| Summary: | Research related to Magnesium-Ion Batteries for application in energy storage devices focusing on developing all solid-state batteries becomes subject of interest in achieving a safe and environmentally energy storage device. However, Magnesium-Ion Batteries are facing lower ionic conductivity compared to Lithium-ion Batteries. Hence, this research is presented to investigate the effects of Al3+ substitution on the structural, electrical and electrochemical properties of the Mgo.sTi2(P04)3 compound in enhancing the conductivity of the compound. Herein, NASICON-based framework structure, Mgo.5Ti2(P04)3 was developed as a potential material electrolyte focusing on the solid electrolytes. This research is divided into two (2) parts. The first part is to study the effects of heat treatment at different sintering temperatures (650, 700, 750, 800, 850, 900 and 950 °C) on the parent compound Mgo.sTi2(P04)3 while the second part is to study the effects of trivalent ion, Al3+ at different composition (x = 0.1, 0.3, 0.5, 0.7 and 0.9) in Mgo.5+o.5xAlxTi2-x(P04)3 compound. The sample of Mgo.sTi2(P04)3 parent compound was successfully synthesized via sol-gel method at different sintering temperatures with the same sintering duration (24 hours). Then, the structural, electrical and electrochemical properties of the compound were determined. |
