Project Details
Description
progress in storage technologies that effectively address the intermittency of clean energy
sources. Electrochemical energy storage methods based on batteries are appealing because they
are not limited by the Carnot efficiency since batteries are not thermal machines and may store
energy with very high performances. However, current battery technologies still require
fundamental improvements to make them safer, more efficient, cheap, and long-lasting. To meet
these expectations, fundamental understanding of processes taking place within batteries and
foundational materials discovery that account for the needed multifunctional nature of
compounds that are used for their fabrication must take place and novel interfacial diagnostics
methods must be developed to reduce chemical, structural and morphological non-idealities.
Despite decades of research, predicting materials behavior and the details of interfacial reactions
in complex electrochemical environments as in batteries has remained a great challenge.
Modern batteries must meet stringent technological demands imposing that battery materials be
designed to satisfy numerous constraints simultaneously. This leaves little room to the traditional
paradigm of trial-and-errorbased sequential materials optimization and requires novel and
rational methods. This project will develop a detailed understanding of interfacial reactions in
all-solid-state batteries including lithium metal and sulfur batteries strategies to prevent unwanted
reactions between solid electrolytes (SEs) and electrode materials. A guiding principle in this
work will be the detailed understanding of interfacial reaction mechanisms and the identification
of fundamental materials traits that control behavior. These studies will be followed with the
development of a mechanistic understanding of the relationship between the electrolyte and the
anode, the roles of their structure and morphology and their impact on cell stability, with the aim
of developing mitigation strategies. This project will help predict SEs that are more robust and
possess superior transport properties and will serve as the basis for improved models that
account for interfacial interactions. With this research, my group hopes to drive fundamental
discoveries that will illuminate the path towards sustainable and efficient energy storage
