High specific power

The ability to rapidly accumulate and provide energy makes ultracapacitors unique in high power and regenerative braking applications. Additionally, ultracapacitors are extremely efficient energy storage devices with 80-95 % efficiency, even under high load conditions.

High power and normal energy densities fill the gap between standard batteries and traditional capacitors for high-power, short-duration energy storage. The basic ultracapacitor technology, which is scalable in the cell form, is also scalable in module form, and ultracapacitor modules are now being configured for high-voltage, high-power applications. The flexibility and scalable nature of ultracapacitor technology enables a wide range of applications that directly interface with power-conversion systems, including DC-to-DC boost converters and DC-to-AC inverters.

Safety in Operation

Compared to lithium and lead based high power battery chemistries, ultracapacitors inherently eliminate the risk of self ignitionor explosion. As shown in nail test video, an ultracapacitor sample operated safely even after the full nail penetration. The extreme over-voltage conditions also provide no hazard risk.

Long Lifetime

Typical ultracapacitor lifetime is about 10-20 years and 500 000 – 1 000 000 charge/discharge cycles. The have a low rate of degradation in performance even after hundreds of thousands of charge/discharge cycles. An increase in the operating temperature or voltage reduces the lifetime. So it is important to keep the correct operation conditions for the ultracapacitors according to the specifications.

Wide temperature range

Ultracapacitors are typically working normally in -40C +70C temperature range. The special electrolyte can be also selected in order to extend the temperature range either below -40C or higher than +100C.

Maintenance free operation

Ultracapacitor modules are maintenance-free. For instance, once installed into an UPS system, they require no additional maintenance and have very simple monitoring.

Environmentally friendly

Ultracapacitors are environmentally-friendly because they do not contain hazardous or hard-to-recycle materials. Materials used in the ultracapacitor cells are mainly activated carbon, aluminum-based materials, polymers and some organic electrolytes.
