Electrode Coatings Can Enhance Battery Performance

Zahra Ahaliabadeh, 33, investigated in her dissertation how different thin films affect the performance of lithium-ion battery electrode materials. She aims to continue working on process optimization, material characterization, and scaling up ALD processes for industrial applications.

What is the most significant finding of your dissertation?

Li-ion batteries are at the forefront of energy storage technology, powering everything from portable electronics to electric vehicles and renewable energy systems. Their high energy density, efficiency, and versatility make them essential for transitioning to a sustainable and low-carbon future. 

However, addressing challenges like volume changes and improving their structural stability is crucial for extending their lifespan and performance. By reducing these issues, my work contributes to making Li-ion batteries more reliable, which is critical for advancing green technologies and reducing the world’s dependence on fossil fuels.

The most significant finding of my dissertation is the discovery of the varying effects that different thin films can have on the performance of Li-ion battery electrode materials. I was working on enhancing these materials, and one of the key issues I addressed is the volume change that occurs during cycling, which is a major challenge for Li-ion batteries.

My research demonstrated that applying a surface coating to the electrode can significantly reduce this volume change and enhance the structural stability of the material, ultimately improving the battery’s overall performance and durability.

How can your findings be applied?

My findings can be applied in the development of more durable and efficient Li-ion batteries by optimizing electrode materials through tailored thin-film coatings. 

The research highlights how specific surface coatings can mitigate the volume changes that occur during battery cycling, which is one of the primary causes of electrode degradation. By enhancing the structural stability of the electrode material, these coatings can extend the lifespan of Li-ion batteries and improve their performance.

A key aspect of this research is the use of thin films made by Atomic Layer Deposition (ALD). This technology allows for the coating of even complex surfaces, such as electrode surfaces, solid-state electrolytes, and separators, in a controlled and precise manner. ALD’s ability to create uniform and conformal coatings on intricate structures makes it an increasingly useful technology in Li-ion battery applications.

These findings are particularly valuable for industries relying on high-performance batteries, such as electric vehicles, renewable energy storage systems, and portable electronics. By implementing these thin-film strategies, batteries can achieve longer lifespans, greater reliability, and enhanced safety, making them more cost-effective and sustainable. 

Furthermore, this approach aligns with global efforts to accelerate the adoption of renewable energy and reduce greenhouse gas emissions by enabling better energy storage solutions.

What did completing your dissertation mean to you?

Completing my dissertation was a significant milestone for me, both professionally and personally. It represented years of dedication, hard work, and perseverance in tackling complex scientific challenges. 

It was an opportunity to contribute to the advancement of Li-ion battery technology, an area of research that holds great potential for addressing global energy and environmental issues.

On a personal level, it helped me grow as a researcher, teaching me the importance of critical thinking, problem-solving, and resilience. The process of designing experiments, analyzing results, and overcoming setbacks was immensely rewarding and strengthened my passion for making meaningful contributions to science.

 Completing this work not only validated my ability to carry out independent research but also reinforced my commitment to addressing real-world challenges through innovative solutions.

What are your next career steps?

My next career steps involve building on my current role as a Process Development Engineer at Beneq, where I work on developing advanced ALD thin films for a variety of applications, including energy technologies and semiconductor devices. In this role, I have gained valuable experience in tailoring ALD processes to meet specific application needs, and I’m passionate about leveraging this expertise to drive innovation in these fields.

Moving forward, I aim to further refine my skills in process optimization, material characterization, and scaling up ALD processes for industrial applications. I am particularly interested in contributing to the development of next-generation technologies in energy storage and semiconductor manufacturing.

My long-term goal is to take on roles where I can lead projects that bridge cutting-edge research with practical applications, helping to push the boundaries of ALD technology and make meaningful contributions to sustainable energy solutions and advanced electronics.

What works best as a counterbalance to your work – how do you clear your mind from research?

As a counterbalance to my work, I find that engaging in physical activities and spending time outdoors helps clear my mind and recharge. Whether it’s going for a run, hiking, or simply taking a walk, being in nature allows me to disconnect from the intensity of research and gain a fresh perspective. 

Additionally, I enjoy hobbies like reading, listening to music, or spending quality time with family and friends, which provides a much-needed mental reset. These activities help me maintain a healthy work-life balance, allowing me to return to my research with renewed focus and creativity.
