Yi Cui (Chinese: 崔屹; pinyin: Cuī Yì; born 1976) is a Chinese-American scientist specializing in the fields of nanotechnology, materials science, sustainable energy, and chemistry.

[13][14] In 2005, he joined the Department of Materials Science and Engineering at Stanford University as an assistant professor and started to pursue energy and environment-related research.

In 2008, his team reported "High-performance lithium battery anodes using silicon nanowires",[16] which triggered global interests in the use of nanotechnology and nanomaterials for energy storage.

[21] His group also covers a diverse array of research topics, such as solar cells,[22] two-dimensional materials,[23] electrocatalysis,[24] textile engineering,[25] water technology,[26] air filtration,[27] soil cleanup,[28] and bio-nano interface.

[38][39] Cui has established close collaboration with a number of Stanford faculty, including Steven Chu, Zhenan Bao, Robert Huggins, William Nix, Shanhui Fan, Wah Chiu, Bianxiao Cui, Harold Y. Hwang, Craig Criddle, Alexandria Boehm, Mark Brongersma, Zhi-Xun Shen, Shoucheng Zhang, Michael Toney, and Hongjie Dai, as well as Gang Chen from MIT.

Over the past decade, the original concept developed by Cui's team has evolved into the first commercially produced lithium-ion battery that employs a 100% silicon nanowire anode with breakthrough performance approaching 500 Wh/kg over hundreds of cycles.

In 2017, Cui founded EEnovate Technology to develop nanotechnology for energy-related and environmental issues, including water purification, grid-scale energy storage, and smart wearable textiles.

[90] EnerVenue aims to bring the metal-hydrogen battery technology that powers the international space station into a clean energy revolution, even under extremely challenging climate conditions.
