Batteries are critical to contemporary society for portable electronic devices, electrified vehicles and enabling the adoption of inherently intermittent renewable energy such as wind and solar. They are complex systems based on heterogeneous structures that operate far from equilibrium. Pursuit of fundamental understanding over multiple length scales remains critically important to effectively design materials and electrode architectures to ensure that the functional properties of the energy storage systems meet the needs of current and future applications. The active materials and their structures determine the open circuit potential of a battery, however, kinetic factors involving ion and electron transport as well as electron transfer determine the practical utilization of the contained energy. Impediments to ion and electron transport manifest as localized resistances influencing the polarization of the battery while under load. The resistances can originate from numerous sources including particle size and morphology, electrode design, and multiple interfaces. Methods to probe the influence of particle and aggregate size on realizable electrochemistry will be highlighted. Further, the role and control of dynamic interphases will be discussed. Insights into reaction mechanisms and their associated transport processes gained through the use of operando and in-situ methods will be featured.
Dr. Esther S. Takeuchi is a SUNY Distinguished Professor and the William and Jane Knapp Chair in Energy and the Environment at Stony Brook University. She holds a joint appointment at Brookhaven National Laboratory as Chief Scientist and Chair of the Interdisciplinary Science Department. Previously, she was employed at Greatbatch, Inc., where her achievements in lithium batteries led to several technological innovations. Her work was instrumental in the development of the lithium/silver vanadium oxide battery, the power source of life-saving implantable cardiac defibrillators.
