We want to fabricate an electrochemical super-capacitor using MgSO4 as a aqueous electrolyte solution. My electrode material is porous carbon materials. Previous literature shows the use of Na2SO4, Li2SO4, (NH4)2SO4, KCl but not MgSo4 as the electrolyte solution. They have got sufficient energy density and higher specific capacitance. But what about MgSO4? Should we use it or there will arise any complexity? If anyone has any idea or any information about its (MgSO4) use as an electrolyte in electrochemical super-capacitors, please kindly share with me. Your kind suggestions will be highly solicited.
