When we focus on energy and energy storage applications, we will find that capacitors are "unknown heroes" in the field. As a passive device, a capacitor has two terminals that store energy and release energy when needed—often used as a “standby” power supply. In everyday life, the use of capacitors is wider than we think. For example, capacitors can be used with simple everyday items such as alarm clocks. We can also have a charging capacitor for emergency use in case of power failure. Or take the alarm clock as an example. If the power is off, the capacitor will discharge - deliver current to the clock circuit to ensure it continues to run. With the increasing use of capacitors, new capacitors are entering the market, and supercapacitors (also known as electric double layer capacitors, EDLC) are now being used on a larger scale. New energy vehicles, such as pure electric vehicles, hybrid vehicles and electric buses, rely on supercapacitors because they have much larger charge storage space than standard capacitors, and some high-power and renewable energy applications are also using supercapacitors. technology. Other applications include defense, energy, aerospace and various industrial applications.

Use of capacitors and supercapacitors

The automotive sector is a key market for capacitors and supercapacitors, and many of the functions of automobiles provide a place for capacitors. Capacitors are required for start/stop functions and power steering, and hybrid vehicles require supercapacitors with greater power capacity. As electric vehicles continue to evolve and enter the mainstream automotive market, the demand for capacitors will increase further. Future technological advances have the potential to make supercapacitors replace lithium-ion batteries as a source of power and provide mileage comparable to gasoline and even diesel-powered vehicles.

The railway industry has also begun to fully exploit the application potential of supercapacitor technology. For example, the Urbos 3 tram, manufactured by CAF, a railway company in Zaragoza, Spain, uses a series of supercapacitors located in the upper part of the cabin to recover braking energy – saving 35% of electricity. Supercapacitors can be recharged at tram stops without the need for overhead cables or between some docks without the need for cable connections.

Excellent glass-aluminum sealing performance and wide application

Aluminum electrolytic capacitors, including cutting-edge supercapacitors, are increasingly being used in emerging applications. Potential applications include new energy vehicles, high power applications, heavy industries and renewable energy. These applications impose new technical requirements on capacitors that require long-term performance. This innovative requirement is where GTAS takes advantage: the leak-proof capacitor cap can be used in different size capacitors to meet its design requirements.

The GTAS capacitor cover reduces capacitor package size by 20%, reduces capacitance loss by 60% and internal resistance by 50%. The GTAS Capsules are designed for extreme temperatures and extend product life by 10-15 years compared to organic seals.
