Biography

Jianhui Wang won the first prize of China High School Chemistry Competition in 2001. He was accepted by Zhejiang University as an exam-exempted student in 2002. He started his researches on the Ni-MH secondary batteries in 2004 and received his bachelor’s degree in 2006. Then he took a joint PhD training among National University of Singapore (2 years), Dalian Institute of Chemical Physics (1 year) and Zhejiang University (2 years), studying on solid-state hydrogen storage materials. After obtaining his PhD degree, he worked in the International Research Center for Hydrogen Energy, Kyushu University as a Postdoctoral Fellow. In August 2013, he joined in University of Tokyo and served successively as a Project Researcher, JSPS Fellow and Chief Researcher, studying on lithium-/sodium-ion batteries and their electrolytes. Since September 2018, he has become the Principle Investigator of Energy Storage & Conversion Laboratory at Westlake University.


Research

Our society is facing increasingly severe pressures from aggressive fossil fuel consumption and environmental pollution. Development of a green and sustainable energy system is an ultimate solution that can alleviate our dependence on the fossil fuel as well as the subsequent environmental pollution caused by the usage of fossil fuel. At Dr. Wang’s lab, we aim to develop highly efficient storage technologies for clean energies via an interdisciplinary research programme of electrochemistry, catalysis, physical chemistry and materials engineering.

With research efforts on energy storage in the past 15 years, Dr. Wang accomplished three main work:

1) developing the first-case nontransition metal (potassium) catalyst for hydrogen storage materials and revealing its mechanism (Angewandte Chemie-International Edition 2009, ChemSuschem 2013),

2) developing the first-case “single salt single solvent” high-voltage lithium-ion electrolyte and realizing a 5V-class battery (Nature Communications 2016),

3) developing fire-extinguishing lithium-/sodium-ion electrolytes and realizing safe and long-life batteries (Nature Energy 2018).

 

In the future, we will go on designing and developing next-generation energy storage technologies, including of various rechargeable batteries and new approaches to hydrogen storage.
