Rechargeable Zinc-Air Batteries: Rechargeable zinc-air batteries from Edith Cowan University (ECU) researchers are a breakthrough. This makes electric vehicles safer and more efficient than lithium-ion batteries. Their solution overcomes zinc-air batteries’ major drawbackthey couldn’t be charged again.
“We have tested it for 950 hours,” said recognized ECU researcher Dr. Muhammad Rizwan Azhar, co-author of a related EcoMat paper. It can be recharged and drained again.” Azhar thinks the battery will sell well in electric car markets.
The battery core is key to this innovative idea. Nickel, iron, carbon, and some cobalt formed a cathode. This catalyst-like cathode draws oxygen from the air to charge and discharge the battery. The oxygen is released once the energy is consumed. “The cathode material gets oxygen from the air to charge and discharge more easily. Azhar explains, “Once used, it gives up that oxygen.”
Existing zinc-air batteries cannot be charged, unlike the new type. “They’ve been around for years but couldn’t charge,” explains Azhar. They were one-time use.”

The chemical process inside batteries powers them. Rechargeable batteries reverse this. Zinc and oxygen react in zinc-air batteries. Rightly, Azhar argues, the battery “breathes air.” ECU team battery life is outstanding. It has a high peak power and works well for a long time. This makes it efficient and vital for cars needing consistent power.
Azhar explains, “We’ve carefully tested these batteries for 34 years, cell by cell.” “We’re working on bigger cells and battery packs. These will soon be employed in genuine EVs.”
The ECU team feels their battery may be utilized in motorsports immediately. The ECU crew and students built a race car. “We are nearly finished adding our battery to this racing car,” Azhar explains.
Beyond racing, Australia should lead the way in producing rechargeable zinc-air batteries. Azhar feels their study may swiftly become market-ready if the commercial sector and government promote it. “Australia has the largest reserves of zinc, which is the main ingredient in these batteries.” it gives Australia a strategic advantage in this endeavor.
The emergence of refillable zinc-air batteries could revolutionize electric car manufacturing. The ECU team solved the charging issue to provide a green, efficient, powerful lithium-ion battery alternative. Australia might lead the global EV battery industry with its enormous zinc reserves if it takes the appropriate steps.

Can zinc-air batteries be recharged?
Zn-air batteries have a unique feature that allows them to be mechanically recharged by simply replacing their zinc anodes. These anodes make up 39% of the battery’s weight, while the carbon (air) cathodes account for 12% and potassium hydroxide serves as the electrolyte at 28%. The recharging process takes place in a specialized plant where spent anodes are removed from the vehicles and replaced with fresh ones. This innovative technology offers a convenient and efficient way to power vehicles without the need for traditional charging methods.
What are the disadvantages of zinc-air batteries?
These batteries are made up of cost-effective and eco-friendly materials, and can last for years if stored correctly. However, their power output is limited due to the underperformance of air electrodes. Despite this drawback, they remain a viable option for those seeking a sustainable and long-lasting energy solution.
Is zinc-air rechargeable?
Zinc-air batteries and fuel cells are types of metal-air batteries that use oxygen from the air to oxidize zinc. While the non-rechargeable batteries are one-time use, the mechanically rechargeable fuel cells offer a longer lifespan. These batteries are known for their high energy densities and cost-effectiveness in production.
Which is better zinc-air or lithium ion batteries?
Zinc-based batteries are ideal for low-power applications like remote controls or flashlights due to their lower power output compared to lithium-based batteries. While zinc-based batteries are known to have a lower power output, they still provide reliable and efficient performance for these types of devices. So, if you’re looking for a battery that can power your low-power gadgets, zinc-based batteries are a great choice.
