We recently published two new papers focused on in situ/operando analysis of solid-state batteries (SSB), led by recent Ph.D. graduate Dr. Andrew Davis. The first, entitled “Operando Analysis of Interphase Dynamics in Anode-Free Solid-State Batteries with Sulfide Electrolytes” studies the evolution of the solid electrolyte/current collector interface during initial charging of an anode-free SSB.

Andrew Davis and Robin Rodríguez both successfully defended their Ph.D. thesis exams in Mechanical Engineering this summer. Congrats to Dr. Davis and Dr. Rodríguez!
Our new paper “Tunable Atomic Layer Deposition into Ultra-High-Aspect-Ratio (>60000:1) Aerogel Monoliths Enabled by Transport Modeling” is published in Chem. Mater. We demonstrate tunable control of the ALD infiltration depth into an aerogel monolith and develop a reaction-diffusion model to accurately describe the coating process. The model allows for co-optimization of the total deposition time Continue Reading »
Our joint Perspective article with the Sakamoto group at UM was recently published in Joule, entitled “Transitioning solid-state batteries from lab to market: Linking electro-chemo-mechanics with practical considerations”. In this perspective, we consulted with three major automotive manufacturers to identify key challenges in commercialization of solid-state batteries for electric vehicles, including manufacturing, cell design, Continue Reading »
Our paper “Operando Analysis of the Molten Li|LLZO Interface: Understanding How the Physical Properties of Li Affect the Critical Current Density” is published in Matter. We show that solid-state batteries (SSBs) using high-temperature (molten) Li metal anodes can withstand extremely high current densities of 530 mA/cm2, which is an order-of-magnitude higher Continue Reading »
Ph.D. student Adrian Sanchez and Neil Dasgupta were awarded the 2021 Mechanical Engineering Robert M. Caddell Memorial Award for Research. This award is granted to a Faculty/Grad Student team that have jointly made significant contributions to research in materials and/or manufacturing.
Our paper “Plasma-Enhanced Atomic Layer Deposition of p-type Copper Oxide Semiconductors with Tunable Phase, Oxidation State, and Morphology” is published in Journal of Physical Chemistry C. We demonstrate a new PE-ALD process for CuOx films using a combination of oxygen and hydrogen plasma. This enables tuning of oxidation state in Cu, which is Continue Reading »
Dr. Manoj Jangjid and Dr. Srinivas Yadavalli join the group as postdocs. Welcome!
Congratulations to our Ph.D. students Clare Lanaghan and Daniel Liao, who were both awarded NSF Graduate Research Fellowships!
Postdoc Eric Kazyak is a recipient of the 2020 Ereztech BridgeForward Award, a a financial award program recognizing gifted graduate students and recent post-doctoral graduates pursuing careers in organometallic chemistry and materials science. Congrats Eric! [link]
