Abstract

The powders of Li4/3Ti5/3O4/Ag composite were prepared by sol-gel technique. Structural identification, surface morphology and electrochemical properties of the powders were studied by X-ray diffraction, scanning electron microscopy and galvanostatic charge-discharge experiments. The results show that Li4/3Ti5/3O4/Ag composite derived from sol-gel is a composite of Li4/3Ti5/3O4 and silver. Li4/3Ti5/3O4/Ag composite shows higher specific capacity, higher columbic efficiency and lower polarization than Li4/3Ti5/3O4. The addition of silver greatly improves the cycleability of Li4/3Ti5/3O4, especially at higher charge-discharge rate.
