Enhanced Electrochromic Properties of NiO<i>_x</i> Films Through Magnesium Doping Strategy.

ABSTRACT: In order to improve the electrochromic properties of NiO_x films, Mg ions were introduced into NiO_x films using the sol-gel method and the spin-coating method. The introduction of Mg ions leads to the loose structure of the compact NiO_x film, which can provide more channels for the transport of OH^-. In addition, the introduction of Mg ions increases the oxygen vacancies and oxygen interstitial defects in the NiO_x film, which effectively increases the reactive sites and improves the charge transfer efficiency at the interface between the NiO_x film and the electrolyte. The electrochemical results further show that the film electrode (NiO_x-Mg2) has the largest charge storage c
