Dr. Jianlin Li (\u674e\u5065\u6797) is the Energy Storage and Conversion department manager in the Applied Materials division. He leads a department devoted to creating a go-to department that sustains national leadership in advanced materials manufacturing and process scale up for energy storage and conversion applications. The department aims to be a one-stop shop covering from precursors for material development to manufacturing of final devices.<\/p>\n

Jianlin\u2019s research area includes materials synthesis, processing and characterization, electrode engineering, cell manufacturing and prototyping for energy storage and conversion.<\/p>\n

He received bachelor\u2019s degrees in Materials Chemistry and Electronic Information Engineering and a master\u2019s degree in Materials Science from the University of Science and Technology of China. Jianlin received his doctorate in Materials Science and Engineering from the University of Florida, and was most recently a senior R&D staff member and leader of the Energy Storage and Conversion Manufacturing Group at Oak Ridge National Laboratory (ORNL). Prior to joining Argonne National Laboratory, he spent almost 14 years at ORNL where he was the leader of the Energy Storage and Conversion Manufacturing Group. He was among a small team to establish the Battery Manufacturing Facility (BMF) at ORNL in 2012.<\/p>\n

Jianlin is also the recipient of several prestigious awards, including the 2023 UT-Battelle Outstanding Research Output team award, 2021 UT-Battelle Research Accomplishment individual award, three R&D 100 awards and two Federal Laboratory Consortium awards. He holds more than 35 patents and patent applications with 7 licensed, has authored more than 170 refereed journal articles and 11 book chapters and edited one book. Jianlin serves as an associate editor for Journal of Energy Storage and IEEE IAS Transportation Systems Committee.<\/p>\n
