Reaction kinetics model in liquid and solid phases and its parameterization for room temperature sodium–sulfur battery

AIChE Journal, EarlyView.
Abstract A multipore, multiphase, continuum model is assembled for the first time for room temperature sodium–sulfur (RT Na–S) batteries, with Na+ ion transport and redox reactions in the liquid electrolyte phase and semisolid phase of precipitates softened by the electrolyte solvent, as guided by molecular dynamics simulations in this study ...

Challenges and enablers in fluidization technology

AIChE Journal, EarlyView.
Abstract Gas–solid fluidized beds provide excellent heat and mass transfer for high‐throughput operations from coating to catalytic conversion and underpin emerging low‐carbon technologies. Yet industrial reliability, scale‐up, and control lag scientific understanding, particularly as finer, stickier, and more variable feedstocks increasingly challenge

Effect of Antagonistic Binder–Catalyst Interactions on Catalytic Activity in Lithium–Sulfur Batteries

Angewandte Chemie, EarlyView.
The binder is shown to interact antagonistically with the catalyst in a sulfur cathode, impeding Li2Sx adsorption onto catalytic active sites. This hinders electrochemical performance and prevents the effective deployment of catalysts. This study showcases catalyst‐binder compatibility as a key parameter for cathode design in lithium‐sulfur (Li‐S ...

Chemical analysis of charged Li/SO(sub)2 cells [PDF]

The initial focus of the program was to confirm that charging can indeed result in explosions and constitute a significant safety problem. Results of this initial effort clearly demonstrated that cells do indeed explode on charge and that charging does ...

Contra‐Diffusion Engineering of Single‐Atom Catalytic Interlayers Enables Reversible Sulfur Redox Chemistry

Angewandte Chemie International Edition, EarlyView.
A contra‐diffusion strategy is introduced to grow uniformly distributed Co–Nx single‐atom catalysts (CoSAs) within a carbonized aramid nanofiber (CANF) interlayer. The resulting CD‐CANF enables efficient polysulfide regulation, low metal loading, and exceptional long‐term cycling stability in lithium–sulfur batteries. ABSTRACT Achieving durable lithium–

Synthesis and Application of Conductive Pitch‐Based Porous Carbon for Energy Storage Device as a Supercapacitor

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Conductive pitch‐based porous carbon materials were synthesized and systematically investigated as high‐performance electrode materials for supercapacitors. Petroleum‐derived pitch was thermally treated and chemically activated using KOH and NaOH at different pitch: activating agent molar ratio (1:1, 1:2, and 1:4) to optimize the pore ...
