Two new fast-charging Li-ion battery papers published

We recently published two papers on fast-charging Li-ion batteries in <15 minutes! The first, published in J. Mater Chem A [link], performs operando video microscopy to study Li plating on the graphite anode surface. We study Li nucleation, growth, re-intercalation, and dead Li formation, identifying electrochemical signatures of plating. In the second, published in Continue Reading »

Two new solid-state battery papers published

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.

ALD Aerogel Paper published in Chemistry of Materials

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 »

Solid-state battery perspective published in Joule

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 »
