Outline of Final Research Achievements |
New air electrode catalysts composed of a manganese oxide (perovskite La0.6Sr0.4MnO3 (LS0.4M) or MnO2 nanosheet (MnNS)) and nano-carbon materials (Ketjen black (KB), carbon nanotube (CNT) and graphene (GP)) were synthesized, and their oxygen reduction/evolution activities and durability against oxidative corrosion were evaluated for the development of next-generation energy conversion and storage devices such as anion-exchange membrane fuel cells (AEMFC) and Li-air secondary batteries (LABs). As a result, LS0.4M/CNT and MnNS/CNT catalysts using the CNT support with high specific surface area and high graphitization degree were found to exhibit the best balanced performances for both catalytic activity and durability.
