Chemist Research Scientist/Engineer


Wei Tong is a Career-Track Scientist in the Energy Storage and Distributed Resources Division at Lawrence Berkeley National Laboratory. She joined the Lab in April, 2014 and is a member of the Applied Energy Materials Group in the Energy Storage and Distributed Resources Division. She obtained her B.S. and M.S. degree in Materials Science at Wuhan University of Technology, China and her Ph.D. degree in Materials Science and Engineering at Rutgers, The State University of New Jersey in 2010. She specializes in chemical synthesis of solid state materials with emphasis on combinatorial library design and high throughput screening of battery materials.

Her extensive experience and practical knowledge in discovery and development of a variety of battery materials using combinatorial materials approach have led to over 10 inventions in the battery field. Her research interests also extend to the in depth understanding of the electrochemical reaction mechanism within the bulk electrode and at the interface through the advanced characterization techniques.


2021 R&D 100 Award: Layered-Rocksalt Intergrowth Electrode Materials for Next-Generation Li-ion Batteries -  November 29th 2021

A team led by Wei Tong of the Applied Energy Materials Group in the Energy Storage and Distributed Resources Division is one of three Berkeley Lab winners of an R&D 100 Award for 2021.

The team developed a unique layered-rocksalt intergrown cathode material for a new generation of lithium-ion batteries that offers higher capacity, faster charging time, superior cycling, thermal stability, and significantly lower raw material production cost. Layered describes how the atoms are arranged in the crystal structure of the material; specifically, to the layering between the lithium and the transition metal.

The team also included Ning Li, Meiling Sun, Jing Xu, and Wanli Yang of the Advanced Light Source.
