Conventional Li-ion batteries have made progress for HEV applications. However, durability with the PHEV duty cycle and the technology’s ultimate cost and safety remain challenges. To achieve a very high all-electric drive range, a new battery system with advanced high-capacity cathode materials and stabilized high-capacity anode is needed. We disclose strategies to significantly increase the energy density of lithium batteries through developing high-energy cathode material coupled with high-voltage electrolyte.
Wenjuan Mattis received Ph.D. degree in Material Science and Engineering at The Pennsylvania State University, and started working at The Dow Chemical Company on advanced LIB development for the application in HEV, PHEV, EV and consumer electronics for four years. She led the novel high energy and high powder cathode materials cell development, championed high energy storage anode materials development, and developed advanced electrolytes and electrolyte additives for higher performance of cathode and anode materials and improved thermal stability and high voltage stability. In 2013 Dr. Mattis joined Microvast Inc. As VP Technology, she is leading R&D efforts developing advanced batteries targeting EV, HEV and ESS applications. She also work with multiple businesses and core R&D to maximize the innovation pipeline for Microvast R&D function. Dr. Mattis has published 20 papers in prestigious journals, and has filed 30 international patents in energy materials as the first inventor. She has been invited to give 40 presentations at international conferences. She was recently selected to be the board of director of IMLB (International Meeting on Lithium Batteries).
