Generated power decay in liquid-phase batteries makes it challenging to operate appliances from portable electronic gadgets to light vehicles. When strong acids or bases are used as electrolytes, they often corrode and oxidize electrodes, which eventually degrades performance. To address this urgency, we have employed reduced graphene oxide (RGO) obtained by modified Hummer's method followed by microwave exposure; as a laminate for copper (Cu) as well as aluminum (Al) electrodes and have demonstrated that it not only safeguards electrodes against strong acids (e.g., FeCl3)/bases (e.g. NaOH), it also enhances performances manifold. Diverse microscopic and spectroscopic tools have been employed to establish the proof of the concept. The functioning of LED light and potable fan blades has been demonstrated. With RGO electrode lamination, Al/Cu liquid phase batteries, having FeCl3/NaOH as electrolytes; could run for 2 h. Present research would inspire future efforts in renewable energy generation, it is believed.
