Iron/iron redox flow batteries (IRFBs) are emerging as a cost-effective alternative to traditional energy storage systems. This study investigates the impact of key operational characteristics, specifically examining how various parameters influence efficiency, stability, and capacity retention. IRFB systems with a volume of 60 mL per tank (20.25 Ah L⁻¹) demonstrated superior capacity utilization, achieving a coulombic efficiency (CE) of up to 95% and an energy efficiency (EE) of 61% over 25 charge/discharge cycles. In contrast, systems with lower capacity utilization in larger electrolyte volumes (5.67 Ah L⁻¹) required more charge/discharge cycles to reach the optimal pH-induced kinetic benefits due to increased proton content.

I have published a new review paper on experimental High-Throughput Electrochemistry: http://dx.doi.org/10.1002/celc.70190

Abstract: Experimental high-throughput electrochemistry (HTE) addresses fundamental limitations of classical electrochemical methods, which are often characterized by high manual effort, low experimental throughput, and limited reproducibility. By employing
parallelized and automated experimental systems in combination with advanced data analysis techniques such as Bayesian optimization and machine learning, the development and optimization of electrochemical processes and materials can be significantly
accelerated. Emphasis is placed on combinatorial approaches, automated laboratory platforms, and self-driving systems.

Redox flow batteries (RFBs) offer promising solutions for safe and durable stationary energy storage; however, high capital expenditures (CAPEX) hinder their commercialization.

We developed a method for low-contact-resistance welding of carbon-polymer composite plates to graphite felt electrodes and copper current collectors. Using our own extruded carbon-polymer composite plate with low carbon filling, we optimized two manufacturing methods: traditional hot-press welding and novel microwave welding.
