Computational Modeling of Piezochromism in Molecular Crystals
(American Institute of Physics, 2020-06-15)
Synthesis, properties and reactivity of BCl2 aza-BODIPY complexes and salts of the aza-dipyrrinato scaffold
(Royal Society of Chemistry, 2020-02-25)
The synthesis and characterisation of the BCl2-chelated complexes of both archetypal aza-dipyrrin sub- types are presented. A stepwise halogen exchange, leading to a mixed-halide Cl–B–F intermediate, is implicated in the ...
All-Dry Synthesis of Single Crystal NMC Cathode Materials for Li-Ion Batteries
(The Electrochemical Society, 2020-10-08)
Single crystal (SC) cathode materials with a layered structure are considered to be state-of-the-art for lithium ion batteries. However, their production involves many steps and can produce large amounts of wastewater. ...
Engineered Particle Synthesis by Dry Particle Microgranulation
(Elsevier Inc, 2020-04-14)
Highlights
* A method of making monodisperse engineered ∼10-μm particles is introduced
* Core-shell, spherical, and tetrahedral particles demonstrated at ∼100% yield
* Spherical layered oxides for Li-ion batteries ...
LiF as an Alloy Component or Slurry Additive in Si-Alloy Anodes
(The Electrochemical Society, 2020-12-10)
Electrolyte additives are commonly used to improve electrochemical performance in Li-ion cells. The use of solids as electrolyte additives is far less common. Here, Si40'(FeSi2)(60−x)'(LiF)(x)' (' = volume percent) alloys ...
Polyaniline Electrode Activation in Li Cells
(The Electrochemical Society, 2020-04-17)
Polyaniline (PANi) can be used as an electroactive organic cathode material in Li-cells with multiple redox states. The theoretical specific capacity of the emeraldine base (PEB) is 150 mAh g−1. In this study, we show how ...
Electrochemistry and Thermal Behavior of SiOx Made by Reactive Gas Milling
(The Electrochemical Society, 2020-06-30)
SiOx with various oxygen contents were synthesized from Si powder by a simple room-temperature ball milling method by controlling the air exposure time during milling. The resulting SiOx consists of nano and amorphous Si ...
Synthesis, Lithium Insertion and Thermal Stability of Si–Mo Alloys
(The Electrochemical Society, 2020-10-05)
Li insertion was investigated in SixMo100−x (90 ≥ x ≥ 70, Δx = 10) alloys prepared by mechanical ball milling. X-ray diffraction (XRD) and quantitative phase analysis were used to analyze phase compositions of these Si–Mo ...
