metal-air battery

However, metal-air batteries have high specific energy because the cathode is provided by the surrounding oxygen in the air.

ILs can replace water as the electrolyte in metal-air batteries.

Metal-air batteries, specifically zinc-air, have received attention due to potentially high energy densities.

Metal-air batteries offer a possible low-cost solution.

The theoretical specific energy densities for metal-air batteries are higher than for ion-based approaches.

Fluidic earned one of those grants, with Friesen as the principal investigator, for its work with metal-air battery technology.

"These findings could help forge a path between nanostructured-carbon-based materials and alkaline fuel cells, metal-air batteries and certain electrolyzers," said Zelenay.

The electrocatalytic activity of heteroatom-doped carbon-based nanomaterials has become a growing interest in the past few years due to their potential applications for fuel cells and metal-air batteries.

Ruddlesden-Popper phase LaSrFeO is an example of layer perovskite that finds its application in the rechargeable metal-air battery.

"With ample supply of oxygen from the atmosphere, metal-air batteries have drastically higher theoretical energy density than either traditional aqueous batteries or lithium-ion batteries," he said.

Electrocatalysts for oxygen reduction are critical components that may dramatically enhance the performance of fuel cells and metal-air batteries, which are perceived to be the power for future electric vehicles.

In the metal-air battery, OER is a process of charging reaction at the air electrode, while ORR is a process of discharging reaction.

Six grants went to energy storage technologies, including an ultracapacitor, improved lithium-ion batteries, metal-air batteries that use ionic liquids, liquid sodium batteries, and liquid metal batteries.

Fluidic Energy is a for-profit corporation based in Scottsdale, Arizona that focuses on the development of energy storage solutions, based on its proprietary metal-air battery technology and integrated intelligence.

Zinc-air batteries (non-rechargeable; IEC codes: A, P), and zinc-air fuel cells (mechanically rechargeable) are metal-air batteries powered by oxidizing zinc with oxygen from the air.

A Metal-air battery draws oxygen through a porous ambient "air" electrode (-cathode) and produces water, hydrogen peroxide, or hydroxide anions depending on the nature oxygen reduction catalyst and electrolyte.

The development efforts within this program were focused on the use and development of ionic liquids as the electrolyte in metal-air batteries and to overcome some of the known challenges specific to Zinc-air batteries.

The lithium-air battery, Li-air for short, is a metal-air battery chemistry that uses oxidation of lithium at the anode and reduction of oxygen at the cathode to induce a current flow.

The first ARPA-e grant of $5,133,150 was led by Arizona State University out of the FOA1 program and was focused on ionic-liquid-based metal-air batteries (MAIL batteries).

At a high level, the potential advantages of rechargeable metal-air batteries, and particularly zinc-air batteries, are associated directly with the use of diatomic oxygen from the atmosphere as the source of oxidant in the battery.

There are many potential cost, energy density and sustainability advantages of metal-air batteries in general, and the development of a practical and high-cycle life zinc-air battery has long been considered a significant opportunity in the energy storage space.

At the same time the absence of solid oxidant at the cathode, the use of low cost and abundant metals, such as zinc, at the anode and the absence of hermetic packaging means that fundamentally the cost of metal-air batteries can be very low.

The UNIST research team led by Prof. Jaephil Cho, dean of the Interdisciplinary School of Green Energy of UNIST, demonstrated a new strategy to rationally design inexpensive and durable electrochemical oxygen reduction catalysts for metal-air batteries and fuel cells.
