Carbonous nanocomposites of Mn2Mo3O8/MnO as active materials for studying lithium and hydrogen storage application

Abstract

High conductivity of carbon-based materials makes them capable of offering the ideal conditions for energy storage via electrochemistry. Along with metal oxide complexes, nanoscale carbon materials with active sites can play a function in the lithium or hydrogen storage process. The active materials of Mn2Mo3O8/MnO were synthesized via solvothermal method in the presence of diverse carbonous compounds such as graphene oxide (GO), multiwall carbon nanotubes (MWCNTs) and activated charcoal (AC). The resultant samples analyzed as electrode materials for using in the hydrogen storage and lithium-ion battery. Both electrochemical devices assemble in the specific medium for investigating the capacity and performance in order to energy storage ability. The synthesized sample in the presence of MWCNTs show better results in terms of capacity and cycle life in the lithium-ion battery system and hydrogen storage application. Also, data collected from XRD patterns were used to characterize the microstrain and crystal size for the obtained samples. FE-SEM, HR-TEM, and BET-BJH techniques were used to examine the morphology and porosity of the samples.
