Semi-empirical modeling of charge and discharge profiles for a LiCoO2 electrode
نویسندگان
چکیده
The experimental charge and discharge profiles of a LiCoO2 electrode show that the overpotential of the electrode does not change much during alvanostatic charge, but changes significantly during galvanostatic discharge. Semi-empirical porous electrode models are presented to simulate he charge and discharge profiles of the LiCoO2 electrode. The symmetry factor is empirically assumed to decrease with the state of discharge of he electrode to enable the model predictions to agree well with the experimental discharge profiles. 2006 Elsevier B.V.

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. ...

Scanning electron microscopy (SEM) is used to characterize the mi...
متن کاملMoving Boundary Model for the Discharge of a LiCoO2 Electrode
A moving boundary model in a spherical LiCoO2 particle is presented to account for the diffusion controlled phase transition in LiCoO2 solid particles, and this model is incorporated into a porous electrode model for the LiCoO2 electrode. The simulation results agree well with the experimental data of a LiCoO2 electrode. A study of the flux distribution in the porous electrode shows that the ph...

متن کاملKinetic 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...
