Abstract

The electrochemical properties and cyclic performances of commercial LiFePO4 cathode material with different ratio of carbon black (CB) and carbon nanotubes (CNTs) as conductive material were tested in this study. Compared with other samples, the sample with 3 wt % CNTs exhibited the best electro-chemical and cyclic performances at various discharging rate at room temperature; and adhesion strength of electrode was improved by adding CNTs. The enhanced electrode performance may due to the unique natures of CNTs and the contact area of CNTs with active material or current collector.
