Smart nickel oxide materials for the applications of energy efficiency and storage
MetadataShow full item record
The present dissertation studies nickel oxide-based materials for the application of electrochromic windows and lithium-air batteries. The materials were fabricated via radio frequency magnetron sputtering and subsequently post-treated with thermal evaporation and ozone exposure. The strategies to improve electrochromic performance of nickel oxide materials were investigated including compositional control, morphology tuning, modification of electronic structure and interface engineering ( i.e., Li2 O2, graphene). The electrochemical properties of the resulting materials were characterized in ...
