“…However, to improve their performance in order to meet future requirements, ranging from portable electronics to hybrid electric vehicles, new materials mostly at the nanoscale is very essential 1,2 . Conventional nanostructured electrode materials usually show low electrical and mechanical contact that impedes electronic and ionic conductions during charge/discharge cycling 3,4,5 . In this regard metal-metal oxide materials can be identified as an important candidate where presence of metal is expected to facilitate better electrical conductivity and hence enhancing the energy density and power density of the electrode material.…”
