Study on the Interface and Performance of Ti-Al Laminated Composite Electrode Materials

The Ti-Al laminated composite materials had been prepared by hot press diffusion bonding in this article, then, treated for different thickness of Al layer in the same process conditions. The change of composite material structure is influences on the performance of Ti-Al were investigated by SEM, HRTEM, electrochemical workstation and so on. The results show that it has the characteristics of the composite's interface and the completion of "metallurgy like" integration between Ti and Al, the chang of matrix structure design of traditional Ti electrode is good for enhance the electrochemical performance of electrode, it is completely changed how the current transfer on the Ti-Al laminated composite materials, so that current distribution of electrode is uniform.
