Electric-field assisted manufacturing of structured electrodes for advanced lithium-ion batteries

Ning Wu

Project Goals and Description:

As the desire for clean energy increases, the lithium-ion battery faces two main challenges: high energy density and fast charging. One promising solution to these two challenges is to make thick and lower tortuosity electrodes, allowing lithium ions to transport more efficiently inside the electrode. Currently, scientists have proposed a few methods, including freeze-tape casting, laser ablation, and magnetic templating. However, they are either difficult to implement on larger scales or costly. Since all kinds of materials, regardless of whether they are conducting or not, are responsive to electric fields, we propose to develop a scalable process that utilizes electric fields to make structured electrodes. Under external electric fields, active materials in the battery can be aligned into linear structures, enhancing the battery performance. More importantly, the electric field can be conveniently combined with the roll-to-roll manufacturing processes. Therefore, developing a system that allows the electric field to assist lithium-ion battery electrode manufacturing is important.

Student Preparation


No specific qualifications are needed. Love to do hands-on experiments is appreciated. Everything can be learned from scratch.




particle synthesis skills physics and chemistry knowledge of nano-scale material science programming skills in numerical calculations software development for quantitative image analysis presentation skills writing skills


The graduate mentor will meet the student formally every two/three days per week to discuss the progress, assign short-term research tasks, and teach specific skills needed. The student will be expected to join the weekly group meeting of our research group. The undergraduate researcher, graduate mentor, and I will meet once a week to discuss the research progress.
