Researchers and Scientists at Edith Cowan University in Australia observed that zinc-air batteries could prove to be a better alternative than lithium-ion batteries in order to power EVs.
Talking about Zinc air batteries comprise a negative electrode that is made of zinc and a positive electrode made of air. The main problem has been limited power output due to the poor performance of air electrodes and their short lifespan.
On the other hand, the researcher enables engineers to come up with the batteries by using a combination of new materials. This comprises carbon, cheaper iron, and cobalt-based minerals.
Zinc-air batteries have a higher energy density with respect to lithium-ion batteries. It indicates that they can store more energy in a minimal space. Thus it makes it more efficient and capable of powering EVs for maximum distances.
Comparatively, they are also less expensive in order to produce than lithium-ion batteries. This makes it more affordable for consumers. Additionally, zinc batteries have a longer lifespan than lithium-ion batteries.
According to the study’s lead author, Dr. Muhammad Rizwan Azhar, said:
Rechargeable zinc-air batteries are becoming more appealing because of their low cost, environmental friendliness, high theoretical energy density, and inherent safety.
With the emergence of next-generation long-range vehicles and electric aircraft in the market, there is an increasing need for safer, more cost-effective, and high-performance battery systems that can surpass the capabilities of lithium-ion batteries.
Although, zinc-air batteries have some challenges that need to be addressed before their major adoption. Another challenge is that the air electrode can degrade over time. This reduces the battery’s performance. Also, the Zinc-air batteries are less efficient at low temperatures.
The study is still in its initial stages but the Edith Cowan University researchers are optimistic about the fact that it could result in the development of commercially viable zinc-air batteries for EVs.
