YUNASKO ultracapacitors operating at 100°C enable new applications
Thursday, 16 February 2017
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.
YUNASKO is now looking for an industrial partner for collaborative product development and market adoption. About YUNASKO: YUNASKO is currently the global technology leader in the field of high-power carbon-carbon ultracapacitors and lithium-ion capacitors. YUNASKO is headquartered in London, UK, where all intellectual property is managed. Management and technical teams are based in Kyiv, Ukraine. Main expertise of YUNASKO technical team includes electrochemistry, material science, process engineering, and electrical system design. About JME: JME is headed by Dr. John R. Miller, a recognized expert in ultracapacitor technology and metrics. JME is known for providing independent expert evaluation services of various ultracapacitor technologies for the U.S. Air Force and other customers. Dr. Miller co-authored the first ultracapacitor manuals in 1994 and chaired many energy storage focused forums over the past two decades. Press contacts: Vadim Utkin, CEO.

Tuesday, 27 January 2015
KYIV, UKRAINE and HEBI, CHINA, January 2015. YUNASKO, a leader in research, development and manufacturing of ultracapacitor products, announce a licensing agreement with POWER TECH for the manufacturing and sales of high-performance ultracapacitors cells and ultracapacitor modules. YUNASKO and POWER TECH announced that they have entered into a license agreement and under the terms of the agreement, YUNASKO will license ultracapacitor technology for use in public transportation i.e. hybrid new energy buses and vehicles, subways, trams and railroads and similar applications. Dr. John R. Miller, head and founder of JME, Inc. comments on the testing results from his laboratory: "Measured life for the YUNASKO ultracapacitors exceeded manufacturer’s specifications. Cells have been designed to have minimum ESR and these cells have the lowest DC resistance and exhibit the highest charge/discharge efficiency. The pilot production YUNASKO capacitors exhibited the longest life in terms of capacitance retention. Even with tripling of resistance these capacitors still have very low resistance values." POWER TECH has constructed a 10,000 square meter ultracapacitor manufacturing facility in Hebi City in the Chinese province of Henan, to meet the growing demand for energy storage in China. Power Tech will manufacture ultracapacitor cells and modules utilizing the proven YUNASKO technology. Sample products will be provided to potential customers for evaluation during the first half of 2015. Peer Nielsen, CEO of Power Tech: Vadim Utkin, CEO of Yunasko: About POWER TECH: PowerTech New Energy Co. Ltd. is a subsidiary of one of the leading and oldest film and tantalum capacitor factories in China with a sole focus on ultracapacitor manufacturing and sales. Power Tech is closely associated with the largest private university in China, Huanghe Science and Technology College based in Zhengzhou, Henan Province in the center of China. About YUNASKO: Yunasko is a developer of proprietary ultracapacitor technology that is addressing the needs for highly reliable and power performance energy storage. This technology is ready for the large scale manufacturing by world-class electronics manufactures. Ultracapacitors can be used in a broad variety of applications, ranging from vehicles, heavy industrial machinery and smart grids to consumer electronics. Press contacts: Yunasko: Vadim Utkin, CEO.
