Product introduction:
This product is a new type of current collector that uniformly coats the surface of aluminum foil with a graphene coating. This product utilizes the excellent conductivity and two-dimensional sheet structure of graphene to form an ultra-thin coating (thickness less than 1um) with excellent conductivity on the surface of the current collector, which can significantly reduce the interface resistance and increase the adhesion of the active material. Improve battery rate performance and cycle life. Its comprehensive performance is superior to the application of ordinary carbon black and graphite modified coated aluminum foil, which can replace traditional aluminum foil and corroded aluminum foil in lithium ion batteries and supercapacitors.
Specifications:
Name: Graphene coated aluminum foil current collector
Appearance: black gray coating
Coating double-sided thickness (typical): 0.6um
Double-sided surface of the coating: 0.04~0.1/mg.cm(-2)
Product Features:
1. This product uses graphene as raw material to achieve ultra-thin coating.
2. Can significantly reduce the interface resistance, improve the lithium battery‘s rate, cycle and other electrochemical properties.
3. Improve the adhesion between the active material and the current collector, inhibit the corrosion of the current collector, and prolong the cycle life of the battery.
4. Reduce polarization, reduce thermal effects, suppress temperature rise during charging, and improve battery safety.
Recommendations:
1. This product can be used directly as a current collector in lithium ion batteries or supercapacitors.
2. The product is suitable for various coating methods (such as continuous coating, gap coating, etc.). When the coating operation is performed, the temperature of the tail of the machine head is controlled to be less than 30%.
3. When using ultrasonic ear soldering, it is recommended to use 10% higher power than ordinary aluminum foil, and the ear riveting is not affected.
4. This product is easy to absorb moisture. Do not open the vacuum packaging before use. If there is any residual material after use, it is recommended to dry it in a vacuum drying oven (40-60 °C) for 2 hours and then vacuum dry.
