A recent study conducted by Edith Cowan University (ECU) has revealed that zinc-air batteries could be the future of powering electric vehicles. The research project focused on testing zinc-air batteries using a combination of more affordable, safer, and sustainably sourced materials, resulting in improved lifespan and performance.
The study found that zinc-air batteries are a superior alternative to lithium, addressing the limitations of previous designs. Traditionally, zinc-air batteries have struggled with low power output and short lifespan due to poor performance of air electrodes. However, ECU’s breakthrough involved using new materials, such as carbon, as well as cheaper iron and cobalt based minerals, to redesign the batteries.
Dr. Azhar, the lead researcher, explained that the new design significantly reduced the internal resistance of the batteries, resulting in higher peak power density and long-term stability. This breakthrough not only revolutionizes the energy storage industry but also contributes to building a sustainable society by reducing reliance on fossil fuels and mitigating environmental impacts.
Additionally, the use of natural resources, such as zinc from Australia and air, enhances the cost-effectiveness and viability of these innovative zinc-air batteries for future applications. Dr. Azhar highlighted that while renewable energy sources like solar, wind, and hydro power are crucial for green energy, they are intermittent and not entirely reliable. With the abundance of zinc in countries like Australia and the availability of air, zinc-air batteries offer a highly viable and reliable energy storage solution. ECU’s redesign of zinc-air batteries aligns with the UN sustainable development goals and targets set by the Paris Agreement. These goals emphasize the importance of sustainable energy resources in combating climate change.
