Batteries and Fuel Cells

A battery is a galvanic cell that is used as a source of electrical power for specific applications. Modern batteries exist in a multitude of forms to accommodate various applications, from tiny button batteries such as those that power wristwatches to the very large batteries used to supply backup energy to municipal power grids. Some batteries are designed for single-use applications and cannot be recharged (primary cells), while others are based on conveniently reversible cell reactions that...

Background:

Magnesium-air batteries offer high energy density and safety.
Rapid passivation of magnesium anodes hinders their practical application.

Purpose of the Study:

To develop a strategy to overcome passivation in magnesium-air batteries.
To enhance the kinetics and stability of magnesium anodes under high current densities.

Main Methods:

An in situ hydrogenation strategy was employed to embed cerium hydride (CeH2.73) nanodomains within magnesium.
The hydride-oxide conversion mechanism was investigated during battery discharge.
Performance was evaluated under ultrahigh current densities and varying temperatures (0 °C, 80 °C).

Main Results:

The CeH2.73 nanodomains reprogrammed magnesium dissolution from localized corrosion to a uniform mode.
A dynamic hydride-oxide conversion prevented passivation, enabling rapid interfacial turnover and efficient ion/electron transport.
The CeH2.73|Mg anode achieved an energy density of 396 Wh kg-1 and peak power density of 140 mW cm-2 at 200 mA cm-2.
Stable operation was demonstrated across a wide temperature range and in low-oxygen seawater environments.

Conclusions:

Hydride phase engineering is a generalizable strategy for high-power, wide-temperature metal-air energy systems.
The developed anode exhibits superior performance for demanding applications, including seawater batteries.
