YUNASKO ultracapacitors operating at 100°C enable new applications

YUNASKO recently completed independent tests at JME (Cleveland, USA) of a proprietary high-temperature ultracapacitor system with -25°C to +100°C operating temperature range. Test results confirmed the stable performance of YUNASKO high-temperature ultracapacitors that successfully passed endurance tests at +100°C for 2,000 hours, which normally corresponds to the cycle life as long as million of charge-discharge cycles and ensures the high reliability of YUNASKO solution.

Independent tests also determined the operating voltage ratings of YUNASKO high-temperature ultracapacitors as 2.39 at +100°C. This is the highest operating voltage of any solution-based ultracapacitor, even higher than ionic liquids (about 2.0V), at a fraction of the cost typically seen for ionic liquids. The maximum operating voltage for the YUNASKO system is 3.0V at +25°C. Another advantage of YUNASKO high-temperature ultracapacitors is their high power output at both +25°C (up to 25 kW/kg) and +100°C (up to 34 kW/kg).

Superior performance of YUNASKO high-temperature system enables new ultracapacitor applications in automotive (location near the engine), well drilling equipment, power electronics (near circuit board hot spots) or in hot climate regions.

Dr. Natalia Stryzhakova, head of YUNASKO R&D lab comments on the testing of YUNASKO high-temperature ultracapacitors:

“We have been working on this challenging project for two years testing many electrolytes, and now we are happy to get a low cost ultracapacitor system capable of reliably working at temperatures as high as 100-110°C with excellent low-temperature performance”.

YUNASKO is now looking for an industrial partner for collaborative product development and market adoption.

YUNASKO was selected together with 30 companies to present its technology at Global Cleantech Summit 2016 in Beijing on 23-24 March 2016.

The Global Cleantech Summit 2016: “The Accelerator 100 Project” showcased 100 clean technologies from China and around the world, provided timely analysis of the 13th Five Years Plan and insights into its implications to the cleantech sector development and market opportunities in China. The Summit convened businesses, experts, academia and government representatives, and provided a collaboration platform to facilitate investments and deployment of clean technologies. 

Companies were examined on the uniqueness of their technology, the strength of their business model, vision, and capability to execute on the business plan by investor panelists who were invited to listen presentations. The Cleantech Summit provided an excellent networking area where technology leaders, entrepreneurs, venture capitalists and government officials could discuss the recent cleantech market developments and find topics for the further cooperation.
