Decoupled Iron flow battery

This project builds upon two recent studies conducted in my laboratory. The first study explored the development of an all-iron redox flow battery and its variants, such as the iron-tungsten flow battery [1]. This design employed a conventional structure with two chambers containing the positive and negative electrolytes, using iron as the negative electrode and graphite felt as the positive electrode.

The second study focused on a metal-air battery, with zinc as the prototype metal anode [2]. This system introduced an innovative design featuring an auxiliary electrode to physically isolate the positive and negative electrodes.

This project aims to merge concepts from these two studies to develop a rechargeable iron flow battery.
