The core technical advantage lies in the ultra-high purity and nano-level particle size, which can form a uniform bonding network on the surface of the electrode active material, improving the conductivity of the electrode and reducing the interface resistance. It has excellent electrochemical stability within the common voltage range of lithium-ion batteries, will not decompose or react with the electrolyte, and has good thermal stability at high temperatures, improving the safety performance of the battery. It solves the problems of poor high-temperature stability and environmental pollution of traditional organic binders, and meets the high-standard requirements of new energy battery manufacturing.
The purity is ≥99.9% tested by ICP-OES, solid content is 50±1%, viscosity is 200-300 mPa·s measured by rotational viscometer, particle size D50 is ≤5μm tested by laser particle size analyzer. The bonding strength is ≥4.0MPa tested by a universal testing machine, electrochemical stability is no decomposition within 1.5-4.5V vs Li/Li+, pH value ranges from 9.0 to 10.0, heavy metal content is ≤10ppm. The product is packaged in 5kg sealed cartons, and the shelf life is 24 months when stored in a dry and airtight environment. It needs to be dispersed evenly with deionized water before use.
This product is mainly used as a binder for lithium-ion battery cathode and anode materials, and can also be used for the production of sodium-ion battery electrodes, supercapacitor electrodes and other new energy electrode products. It is suitable for lithium-ion battery manufacturing enterprises, new energy material research and development institutions, and power battery production lines, providing reliable bonding performance for high-performance new energy battery products.
