TLDR
In this paper, the authors used LaNiO 3 as a possible electrode material to replace the carbon support, which has both high electric conductivity and high oxygen evolution activity for metal air batteries.Abstract:
Carbon supported-electrocatalysts are principally used as catalytic layers for air electrodes of metal air batteries. However, these types of air electrodes are problematic because the carbon support can be oxidized to water soluble organic compounds under anodic polarization for a charge process. In this study, we have investigated to use LaNiO 3 as a possible electrode material to replace the carbon support because LaNiO 3 has both high electric conductivity and high oxygen evolution activity. LaNiO 3 was prepared by a reverse homogeneous precipitation method, and then LaMnO 3 , which is active for oxygen reduction reactions, was successfully loaded onto the LaNiO 3 by using a reverse micelle method. LaNiO 3 had a much higher stability against anodic polarization as compared to carbon support. The LaMnO 3 /LaNiO 3 composite electrode showed excellent bi-functional oxygen reduction/evolution activity in an alkaline solution and this makes it a highly potential candidate for use in rechargeable metal-air batteries.read more
