Title
A Study on electrochemical Behavior of Lithium in NiO Thin Films Prepared by reactive Sputtering
이세희Se Hee Lee, 황규호Kyu Ho Hwang, 주승기Seung Ki Joo
Abstract
Electrochemical insertion and removal of lithium into nickel oxide films prepared by reactive sputtering have been investigated. The chemical diffusion kinetics of lithium in NiO thin films have been evaluated by Cyclic Voltammetry and AC impedance spectroscopy. It has been found that charge transfer density improves as NiO becomes lithiated and enhancement of lithium diffusion coefficient with increase of x in Li_xNiO is mainly responsible for it.
