Effect of nano-segregation phases on electrochemical property of high active Al alloy anode

摘要：

The effect of nano-segregation phases formed during rolling process on the electrochemical property of Al-Mg-Sn-Bi-Ga-In alloy anode in alkaline solution (80℃, Na2SnO3+5mol/L NaOH) was analyzed according to the chronopotentiometry (E-T curves) , hydrogen collection tests and modern microstructure analysis. The results show that when controlling the rolling temperature and pass deformation at 370℃ and 40% respectively, the Al alloy anode undergoes the dynamic recrystallization, which benefits to the uniform distribution of nano-segregation phases and improvement of electrochemical property of Al alloy anode. The optimum Al alloy anode has the more negative electrode potential of about -1.48V (vs.Hg/HgO) and the lower hydrogen evolution rate of 0.1889mL/(min·cm2).
