One dimensional MnO2/titanium nitride nanotube coaxial arrays have been designed for a high performance electrochemical capacitive energy storage system based on the concept of fabricating an efficient, fast charge separation network. This nanostructured composite material was prepared by electrodepositing mesoporous MnO2 into TiN (TiN NTA), which are anodization Ti foil substrate and subsequent nitridation using ammonia annealing. The electrodeposited inside electrically conductive...

Lithium-oxygen batteries with high theoretical energy densities have great potential. Recent studies focused on different cathode architecture design to address poor cycling performance, while the impact of interface stability side has been barely reported. In this study, we introduce CoO mesoporous spheres into cathode, where growth crystalline discharge products (Li2O2) is directly observed surface from aberration-corrected STEM. This based demonstrates more than 300 discharge/charge...
