Dr. Zhenpeng Yao is a computational material scientist in the Department of Chemistry and Chemical Biology at Harvard University. Zhenpeng conducts research focusing on a variety of phenomena observed in electrochemistry and searching for materials generally used in, yet not limited to, Li-ion batteries, including materials for anodes, cathodes, solid electrolytes, as well as Organic Metal Frameworks (MOFs). First-principles Density Functional Theory (DFT) Calculations, Monte Carlo Simulations, Non-equilibrium Phase Search Method, Nudged Elastic Band theory, and High-throughput/Machine Learning techniques are common tools used.
Zhenpeng's research interests:
- Simultaneous anionic and cationic redox reactivity for high-energy-density electrodes.
- Equilibrium/Non-equilibrium thermodynamics in the electrochemistry.
- Li-ion kinetics and mass transport in lithium-ion battery and solid-state electrolyte.
- High-throughput DFT and machine learning screening for novel chemistries.
