Description
Summary:Lithium iron phosphate (LiFePO4)/multi-walled carbon nanotubes (MWCNT) composite electrodes were prepared via a wet-filtration-zipping technique. Mechanical, thermal and electrical properties of the composite electrodes at various temperatures were studied. The composite electrodes exhibited electrical conductivity in the range of 1.1 × 101–3.56 × 101 S/cm. Further, the thermal conductivity, effusivity and volumetric heat capacity were measured. Cyclic voltammograms confirmed good electrochemical performances and high stability during Li+ ion intercalation/de-intercalation.
