The Electrochemical Energy Technology Lab (EETL) is part of the College of Engineering at Peking University. 

In our group, we are interested in solving the most urgent and tough energy problems in front of us, and we tackle the problems from the perspective of electrochemistry.  

Prof. Quanquan Pang (庞全全)

We aim to develop efficient, reliable and yet low-cost batteries, geared towards grid energy storage and electric transportation, both of which are critical sectors for a clean and renewable future. We also aim to extend our expertise to develop electrochemical solutions for solving the pressing questions pertaining to fossil fuel shortage, CO2 accumulation, innovation on resources recycling and exploitation. 

One thrust of our research is to develop new chemical systems and materials/chemical solutions (electrolytes, electrodes) towards our envisioned systems and applications, and the other is to understand the chemical/materials origin and mechanism of how it works or fails, by applying a range of characterization techniques developed by us and the field.

Prof. quanquan pang (庞全全)

I am a tenure-track assistant professor at Peking University (College of Engineering). I am trained in both materials science and chemistry. I obtained my bachelor degree in materials science and engineering from Huazhong University of Science and Technology, and PhD degree in chemistry from University of Waterloo at 2017. I stayed at Massachusetts Institute of Technology for a postdoctoral training in materials science.

I am extremely interested in understanding and the development of electrochemical processes, as electrochemistry is one of the main principles that connect chemistry and energy. I am interested in any system that relies on the inter-conversion between electricity and chemical energy, and the goal is to understand how to best improve the energy efficiency, energy density, service duration of such system. The ultimate drive is to efficiently utilize renewable energy towards our daily life and create a green industry and environment.
