Abstract
LTO /Si anode material for lithium-ion batteries were successfully synthesized by two-step hydrothermal method and ball milling synthesis , using tetrabutyl titanate, lithium acetate,silicone powder. In this work, LTO/Si composites with different weight ratios (50%,70%) were prepared and tested as anodes of Li-Ion Batteries.The electrochemical properties of the electrodes were investigated using by cyclic voltammetry , charge-discharge galvanostatic and impedance spectroscopy .Both the anodic and cathodic peaks from LTO and silicon were seen in the composites.LTO/SI Composites with higher Si contents (LTO =30 %et Si = 70%) have higher specific capacity .the results confirme that This material can be used as a high-power anode material in lithium-ion batteries.
