Description

Technical Field

[0001] This utility model relates to the field of carbon nanotube slurry conveying technology, and more specifically, to a carbon nanotube slurry conveying device. Background Technology

[0002] Capacitors are devices that store electrical charge and have many advantages such as fast charging and discharging speed, high specific power, long cycle life, wide operating temperature range, energy saving and environmental protection. They are currently widely used in automobiles, wind power generation, urban light rail, subways, solar energy, UPS and heavy industrial equipment. Electrodes are an important component of supercapacitors, and the quality of the electrodes directly affects the stability and service life of the supercapacitor. The electrode preparation process involves coating aluminum foil with carbon nanotube slurry using a carbon nanotube slurry delivery device. Therefore, the delivery of carbon nanotube slurry is a crucial step in the electrode coating process.

[0003] Chinese Patent Application No. 20172093329.2 discloses a carbon nanotube slurry conveying device. The device uses a pin inside an inverted conical hole to break air bubbles in the carbon nanotube slurry, allowing the gas to float into the cavity above the slide plate. However, this carbon nanotube slurry conveying device has the following shortcomings: the efficiency of breaking air bubbles in the slurry using a pin is low, and it cannot be guaranteed that the pin will fully contact the air bubbles in the slurry, resulting in poor air bubble removal.
