Effects of Cold-Rolled Deformation on the Electrochemical Performance of Al Anode Materials

Article Preview

Abstract:

The influence of cold rolled deformation on the electrochemical properties of Al anode materials in 4 mol L-1 KOH solutions was investigated by electrochemical tests and metallographic observation. The results indicate that cold rolled process could improve the electrochemical performance of Al anode alloys compared with that of as-cast alloy. With the increase of deformation, the self-corrosion rate and hydrogen evolution rate of Al anode decreased firstly and then increased slightly. The alloy with 80% cold rolling reduction had the lower self-corrosion and hydrogen evolution rate, longer discharge time and good electrochemical performance.
