Abstract
As consistent with various embodiments, an electronic device includes a carbon nanotube film having a plurality of carbon nanotubes. In certain embodiments, a coating, such as an inorganic coating, is formed on a surface of carbon nanotube. The nanotube film supports the device and facilitates electrical conduction therein. The coated nanotube is amenable to implementation with devices such as thin film batteries, a battery separator, thin film solar cells and high-energy Lithium ion batteries.
