New Paper in Advanced Materials Interfaces

Our paper “Rational Design of Transparent Nanowire Architectures with Tunable Geometries for Preventing Marine Fouling” is published in Advanced Materials Interfaces. By tuning nanowire length, spacing, and branching, we systematically study the impact of surface architectures on wettability, algae fouling, and optical transparency.  Superhydrophobic nanowire arrays completely block marine biofouling for 22 days.

New article in Journal of Power Sources Special Issue

Our paper “Efficient Fast-Charging of Lithium-ion Batteries Enabled by Laser-Patterned Three-Dimensional Graphite Anode Architectures” is published in Journal of Power Sources as a part of the Special Issue celebrating the 2019 Nobel Prize in Chemistry for Li-ion Batteries. We demonstrate 4-6C fast charging in >2Ah pouch cells, with ~90% capacity retention after >500 cycles, which Continue Reading »

New Article in JMCA

Our paper “Electro-Chemo-Mechanical Evolution of Sulfide Solid Electrolyte/Li Metal Interfaces: Operando Analysis and ALD Interlayer Effects” is published in Journal of Materials Chemistry A. We utilize a multi-modal suite of operando methods to study effects of artifical SEI layers deposited by ALD on LGPS solid electrolytes. The study highlights the critical role of mechanical Continue Reading »

New paper published in Matter

Our new paper “Li Penetration in Ceramic Solid Electrolytes: Operando Microscopy Analysis of Morphology, Propagation, and Reversibility” is published in Matter.  We demonstrate 1) Multiple morphologies of Li penetration are observed; 2) The Li within these structures can be reversibly cycled; 3) The most common Li filaments propagate by a mechanical crack-opening mechanism; 4) The dynamic evolution Continue Reading »

New article in ACS Energy Letters

Our paper “Plan-View Operando Video Microscopy of Li metal Anodes: Identifying the Coupled Relationships among Nucleation, Morphology, and Reversibility” is published in ACS Energy Letters. The results provide mechanistic insight into the influence of surface spatial heterogeneity on nucleation and growth behavior and suggest that dead Li formation is influenced more by nucleation than by Continue Reading »

New perspective article in ACS Energy Letters

Our joint perspective article entitled “Challenges in Lithium Metal Anodes for Solid-State Batteries” is published in ACS Energy Letters.  In this collaborative article, we describe recent progress in Li metal-solid electrolyte interfaces, and highlight challenges ranging from an improved understanding of filament growth, chemo-mechanical evolution of interfaces, and operando analysis at a range of Continue Reading »
