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 announce a licensing agreement with POWER TECH

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.
YUNASKO cells are pouch type, symmetric carbon-carbon energy storage devices with organic electrolyte. These cells have been tested at independent testing labs including JME Inc. in the USA and consistently show market leading properties and durability.

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:
"We are going into production now and we are very excited about the market opportunity and our license agreement with Yunasko. The Yunasko technology is clearly superior to the best available and we plan to provide the Chinese market with a product produced in China that is competitive on both performance and price”

Vadim Utkin, CEO of Yunasko:
“We believe there is significant opportunity for Yunasko’s technology across several different markets in China like buses, renewable energy and mass transit, so expanding our partnership should provide Power Tech the opportunity to benefit from the increasing demand for ultracapacitor solutions.
In the energy storage industry, it is advantageous to establish manufacturing operations in close proximity to the customer base, so we believe ramping up a manufacturing facility in China will help us bring our solutions to market more quickly and cost-effectively.”

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.
