Advanced Energy Materials, EarlyView.Moisture exposure induces the formation of reductive solid phases on argyrodite Li6PS5Cl, which destabilize Ni‐rich cathodes by extracting lattice oxygen and inducing surface reconstruction. A brief oxygen‐assisted annealing treatment quenches these reductive phases, restores interfacial stability, and enables effective regeneration and reuse of ...

Advanced Energy Materials, EarlyView.Frontier orbital energy engineering of PTFE by incorporating electron‐withdrawing oxygen‐ and nitrogen‐containing functional groups alters the local electronic environment and elevates the LUMO energy. This molecular modification strategy suppresses reduction‐induced side reactions in dry‐processed anodes.

Empirical LCAO parameters for $\pi$ molecular orbitals in planar organic molecules
, 2008 We present a parametrization within a simplified LCAO model (a type of Hueckel model) for the description of $\pi$ molecular orbitals in organic molecules containing $\pi$-bonds between carbon, nitrogen, or oxygen atoms with $sp^2$ hybridization, which ...

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 ...

Developments of catalysts for the direct conversion of aqueous ethanol to butadiene
Green Carbon1,3-Butadiene is an important chemical raw material, especially with its large market demand as the main monomer for rubber tires. It is mainly produced by the thermal cracking of naphtha as a by-product of olefin production. The production process faces

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Polyvinylidene fluoride (PVdF) is commonly used as a binder material in the preparation of anode or cathode electrode slurries for commercial Li‐ion batteries (LIBs). High‐cost PVdF binder generally requires the use of toxic and environmentally unfriendly N‐methyl‐2‐pyrrolidone (NMP) as a solvent for dissolution.
