Lithium intercalation edge effects and doping implications for graphite anodes

Charge–discharge stability of graphite anodes for lithium-ion batteries

A graphite powder disk sandwiched between two nickel screens was used as a lithium-insertion working electrode. Electrochemical impedance spectroscopy (EIS), galvanostatic intermittent titration (GIT) using pulsed microcurrent, and in-situ intrinsic resistance measurements were used for the evaluation of kinetics and intrinsic (i.e. physical) resistance changes during charge–discharge cycling f...

The Role of Carbonate Solvents on Lithium Intercalation into Graphite

Quantifying microstructural dynamics and electrochemical activity of graphite and silicon-graphite lithium ion battery anodes

Despite numerous studies presenting advances in tomographic imaging and analysis of lithium ion batteries, graphite-based anodes have received little attention. Weak X-ray attenuation of graphite and, as a result, poor contrast between graphite and the other carbon-based components in an electrode pore space renders data analysis challenging. Here we demonstrate operando tomography of weakly at...

Intercalation compounds of graphite*

A broad review of recent research work on the preparation and the remarkable properties of intercalation compounds of graphite, covering a wide range of topics from the basic chemistry, physics and materials science to engineering applications.

Nanoporous Ag-CNTs foamed electrode for lithium intercalation

Intercalation of lithium into Ag-CNTs sample is reported here. We have used a nano-porous silver foam as a frame for deposition of the CNTs   inside   the   pores   by   electrophoresis   deposition   (EPD) technique. By using  chronopotentiometry method,  we  have noticed that the Li storage capacity of the prepared Ag-CNTs electrode was improved  noticeably  in  comparison  with  literature. ...
