Nanostructured Lithium-Aluminum Alloy Electrodes for Lithium-Ion Batteries

Electrodeposited aluminum films and template-synthesized aluminum nanorods are examined as negative electrodes for lithium-ion batteries. The lithium-aluminum alloying reaction is observed electrochemically with cyclic voltammetry and galvanostatic cycling in lithium half-cells. The electrodeposition reaction is shown to have high faradaic efficiency, and electrodeposited aluminum films reach t...

Irreversible capacities of graphite anode for lithium-ion batteries

Electrochemical impedance spectroscopy (EIS) and in-situ intrinsic resistance measurements were applied to sandwiched disk graphite electrodes to investigate the mechanism of formation of irreversible capacity during initial galvanostatic or potentiostatic lithium intercalation into graphite in four different electrolyte formulations. The stability of the solid electrolyte interphase (SEI) film...

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...

Kinetic characteristics of mixed conductive electrodes for lithium ion batteries

The rate performances of four mixed conductive electrodes (Li4/3Ti5/3O4, LiFePO4, LiCoO2 and LiCo1/3Ni1/3Mn1/3O2) were investigated using alvanostatic charge/discharge, electrochemical impedance Spectroscopy (EIS) and galvanostatic intermittent titration (GITT). These four electrode aterials can be roughly divided into two groups according to the structure change during Li intercalation/extract...
