CHARACTERIZATION OF ORGANIC ELECTROLYTES FOR RFB APPLICATIONS
After synthesizing a variety of organic electrolytes, the next crucial step is to characterize their electrochemical properties. This includes evaluating parameters such as the kinetic constant, the diffusion rates of charged and uncharged species, and their solubility in water. These factors determine the feasibility of implementing the organic molecules in a redox flow battery (RFB). […]
CHARAKTERIZÁCIA ORGANICKÝCH ELEKTROLYTOV PRE RFB APLIKÁCIE
Po syntéze rôznych organických elektrolytov je ďalším rozhodujúcim krokom charakterizácia ich elektrochemických vlastností. Patrí sem vyhodnotenie parametrov ako je kinetická konštanta, rýchlosť difúzie nabitých a nenabitých látok a ich rozpustnosť vo vode. Tieto faktory určujú potenciál využiteľnosti týchto organických zlúčenín v redoxných prietokových batériách (RFB). Pre dosiahnutie tohto kroku sa syntetizované zlúčeniny analyzovali pomocou meraní […]
INOHUB ENERGY AND THE DEVELOPMENT OF AQUEOUS-SOLUBLE ORGANIC ELECTROLYTES FOR RFBs
At INO-HUB Energy, we are deeply committed to developing innovative electrolyte alternatives based on aqueous-soluble redox-active organic molecules. Organic chemistry unlocks the potential for creating electrolytes from earth-abundant elements, fostering sustainable and environmentally friendly solutions. One of the key advantages of these organic molecules is their high tunability. Their electrochemical properties—such as redox potential, solubility, […]
STACK DESIGN
The design of a new stack is a challenging task in itself. The first decision was weather we want to build a simple and cheap stacks or a more sophisticated stacks with higher power output. We decided to do the latter. Meaning that the power density of the stack should be at least 200mW/cm2 of […]
LABORATORY CELL DESIGN AND OPTIMIZATION
For the evaluation of different materials e.g. membranes and electrodes we decided to design our own laboratory cell. The first design was supposed to be easy to manufacture and should be versatile enough to test all required materials and electrolytes. Therefore, we chose a design that would allow us to use different thicknesses of membranes […]
OPTIMIZATION OF THE BATTERY DESIGN – PRESSURE DROP SIMULATIONS
The production of every battery cell, regardless of its size, starts from the inception of models of all components. Then, utilizing modern software, we model the future cell behavior before the actual production of parts and ordering of the materials. The first battery parameter that could be evaluated from the model is the pressure drop […]
EVALUATION OF THE SMALL CELL PARAMETERS – PRESSURE DROP TESTS
The primary parameters of the redox flow batteries are Coulombic Efficiency (the ratio of the discharge and charge capacities of the same cycle), Voltage Efficiency (the ratio between the battery voltage during the charging and discharging), and Energy Efficiency (the measure of energy loss in a charge-discharge cycle). All these parameters are related to the […]
LABORATORY LONG-TERM REDOX FLOW BATTERY TESTING
Every groundbreaking technology starts from lab experiments. Assembling the small redox flow battery cells offers an opportunity to test all battery components, such as membranes, bipolar plates, sealings, and electrode materials, as well as the cell’s overall design. The insights gained from these tests pave the way for the application of proven materials in larger […]
