Product Description

Carbonized paste for lithium battery cathode current collector: BH-8811

Product introduction: This product uses ultra-fine conductive carbon black + ultra-thin conductive graphite sheet as the main material to reduce polarization and improve the electrochemical performance of the battery. It is suitable for aluminum foil with low dyne value, and is used for the pretreatment of aluminum foil for battery cathode current collector.

Product Features:

1. Stronger adhesion to lithium iron phosphate active materials

2. Good wettability to substrates

3. Good solvent resistance

4. The coating carbon material is easy to disperse and the particle size is controllable. Good storage stability of the paint

5. Low coating resistance

6. The coating is evenly applied and will not be missed.

Application recommendation: Lithium-ion batteries, sodium-ion

Suggested usage and precautions

1. Printing and coating directly on the machine, and the aluminum foil is coated after degreasing and corona treatment.

2. When printing and coating, it is recommended that the temperature of the lower oven be set to 100°C-110°C-110°C-110°C-normal temperature; The upper oven temperature is set to 90°C-100°C-100°C-100°C-100°C-90°C-room temperature; The speed of the vehicle does not exceed 80-180 m/min.

3. It is recommended to store in a cool place (below 25°C), tightly sealed, and avoid direct sunlight

Packing: Plastic drum, net weight 50 kg.
