Description:The ECS Detroit Section invites you to “All Solid-State
Battery – A Status Update” presented by Y. Shirley Meng (University of Chicago)
on September 26 at Mercedes-Benz Research & Development North America, Inc.
Dr. Meng is Professor at the Pritzker School of Molecular Engineering at the
University of Chicago. She serves as the Chief Scientist of the Argonne
Collaborative Center for Energy Storage Science (ACCESS) Argonne National
Laboratory.
Abstract
Compared with their liquid-electrolyte analogues, solid
state electrolytes SSEs have drawn increased attention as they promote battery
safety, exhibit a wide operational temperature window, and improve energy
density by enabling Li metal as anode materials for next-generation lithium ion
batteries. Despite suitable mechanical properties to prevent Li dendrite
penetration, relatively wide electrochemical stability windows, comparable
ionic conductivities, and intrinsic safety, most SSEs are found to be thermodynamically
unstable against Li metal, where SSE decomposition produces a complex
interphase, analogous to the SEI formed in liquid electrolyte systems. An ideal
passivation layer should consist of ionically conductive but electronically
insulating components to prevent the SSE from being further reduced. The past
four decades have witnessed intensive research efforts on the chemistry,
structure, and morphology of the solid electrolyte interphase (SEI) in Li-metal
and Li-ion batteries (LIBs) using liquid or polymer electrolytes, since the SEI
is considered to predominantly influence the performance, safety and cycle life
of batteries. All-solid-state batteries (ASSBs) have been promoted as a highly
promising energy storage technology due to the prospects of improved safety and
a wider operating temperature range compared to their conventional liquid
electrolyte-based counterparts. While solid electrolytes with ionic
conductivities comparable to liquid electrolytes have been discovered,
fabricating solid-state full cells with high areal capacities that can cycle at
reasonable current densities remains a principal challenge. Silicon anode
offers a possibility to overcome the challenges that lithium metal anode faces.
In this talk, we will highlight solutions to these existing challenges and
several directions for future work are proposed.
