Control of Surface Chemistry and Electrochemical Performance of Carbon-coated Silicon Anode Using Silane-based Self-Assembly for Rechargeable Lithium Batteries

Li0.95Na0.05Ti2(PO4)3/C nanocomposite was prepared by sol-gel method.The structure and morphology of the samples were characterized by XRD, SEM which showed the particles had typical NASICON structure and diameter range from 400~500nm. The electrochemical performance were tested by cyclic voltammetry and galvanostatic charge–discharge. Results show Li0.95Na0.05Ti2(PO4)3/C nanocomposite exhibitsmuch better electrochemical performance than bare Li0.95Na0.05Ti2(PO4)3.

Nanostructured LiFePO4 is appealing cathode material for rechargeable lithium batteries. Herein, however, we report the intriguing anode properties of carbon coated LiFePO4 nanocrystals. In the potential range of 0–3.0 V, the LiFePO4 nanocrystal electrodes afford high reversible capacity of 373 mAh[Formula: see text]g[Formula: see text] at a current rate of 0.05 A[Formula: see text]g[Formula: see text] and retains 239 mAh[Formula: see text]g[Formula: see text] at a much higher rate of 1.25 A[Formula: see text]g[Formula: see text]. In addition, it is capable of sustaining 1000 cycles at 1.25 A[Formula: see text]g[Formula: see text] without any capacity fading. Such superior properties indicate that nanostructured LiFePO4 could also be promising anode for rechargeable battery applications.
