Scientists have understood the areas that need to be improved upon in AIBs. Specifically, scientists have developed the "Molten AlCl3/urea electrolyte" AIB , the "Super long-life CMK-3" AIB , the "High Coulombic Efficiency Aluminum-Graphite" AIB , and the "Graphene film 3H3C Ultrafast Quarter-Million Life cycle" AIB . The following four battery technologies are proprietary AIB systems that each have a unique characteristic that improves performance of general AIBs to match or even outperform current state-of-the-art LIBs as seen in Figure .
