Nanocrystalline LCO/LLZO Composite Cathode Films for Solid State Batteries

Advanced Energy Materials, EarlyView.
A single precursor solution is solution‐deposited and calcined at only 750°C to yield a dense, nanograined LiCoO2/LLZO composite cathode, in which both phases crystallize independently with minimal interdiffusion. Assembled into all‐solid‐state Li‐metal batteries, the composite delivers 111.7 mAh g−1 initial discharge capacity and retains 93% after 100

Calendering‐Dependent Electrochemical and Cost‐Energy Tradeoffs in Layered – Olivine Blend Cathodes

Advanced Energy Materials, EarlyView.
Blends comprised of LiNi0.9Mn0.05Co0.05O2 (NMC) and LiMn0.7Fe0.3PO4 (LMFP) are investigated to assess the performance – cost tradeoffs. Their rate‐capability benefit is retained only under uncalendered‐to‐moderately calendered states. Although blends reduce voltage decay and improve energy retention, they do not deliver measureable improvement in ...

Coprecipitation‐Enabled Scalable Synthesis of High‐Energy Density Polyanion‐Integrated Disordered Rocksalt Cathodes for Lithium‐Ion Batteries

Advanced Energy Materials, EarlyView.
A coprecipitation‐enabled solid‐state route enables scalable synthesis of the metastable polyanion‐integrated disordered rocksalt cathode, Li1.67Mn1.5P0.17O4, without mechanochemical phase formation or post‐synthesis pulverization. Coprecipitation establishes local Mn–P–O integration in the precursor, while eutectic LiOH/LiNO3‐assisted lithiation ...

How small changes to methylated piperidinium cations impact the synthesis of zeolite SSZ‐39

AIChE Journal, EarlyView.
Abstract Here we report a synthesis study of SSZ‐39 with four different organic structure directing agents (OSDA). The goal was to determine how subtle changes to the OSDA architecture impact crystallization kinetics, material composition, and other properties.

31P Solid‐State NMR‐Enabled Development of a Pt/Aluminum Tripolyphosphate Catalyst for Selective C─O Bond Hydrogenolysis of Phenols

Angewandte Chemie, EarlyView.
31P solid‐state nuclear magnetic resonance analysis revealed the presence of aluminum tripolyphosphate on the surface of a platinum/aluminum condensed phosphate mixture (ACPM) catalyst. This finding led to the development of a Pt/aluminum tripolyphosphate (Pt/ATPP) catalyst for the selective hydrogenolysis of phenols to arenes.

Machine learning–driven design of catalytic processes for sulfur dioxide oxidation: Lessons from the trenches

AIChE Journal, EarlyView.
Abstract Despite the growing use of ML in chemical engineering, the catalytic conversion of sulfur dioxide (SO2) to sulfur trioxide (SO3) remains underexplored from a data‐driven modeling perspective. This study evaluates an integrated workflow for literature‐derived SO2 oxidation data, combining data curation, preprocessing assessment, machine ...
