Electrochemical performance of H+ implantation intercalate with LiCo3O4 thin film and its applications

Abstract

The purpose of this research is to explore into the impacts of H+ ion implantation on Al/ LiCo3O4/ITO (MIS) thin films employing the sprayed pyrolysis method. The discharged and recharged specimens were characterized using XRD, EDAX, and SEM techniques. Using LiCo3O4 CV curves in KOH solution at various scan speeds, the electrochemical behavior was investigated. Li+ and H+ ions from a KOH solution underwent a reversible insertion into the diffusion coefficient values of LiCo3O4 particles. Increased protonic conductivity and a higher diffusion coefficient value of 3.55x10−8 cm2/S with a scan rate of 100 mV/S are the results of the intercalation of lithium with the cobalt oxide LiCo3O4 and this implantation affects the possible causes of the observed changes in the properties of lithium cobalt oxides. The spray pyrolysis method's process parameters have a major impact on the H+ implantation film's characteristics. As a result, they have been enhanced to produce high-quality LiCo3O4 films with excellent electrical conductivity and transparency.
