    Electrochemical energy storage induces headaches in industrialists for the same reason it provides such fertile ground for academics: a working, rechargeable battery represents a tight coupling of multiphase phenomena across mechanical, thermal and electrical domains. The properties of battery materials have been well classified in the literature in an anatomical fashion, but systematic treatments of the composite battery electrode and complete storage device have been less rigorous. By treating every cycle of the battery in the materials science framework of process-performance-properties, we are exploiting the very problems that limit low cost materials to primary batteries. By linking sub micron phenomena to systematic consequences through in situ measurements, we are able to demonstrate packaging and cycling methodologies which may lead to low cost, high cycle life grid scale batteries. Bio: Dan Steingart is an assistant professor in Mechanical and Aerospace Engineering and the Andlinger Center for Energy and the Environment at Princeton University. Prior to Princeton he was an assistant professor in the Department of Chemical Engineering at the City College of New York. He has created developed printing process for electrochemical energy storage, distributed sensors for large scale electrochemical processes, and power conversion circuitry for wireless sensor nodes in both academic and industrial laboratories. As a co-founder of Wireless Industrial Technologies (WIT) he was the recipient of a National Science Foundation (NSF) SBIR. WIT generated three contracts from the research and development funded by the NSF. As a graduate student at UC Berkeley he was an Intel Scholar, and received a NSF EAPSI grant to study inkjet printing in Japan, the Daniel Cubicciotti Award from the Electrochemical Society, and a design award from the International Solid States Circuits Conference.
