Blog Article

This work describes the preparation and the characterization of various samples of metallic Sn electroplated on a cupper foil under different current and time regimes.These samples have been characterized by XRD and SEM and tested as negative electrodes in a cell using lithium foil as the counter electrode.The best electrode has been cycled with a capacity in hus726040als214 the order of 990 mAhg-1, i.

e.approaching 100 % of theoretical capacity at 1 equivalent Li alloying.This electrode was also tested under a limited capacity regime (400 mAhg-1) showing an interesting cycle life.

Finally, the electrode was used as anode in a lithium-ion cell with LiNi0.5Mn1.5O4 as cathode.

This cell performed well at high rate stor trebolle (1C rate), delivering high capacity and excellent charge-discharge efficiency for a limited amount of cycles.
