NOVEL BIPOLAR PLATE MATERIAL  

We have prepared our own bipolar plates to reduce stack cost and also to improve stack life time. This new material was tested in a single cell. We found that the cell resistance was slightly increased compared to commercially available graphite material. However, the cost advantage and the degradation properties of the new material are […]

SMALL SCALE SINGLE CELL QUALITY CONTROL  

We have received membranes, electrodes and bipolar plates for the production of our first prototype stacks. This material was tested in the lab in a small single cell. These experiments are necessary to make sure the material is performing according to the specified parameters. 6 experiments have been performed to verify the performance of the […]

SCALING UP RENEWABLE ENERGY: HOW RFBs OFFER A SCALABLE SOLUTION 

In the dynamic world of renewable energy, the ability to scale energy storage systems to meet growing demands is crucial. Redox-Flow Batteries (RFBs) are emerging as a scalable solution, adept at meeting the challenges of energy storage scalability.  Flexibility in Design  RFBs are uniquely flexible. Their design allows for easy scalability, meaning capacity can be […]

STACK DESIGN EVALUATION FOR INNER PERIMETER SEALING  

Follow-up to our previous article is finally here. The next step was to evaluate the design for internal leakages. Internal leakages means the cross flow from one half-cell to the other half-cell of the stack. In this experiment we used water that was pumped into one of the half cells and measured if water was […]

TESTING OF THE 5 kW BATTERY SYSTEM 

In early September, a 5 kWh redox flow battery system was successfully installed and initiated at the research laboratory at the University of Pavol Jozef Šafárik in Košice. Shortly thereafter, the Pinflow Energy Storage team conducted an insightful training session. The participants included members of the INO-HUB R&D team — Dr. Tomas Kosicky, Dr. Igor […]

PARTICIPATION IN THE CONFERENCE AT ŠTRBSKÉ PLESO

In October, we were pleased to have the honor of participating in the 7th International Conference on Novel Materials Fundamentals and Applications 2023, which took place in the High Tatras at Štrbské Pleso. The goal of this conference is to promote interactions and collaborations between researchers, educators, and industries interested in novel materials. The conference […]

THROUGH EFFICIENT AND ECONOMIC ORGANIC ELECTROLYTES SYNTHESIS 

Previous articles show the importance of discovering new and efficient organic electrolyte which could substitute the poor-available vanadium electrolyte. Even though, vanadium electrolyte presents a really competent price around (5-20 $/L) compromising the economic viability of new organic chemistries. In this sense INO-HUB R&D team and researchers from UPJS are working together in the optimization […]

ORGANIC ELECTROLYTE SET-UP 

After the synthesis of 15 new promising organic electrolytes, the basic electrochemical characterization showed promising parameters such as high redox potentials (OCV of the battery should be higher than 1.0 V), diffusion coefficients (> 10-6 cm2/s), kinetic constants (> 10-3 cm/s), and water solubility (> 1.5 M). It is time to move one step forward, […]

BRUNCH WITH BUSINESS PARTNERS AT INO-HUB HQ 

In early October, we had the pleasure of hosting a brunch at our headquarters in Bratislava, where we warmly welcomed our business partners, investors, and various institutions.   Our CEO delivered a presentation of INO-HUB’s journey, tracing our evolution from the past to the present and unveiling our visionary future.   We delved into the intricacies of […]

ORGANIC ELECTROLYTE TESTING AT UPJS 

As a part of our collaboration with the University of Pavol Jozef Šafárik (UPJS), the synthesis and testing of new aqueous soluble organic electrolytes took place.   Vanadium redox flow battery represents the state of the art because of its astonishing performance. Despite this, the poor availability of Vanadium electrolyte, the poor supply chain as well […]
