Electrochemical Intercalation of Lithium into Graphite

摘要: The results of a study the electrochemical intercalation lithium into Lonza KS15 artificial graphite in 1M LiClO 4 PC/EC (50:50) electrolyte are presented here. Electrolyte decomposition reactions occur during first discharge at about 0,8 V vs. Li metal and their extent is greatly reduced by addition crown ethers with 12 being most effective. A mechanism proposed for which includes least two types process, namely, propylene ethylene evolution formation on surface solid interphase film alkyl carbonates. stoichiometry found to be inversely dependent cycling rates electrode thickness proportional amount carbon black added
