YUNASKO took part in EESAT 2017 conference in San Diego, California

YUNASKO recently participated in Electrical Energy Storage Applications and Technologies (EESAT) conference in San Diego, CA during October 11-13, 2017.

EESAT is the premier energy storage technical meeting which has proven to be at the international forefront of advancing leading-edge research, development, and deployment of energy storage ideas, projects and challenges. The 2017 EESAT theme is “Energy Storage Evolution and Revolution”. This year’s meeting provides a format to revisit critical, turning point research coupled with new frontiers in technology development and emerging applications for the smarter modern electricity grid.

Dr. Sergii Tychina, YUNASKO new business development manager presented company’s approaches to improve performance of ultracapacitors, namely increasing energy and power densities.

Increase in power density was obtained due to a number of improvements including an approach based on studying the electrolyte in-pore mobility in positive and negative electrodes. It enables to substantially increase the ultracapacitor power output to about 100 kW/kg and efficiency to over 99.0%.

However, the low energy density is still a weak point of all the ultracapacitors that does close many doors to the market. An increase in energy has been achieved due to so-called parallel hybridization of the electrode/electrolyte system, wherein both positive and negative electrodes contain nanoporous carbon and Li-intercalated metal oxides as balanced mixtures.

YUNASKO was selected to participate in invest forum at EXPO-2017 in Astana, Kazakhstan

30 projects from around the world, 5 projects from Ukraine among them, were selected for participation in the invest-forum in the framework of EXPO-2017 in Astana, Kazakhstan in August 2017.  Yunasko project was one of five selected, and in a short pitch we presented two of our technologies: (a) carbon-carbon supercapacitors demonstrating the highest power capability and efficiency, and (b) hybrid technology that provides by far the largest energy than other hybrids (35 Wh/kg against 12 Wh/kg), and also demonstrates a quick charge rate – it can be fully charged within 3 min. A few promising contacts were established during the forum.

YUNASKO participated in the Workshop Graphene-enhanced supercapacitors

On July 4th 2017 YUNASKO participated in the Workshop Graphene-enhanced supercapacitors: Application perspectives within forklifts, which took place at The Squaire in Frankfurt.  

The workshop was organised by the Fraunhofer Institute for Systems and Innovation Research ISI in context of the 'Graphene Flagship' (https://graphene-flagship.eu) and the 'Graphene Technology & Innovation Roadmap’. The aim of the workshop was to explore market potentials and demands for selected applications that promise highest competitive advantages for the European economy. The workshop analysed the potential for a future value chain comprising graphene production for advanced supercapacitors to power forklifts.  

Key topics included:  
• Energy supply of forklifts: What is the state-of-the-art? What are key parameters for the development of alternative technologies? What are desires and requests to enable competitive advantages?  
• Supercapacitors: What is the current state-of-the-art? Can graphene implementation enhance their performance? On what extent? On what timescale? At what cost?  
• Graphene: What are the specific material properties required for supercapacitors? What are appropriate manufacturing techniques promising sufficient material quality and production volume?  

The discussion appeared to be productive. In an open discussion, leading research and industry experts representing all relevant European stakeholder groups along the innovation chain evaluated the technological and economic opportunities and challenges. More official workshop results will be published by Fraunhofer ISI soon.
