I am working with graphene oxide nanocomposite materials , and I planed to use LaMnO3 as nanocompoite (GO/LMO) . my question is.. is it bosible to make graphene oxide / LMO nanocomposite materials,
I do not know, since I never work with composites
I’m working with battery-supercapacitor hybrid device, I know that to obtain better performance charge storage in positive electrode must equal to that stored in negative electrode (Q+ = Q−), my...
