The global electric vehicle (EV) market is projected to surpass $1 trillion. Lithium-ion batteries, the backbone of this transformation, face persistent challenges, such as safety risks, performance inefficiencies, and limited predictive accuracy under extreme conditions.
Addressing these issues is critical for the widespread adoption of EVs and renewable energy systems.
At the forefront of solving this global challenge is Emmanuel Olugbade, a Nigerian PhD candidate at Missouri University of Science and Technology in the United States.
Together with Dr. Jonghyun Park, Olugbade has developed a groundbreaking hybrid battery model that enhances predictive accuracy while remaining computationally efficient.
This work, published as an Editor’s Choice in Applied Physics Letters, offers a transformative approach to battery management systems.
“Traditional battery models often fall short when tasked with predicting performance under demanding scenarios.
“We enhanced the widely used single-particle model by integrating Extreme Gradient Boosting, a machine learning technique. This allows the model to deliver real-time predictions with greater accuracy, making it a practical solution for modern energy applications”, Olugbade said.
Olugbade’s hybrid model was rigorously tested under dynamic stress and constant discharge scenarios, mimicking the harshest real-world conditions.
The results showed that it significantly outperformed traditional models, capturing the complex behaviors of electrolytes within batteries.
This innovation holds immense potential for industries like EV manufacturing and grid-scale energy storage, where performance and safety are critical.
As a Nigerian researcher contributing to cutting-edge technology, Olugbade’s work underscores the global potential of local talent.
Better battery management systems mean safer, longer-lasting EVs and more reliable renewable energy grids, directly addressing the needs of Nigeria and other developing nations striving for energy security.
“This research not only demonstrates the immense possibilities of advanced science but also showcases the role of Nigerian scholars in addressing critical global challenges,” Olugbade added.
The implications of this breakthrough are vast, from improving battery performance to enhancing the safety and reliability of renewable energy systems.
With the global shift toward sustainability, innovations like these are essential for meeting rising energy demands.
As Olugbade continues his doctoral journey at Missouri University of Science and Technology, his research serves as an inspiring example of how talent and innovation can drive progress toward a sustainable future.
