.
