Super Capacitor Division    

The SuperCapacitor Business Unit was established in 2017. It has gathered a professional team integrating new product development, high-precision manufacturing, and application end promotion. It has made every effort to introduce foreign high-quality materials and technology, forming a highly matching product technology system. Now we have a full range of Ultracapacitors at home and abroad, such as cylindrical lead type, horn type, button type, module type, SMD chip type, 3.8V lithium ion capacitor, etc. The products meet the national grid certification, AEC-Q200, IATF16949, etc. A number of certifications, widely used in smart three-meter (electric meter, water meter, gas meter), automotive electronics (ETC, driving recorder), new energy (wind pitch, photovoltaic), military industry (tank emergency start power supply) and other industries. With the rapid development of 5G technology and the smart Internet of Things market, the products of the supercapacitors business unit will continue to inject development momentum into smart life and bring users a better experience.

What is supercapacitor

Supercapacitor,we also call it such as ultracapacitors and Electric double layer capacitor. A supercapacitor is an energy storage device in the all types of electrolytic capacitor.that can store large amounts of energy and discharge it quickly. It has a high power density and is capable of charging and discharging thousands of times faster than a traditional battery. Ultracapacitors are becoming increasingly popular due to their long lifespan and ability to store large amounts of energy.

Composition of Supercapacitor.

Supercapacitors are composed of two electrodes, an electrolyte, and a separator,It’s the electrolytic capacitors that with High energy, high power, large capacitance, super long charge and discharge life. The electrodes are usually made of carbon materials, while the electrolyte is mostly an ionic liquid or an organic electrolyte. The separator is usually a porous material that keeps the two electrodes from coming into contact. The electrodes of a ultracapacitor store energy by forming a double-layer of charge on their surface, which is supplied by the electrolyte. The separator prevents shorting between the electrodes.

How's the Ultracapacitor Work ?

When a voltage is applied across the electrodes, electrons flow from the negative electrode to the positive electrode and back again, creating an electric double-layer. This double-layer stores energy, which can be released when the voltage is reversed. The separator prevents the electrodes from coming into direct contact and shorting out, so the electric double-layer can be maintained.

Application of Supercapacitor.

Supercapacitors are used in a variety of applications, from electric vehicles to energy storage systems. The ultracapaitors can also be used to provide short bursts of energy for starting engines or for power spikes in electronics.

This stored energy can then be used to power devices or machines, such as electric vehicles or power tools. Supercapacitors are highly efficient, reliable, and have a long lifespan. They are also easy to recharge and can be used in a variety of applications.

This energy can be used to power a wide range of devices, from small consumer electronics to larger industrial machines. Supercapacitors are becoming increasingly popular due to their ability to store and quickly release energy.

The supercapacitor is used in a variety of fields including automotive, renewable energy, consumer electronics, and more. It is an ideal energy storage device due to its high power density, long cycle life, and low maintenance cost.

This energy can be used in a wide range of applications, such as providing power to electronic devices and starting a car engine. Supercapacitors are also used in energy storage systems, such as solar grids, to store and release energy as needed.
