Safety Improvement of Lithium Ion Batteries by Organo-Fluorine Compounds

Journal of Fluorine Chemistry, 2011
Abstract Thermal stability, electrochemical oxidation stability and charge/discharge characteristics of natural graphite powder were investigated by mixing of five fluoro-carbonates with 1 mol/L LiClO 4 –EC/DEC/PC (1:1:1 vol.). DSC study revealed that thermal stability of the electrolyte solution was improved by mixing of fluoro-carbonates by 10.0–33.

Thermal and Oxidation Stability of Organo-Fluorine Compound-Mixed Electrolyte Solutions for Lithium Ion Batteries

Journal of Power Sources, 2013
Abstract Thermal and oxidation stability of fluorine compound-mixed electrolyte solutions have been investigated. Charge/discharge behavior of natural graphite electrode has been also examined in the same electrolyte solutions. Fluorine compounds demonstrate much lower reactivity with metallic Li than ethylene carbonate/dimethyl carbonate.

Effect of Organo-Fluorine Compounds on the Thermal Stability and Electrochemical Properties of Electrolyte Solutions for Lithium Ion Batteries

Journal of Power Sources, 2013
Abstract Thermal stability and electrochemical behavior of fluorine compound-mixed electrolyte solutions have been investigated using 1 molL−1 LiClO4-EC/DEC/PC, 1 molL−1 LiPF6-EC/DMC and 1 molL−1 LiPF6-EC/EMC/PC. DSC study indicates that no exothermic reaction occurs between metallic Li and fluoro-ethers while EC/DMC mixture and fluoro-carbonate ...

Investigation Into Antimony Pentafluoride-Based Catalyst in Preparing Organo-Fluorine Compounds

Journal of Molecular Catalysis A, 2005
Abstract Antimony pentafluoride (SbF 5 )/porous metal fluorides (PMF) were prepared by impregnating PMF with SbCl 5 , and then fluorinating with anhydrous hydrogen fluoride (AHF). It demonstrates excellent activity in vapor-phase catalytic fluorination and overcomes such drawbacks as hygroscopicity, corrosion and toxicity that appear while SbF 5 was

Organo-Fluorine Compounds

Journal of Fluorine Chemistry, 2000
Organo-fluorine compounds have become increasingly important in the last 50 years, as synthetic routes to them have been developed; very few occur naturally. Their chemical behavior covers the entire range from inertness to high reactivity and their physical properties show unique features.

Current approaches to the electrochemical synthesis of organo-fluorine compounds

Journal of Applied Electrochemistry, 2004
Recent trends in the synthesis of organo-fluorine compounds using the conventional selective electrochemical fluorination (SEF) route as well as other novel synthetic approaches are presented. In the conventional SEF route, fluorinations of the active methylene group in the side chain as well as unsaturated alkenes have been achieved.
