Development of high-stability manganese metal anodes via water-in-salt electrolytes for high-performance aqueous manganese ion batteries

Project description

High-stability manganese anode technologies for aqueous batteries

Advancing clean and renewable energy technologies depends on improving energy storage. Aqueous batteries, which use manganese-based anodes, offer a safer and more sustainable alternative to conventional batteries. However, these anodes suffer from stability issues, including corrosion, dendrite formation, and hydrogen evolution. Supported by the Marie Skłodowska-Curie Actions programme, the WiSE-AMIBs project aims to overcome these challenges by developing advanced water-in-salt electrolytes optimised for manganese anodes. The goal is to create high-capacity, high-energy-density batteries with enhanced safety and longevity. The project’s findings will support the development of next-generation, efficient, and safe energy storage solutions essential for the widespread adoption of renewable energy.

Objective

This project aims to develop innovative energy storage solutions by focusing on high-concentration salt electrolytes that protect manganese (Mn) anodes in aqueous batteries. Aqueous batteries, particularly those using Mn-based anodes, offer a safer and more sustainable alternative to traditional batteries, which often rely on hazardous materials and costly manufacturing processes. However, the challenge lies in enhancing the stability and performance of Mn anodes, which are prone to issues like hydrogen evolution, corrosion, and dendrite formation.
To address these challenges, the project will explore the use of advanced electrolyte formulations, specifically water-in-salt electrolytes (WiSE), which have shown promise in stabilizing multivalent metal-ion batteries. By optimizing these electrolytes and investigating the interface between the Mn anode and the electrolyte, the project aims to create a high-capacity, high-energy-density battery with enhanced safety and longevity.
This research has the potential to contribute significantly to energy storage technology, offering a pathway to safer, more efficient batteries. The findings could also play a crucial role in reducing Europe's reliance on non-renewable energy sources, aligning with broader goals of energy security and sustainability.
