This innovative design offers a sustainable, safe, and high-energy-density alternative to conventional lithium-ion batteries, addressing the limitations of material scarcity and safety concerns.
With relatively low costs and a more robust supply chain than conventional lithium-ion batteries, magnesium batteries could power EVs and unlock more utility-scale energy storage, helping to shepherd more wind and solar energy into the grid. That depends on whether or not researchers can pick apart some of the technology obstacles in the way.
Non-aqueous magnesium batteries have emerged as an attractive alternative among “post-lithium-ion batteries” largely due to the intrinsic properties of the magnesium (Mg) negative electrode. Supplementary Table 1 summarizes the physical and electrochemical properties of the Mg negative electrode and other metal negative electrodes.

(A) Schematic figure of the battery mechanism: the quasi-solid-state electrolyte enhances battery performance by regulating ion storage.
Recently featured in Science Advances under the title "Next-generation magnesium-ion batteries: The quasi-solid-state approach to multivalent metal ion storage," the new Mg-ion battery has the potential to revolutionize the industry. “It is a game-changing development,” stated Professor Leung.
Besides electrolytes, the practicality of a Mg battery is also confined by the absence of high-performance electrode materials due to the intrinsically slow Mg 2+ diffusion in the solids. In this work, we demonstrated a rechargeable aqueous magnesium ion battery (AMIB) concept of high energy density, fast kinetics, and reversibility.
Aqueous magnesium batteries are plagued by a number of challenges, including low voltage, which is a potential deal breaker. Nevertheless, so far the team has achieved an energy density of 75 watt-hours per kilogram, which team leader and RMIT Distinguished Professor Tianyi Ma describes as 30% of the density of the newest Tesla EV batteries.
Magnesium batteries are potentially advantageous because they have a more robust supply chain and are more sustainable to engineer, and raw material costs may be less than state-of-the-art lithium-ion batteries.

Q: What makes magnesium-ion batteries different from lithium-ion?
Although lithium-ion batteries currently power our cell phones, laptops and electric vehicles, scientists are on the hunt for new battery chemistries that could offer increased energy, greater stability and longer lifetimes. One potential promising element that could form the basis of new batteries is magnesium.
Over the past two decades, the technical advancements made on magnesium battery electrolytes resulted in state of the art systems that primarily consist of organohalo-aluminate complexes possessing electrochemical properties that rival those observed in lithium ion batteries.
Magnesium batteries are batteries that utilize magnesium cations as charge carriers and possibly in the anode in electrochemical cells. Both non-rechargeable primary cell and rechargeable secondary cell chemistries have been investigated.
Magnesium secondary cell batteries are an active research topic as a possible replacement or improvement over lithium-ion–based battery chemistries in certain applications. A significant advantage of magnesium cells is their use of a solid magnesium anode, offering energy density higher than lithium batteries.
One potential promising element that could form the basis of new batteries is magnesium. Argonne chemist Brian Ingram is dedicated to pursuing magnesium-ion battery research. In his view, magnesium-ion batteries could one day play a major role in powering our future. Q: Why do we need to look beyond lithium-ion batteries?
