Long-life, environmentally friendly, low-cost reliable batteries are today urgently requested to meet some crucial demands of our modern society. The current battery technology containing liquid electrolyte which is hazardous and harmful when leaking make it inappropriate for longer applications in electrochemical devices. Thus, in this study, Methylcellulose (MC) was chosen as host in anionic conducting SPE due to its low cost, renewable resources, biodegradable and environmentally friendly and doped with Potassium Hydroxide (KOH). The study was conducted by using casting method as it is the most appropriate technique due to its simplicity and low cost. Methylcellulose (MC) as the host was doped with different weight percentage (wt%) of Potassium Hydroxide (KOH) to fabricate SPEs. The result shows the adding of KOH onto MC was significantly enhanced the physical properties of SPEs. The loading of 0.8g MC with 50% KOH yield the highest conductivity at 2.5774 x 10-6Sm-1at room temperature. From this study, the finding proved that solid polymer electrolyte (SPE) using Methylcellulose (MC) as a proton receiver and Potassium Hydroxide (KOH), dopant salt and filler is a good alternative to replace the commercial and existing electrolyte battery.
