Our Mission

Global climate change is the defining challenge of the 21st century. It is imperative that we continue to improve energy efficiency and ultimately move to a carbon-neutral energy cycle. Our research has two inter-related themes:

1.) To develop low-cost, long-life energy storage systems to enable both a renewable energy-powered electric grid and an electric vehicle-dominated transportation system

2.) To engineer rechargeable batteries as an electrochemical-mechanical energy conversion device, i.e., as a high-energy actuator. These actuators can enable a broad range of applications in energy efficiency technologies and beyond

Our research focuses on designing materials and architectures for electrochemical energy conversion and storage applications.

About Us

Prior to joining the Jacobs School faculty, Professor Ping Liu has been a Program Director at the Advanced Research Projects Agency – Energy (ARPA-E) since 2012, where he initiated and managed research programs in energy storage for electric vehicles and thermal management technologies to improve building energy efficiency. He was the manager of the Energy Technology Department at HRL Laboratories and was a research staff member with the National Renewable Energy Laboratory.

He received his Ph.D. in Chemistry from Fudan University in China. He was a Distinguished Inventor in multiple years at HRL and won an R&D 100 award in 2009 for a battery technology developed at NREL. Liu has published over 70 peer-reviewed papers and has been issued 36 US patents in the broad areas of batteries, fuel cells, sensors and actuators.

Prof. Liu now serves as the director of the Sustainable Power and Energy Center at UCSD.
