Electrochemical Intercalation of Potassium into Graphite

© 2016 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim 8103 wileyonlinelibrary.com High performance cathodes, including metal oxides,[11–14] phosphates,[15–18] hexacyanometalates,[19–21] sulfur,[22,23] metal sulfides,[24,25] and organic materials,[26–28] have been reported, and porous carbonaceous materials and metallic Sb and Sn anodes also show high capacity and long cycling stability.[29–34] In c...

The Role of Carbonate Solvents on Lithium Intercalation into Graphite

Electrochemical impedance study of initial lithium ion intercalation into graphite powders

A Johnson Matthey 287 (JM 287) graphite powder disks sandwiched between two nickel screens was used as working electrodes in 1.0 M lithium hexafluorophosphate in mixed carbonate ester electrolyte. Their intrinsic impedance and lithium intercalation kinetics were determined using several different electrochemical impedance spectroscopy (EIS) protocols. The thermal stability of the electrolyte wa...

In situ Raman study of lithium-ion intercalation into microcrystalline graphite.

The first and second order Raman spectra of graphite during the first lithiation and delithiation have been investigated in a typical lithium-ion battery electrolyte. In situ, real-time Raman measurements under potential control enable the probing of the graphitic negative electrode surface region during ion insertion and extraction. The experimental results reveal the staging formation of a si...
