Yayuan Liu (born 1992) is a Chinese-American materials scientist at the Massachusetts Institute of Technology. Her research considers electrochemistry, nanomaterials, and materials characterisation for the development of next-generation batteries. She was selected as one of the 2019 American Chemical Society Young Investigators and included in the 2021 Forbes 30 Under 30 list of top scientists.
After earning her doctoral degree in 2019 Liu moved to the Massachusetts Institute of Technology, where she works alongside T. Alan Hatton on stimuli-responsive gas membranes.[5] Broadly speaking, her work considers the design of new materials that allow high-capacity energy storage in electrochemistry applications. She has concentrated on lithium electrodes for next-generation batteries, which offer the potential for high specific capacities and low electrochemical potentials. Unfortunately, these electrodes are highly reactive and change volume during cycling. Liu has worked to minimise the change in volume through scaffold compositions, control the reactivity of the electrodes through solid electrolyte interfaces, and incorporate electrolyte additives to control the formation of interfaces.[6]
