Polymer researcher leading the charge to improve battery life

Dr. Yu Zhu an assistant professor of polymer science at The University of Akron is heading a project to extend the amount of time between battery charges, which will result in an overall improved battery life.

Funded in part by a unique statewide initiative – the Ohio Federal Research Network (OFRN) – Zhu’s team is working to develop advanced materials that will improve a battery’s cyclability (the number of times a battery can be recharged) and increase battery storage density (the length of time a battery can go before needing to be charged). Expanding the time between charges also improves a battery’s overall life.

This project, developed over the past four years through funding from the Department of Energy and a $649,000 grant from the OFRN, has developed a new polymer binding material coupled with a new process that mitigates the issues related to the continuous expansion and contraction of silicone electrodes during the charging and discharging cycles needed to reliably power electric technology.

Any application powered through electric batteries – whether phones, cars, or computers – stands to benefit greatly from the technology. The project is now in the prototype phase and may be able to enter the market within a couple years. This research has garnered excitement in government circles, especially from NASA and the U.S. Air Force Research Laboratory.

“Here in northeast Ohio we do a great deal of work with traditional automotive components,” says Zhu. “But with this development and a better electric vehicle power source, we can expand our manufacturing portfolio, which is really good for our region and for Ohio.”

Dr. Eric J. Amis, dean of the College of Polymer Science and Polymer Engineering, adds, “This type of aligned research network has been tried in other states; however, our approach in Ohio is unique and it’s working well at The University of Akron and throughout the state. Now, with the continued leadership and support from the Ohio legislature, we are able to continue to leverage our OFRN investment and achieve even greater results for Ohio.”
