In this episode, we sit down with Dr. Yuan Gao, a materials scientist and executive whose career spans the foundational days of Li-ion research to the executive suites of global cathode manufacturing. Yuan shares his accidental entry into the battery field during late-night shifts with Jeff Dahn, leading to foundational post-doctoral work on manganese spinel cathodes in the mid-1990s.

We explore his subsequent tenure at FMC Corporation, where he contributed to solving critical impedance and safety issues in LCO and LNO cathodes. He also shares the origin story of stabilized lithium metal powder (SLMP) for anode pre-lithiation. Providing a candid look at the corporate realities of battery R&D, Yuan explains how FMC's pursuit of high-margin chemicals led to the eventual abandonment of its pioneering cathode program and the sale of its patent portfolio to Umicore.

Finally, Dr. Gao reflects on his time as CEO of Pulead Technology in China. He unpacks the specific structural advantages of the Chinese manufacturing ecosystem.

Join us as world-renowned electrochemist Dr. Karim Zaghib shares his incredible journey through the history of lithium-ion batteries. Bridging academia and industry, Dr. Zaghib discusses his early research in Europe in the 80s and his front-row seat to Japan's 1990s battery boom. We also dive into his pivotal work commercializing LFP and LTO technologies at Hydro-Québec alongside legends like Michel Armand and John Goodenough, and his current views on how to shape the future of battery development in North America.

Bill Howard brings more than five decades of hands-on experience to the history of battery development, starting at Gould National Batteries in the 1960s and finishing with Medtronic in the 2010s. Bill walks us through multiple battery chemistries from Leclanché cells, to Li/MnO2 cells, to LTO/LCO Li-ion cells and more. He covers how Medtronic learned to manufacture Li-ion batteries in the USA by licensing technology from E-one Moli in Canada. Bill provides a unique perspective on the performance and safety constraints required for implantable medical devices.
