Advances in magnesium energy storage batteries

What is a rechargeable magnesium based battery?

As a next-generation electrochemical energy storage technology, rechargeable magnesium (Mg)-based batteries have attracted wide attention because they possess a high volumetric energy density, low

Can a rechargeable magnesium battery accelerate Mg-ion storage kinetics?

This strategy provides insights into accelerating Mg-ion storage kinetics, achieving a promising performance of RMBs especially at high specific current. Rechargeable magnesium batteries offer safety, abundance, and high energy density but are limited by sluggish kinetics.

What are rechargeable magnesium batteries (RMBS)?

Benefiting from higher volumetric capacity, environmental friendliness and metallic dendrite-free magnesium (Mg) anodes, rechargeable magnesium batteries (RMBs) are of great importance to the development of energy storage technology beyond lithium-ion batteries (LIBs).

How to develop a viable magnesium battery with high energy density?

To develop viable magnesium batteries with high energy density, the electrolytes must meet a range of requirements: high ionic conductivity, wide electrochemical potential window, chemical compatibility with electrode materials and other battery components, favourable electrode-electrolyte interfacial properties and cost-effective synthesis.

Are rechargeable magnesium batteries a viable post-lithium battery system?

Provided by the Springer Nature SharedIt content-sharing initiative Rechargeable magnesium batteries (RMBs) have emerged as a highly promising post-lithium battery systems owing to their high safety, the abundant Magnesium (Mg) resources, and superior energy density. Nevertheless, the sluggish kinetics has severely limited the performance of RMBs.

What is a quasi-solid-state magnesium-ion battery?

We designed a quasi-solid-state magnesium-ion battery (QSMB) that confines the hydrogen bond network for true multivalent metal ion storage. The QSMB demonstrates an energy density of 264 W·hour kg −1, nearly five times higher than aqueous Mg-ion batteries and a voltage plateau (2.6 to 2.0 V), outperforming other Mg-ion batteries.
