Two main aspects of electrochemical performance that must be improved in Al-ion batteries are cycle life and discharge rate. One recently proposed advancement to improve cyclability is a molten aluminum chloride-urea graphite battery. This battery improves the mechanism of aluminum ions migrating between their anode and cathode during the charging and discharging phases, using a unique electrolyte made of molten AlCl3/urea. When charging, the anode, made of aluminum, undergoes oxidation to release trivalent aluminum ions (Al 3+ ). As these ions traverse the electrolyte to the graphite cathode, they combine with chloride ions to form AlCl4 - ions. These ions then insert themselves between the graphite layers of the cathode. During discharge, the AlCl4 -ions exit the graphite layers and as they approach the aluminum anode, release an aluminum ion. This ion then assimilates three electrons, reverting to its original metallic form. The performance improvement is achieved with a specific AlCl3 to urea ratio of 1.5 in the electrolyte and at an operational temperature of approximately 120°C, allowing the cationic species [AlCl2(urea) + to move with fewer losses. However, high temperature batteries pose management challenges as they may require an external power supply, which could be a potential drawback of this advancement. These conditions not only ensure efficient ionic movement but also stave off undesired side reactions. While this elevated temperature might raise concerns about the safety of battery operation, it is essential to note that the effectiveness of the battery system relies on these conditions, and it is crucial to implement appropriate safety measures and thermal management strategies. The battery touts a high specific capacity, demonstrating that it can store substantial energy relative to its weight. This, combined with its exceptional rate capability and longevity (with notable capacity retention even after 500 cycles), renders it a promising candidate for large-scale energy storage, especially when juxtaposed against traditional Al-ion batteries with pricier electrolytes .
