New paper published – Development of high-performance and cost-effective electrode assembly for redox flow batteries

Richtr et al. 2025

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.

Elaine Sum at 40th VRFB Anniversary in Sydney

On October 15-16, 2024, the 40th anniversary symposium was held in Sydney in honor of the discovery of the Vanadium Flow Battery. I was able to meet Elaine Sum at this event and unfortunately only spoke briefly. Elaine was the first person at UNSW to work on the topic. Based on her work, the potential for the feasibility of a vanadium flow battery was seen.

PREDICTOR KickOff Meeting

The kickoff meeting for the PREDICTOR project took place at the Fraunhofer ICT on 19.09.24. PREDICTOR is an EU Marie Sklodowska-Curie training network of 17 PhD students on computational and experimental high-throughput methods in the field of electrochemistry for redox-flow batteries. The objective is the development and demonstration of novel organic redox-flow batteries.
