Ioxus, a manufacturer of ultracapacitor technology for transportation, alternative energy, medical, industrial and consumer product markets, has developed a hybrid capacitor, a combination of an ultracapacitor and a lithium-ion battery, with an increased energy density.

The hybrid capacitor is claimed to provide an energy density that is 115% higher than standard electric double-layer capacitors (EDLCs) and has been designed to offer more than 20,000 charge/discharge cycles.

While offering advantages over standard ultracapacitors, which have an energy density of 12.8Wh/L, the Ioxus hybrid capacitor delivers an enhanced capability of energy storage, is believed to power applications more quickly and offer 90 to 95% efficiency.

Ioxus’ hybrid capacitor operates in temperature range of -25 degree centigrade to +60 degree centigrade and loses only 5% of its energy at the low end of the range, while comparable battery energy loss would by 50% or more.

The Ioxus’ hybrid capacitor can be used for various purposes like flashlights, LED applications, memory back-up, portable hand tools, solar charge applications, off-grid lighting and automotive subsystems such as power windows and door locks.
