Electrodeposited three dimensional Pb nano wire Anode for thin film Li-Ion micro batteries
sputtering, electrodeposition, corrosion, energy storage and conversion, thin films
The Pb wire grown over anodic aluminium oxide template is used as anode for Li ion batteries. Thiswork entails porous template formation through double step electrochemical oxidation method optimized by design of experiment and Tafel polarization. The X-ray diffraction results of different anodized specimens show amorphous alumina layer formation. The pores in alumina matrix and the filamentous outward projection of Pb wires are observed from micrographs. The initial discharge capacity of Pb wire and Pb planar thin film is observed to be around 830 and 618 mAh/g respectively. The 55thcycle capacity of Pb wire is observed to be around 485 mAh/g which is very high when compared to theoretical capacity of graphite anodes.
