Layered Sodium Titanate Nanostructures as a New Electrode for High Energy Density Supercapacitors

Layered Sodium Titanate Nanostructures as a New Electrode for High Energy Density Supercapacitors

A flower-shaped hydrated layered sodium titanate material, Na2Ti2O4(OH)2, have been synthesized through a facile hydrothermal method and subsequently converted into sodium free titania (anatase). Potential application of the Na2Ti2O4(OH)2 as an electrode for supercapacitors under pseudo-capacitance...
