Description

HighMag is a four-year European research project, funded by the EU’s Horizon Europe programme and backed by CINEA. It brings together 13 academic and industrial partners from across Europe, Switzerland and Israel  to tackle one of the most urgent challenges in energy storage: developing sustainable alternatives to lithium-ion technology.

At the core of HighMag is a focus on Rechargeable Magnesium Batteries (RMBs) – a Generation 5 battery technology that harnesses magnesium’s natural abundance, lower cost, and enhanced safety. These attributes make RMBs a promising solution for next-generation mobility and other high-energy applications.

HighMag’s objective is to advance RMBs from Technology Readiness Level (TRL) 2 to TRL 4, through:

Developing innovative

cathode and anode

materials

Optimising essential

battery components

Applying advanced characterisation

techniques

Embedding Safe and Sustainable by Design (SSbD) principles across all research phases

Ensuring compatibility with existing lithium-ion production infrastructure to enable future industrial scalability

Through this collaborative effort, HighMag is committed to delivering a sustainable, high-performance battery solution that supports  Europe’s transition to a greener and more resilient future.

Objectives

HighMag aims to offer a sustainable and low-cost alternative to Li-ion batteries

by advancing two Generation 5 rechargeable magnesium batteries with

enhanced energies: a magnesium-sulphur battery witha conversion cathode

and a magnesium metal battery with an insertion cathode.

Work will focus on:

Developing advanced materials and components (cathode, anode, electrolyte, separator) with improved compatibility and performance.

Progressing RMB technology from TRL 2 to TRL 4 using advanced characterisation and iterative development, with pilot-scale demonstrations.

Embedding Safe and Sustainable by Design (SSbD) principles, with strong attention to safety, sustainability, and recyclability.
