Manganese redox couples are a promising candidate for redox flow batteries due to their low cost, ecofriendliness, high standard reduction potential, and variable oxidation states.

Membranes are a critical component contributing to cost in flowing-electrolyte electrochemical systems. Flow-field-informed membrane reduction can be adopted to reduce performance compromise.

We investigated bamboo electrodes for use in vanadium redox flow batteries. The electrodes showed promising electrochemical performance, wettability, and a channel structure suitable for vanadium electrolyte flow.

An economically viable thermally annealed cation exchange membrane for polysulfide-based redox flow batteries.

This work proposes an in-plane gradient flow field design which enhances the under-rib convections for redox flow batteries. Furthermore, generalized structured approaches have been proffered for future scientific research.

Using satellite imagery we show that the installation footprint of grid-scale lithium-ion batteries is often comparable to much less energy-dense technologies such as aqueous battery systems.
