Abstract
Lithium ion batteries (LIBs) currently dominate the battery market due to their high capacity and cycling stability. However, because of lithium’s scarcity, the forthcoming demand for large scale energy storage will need to be satisfied by systems that use more abundant resources. Sodium ion batteries (NIBs) are a suitable alternative, but for NIBs to compete with LIBs their cycle life and capacity need to be improved. One way of improving these characteristics is to alter the electrolyte.
In this study, the effect of the phosphazene additive FM2 was examined by varying the additive percentage in relation to carbonate solvent in a NIB system. The efficiency, lifespan, and specific capacity of cells with the FM2 additive were compared to cells made with the commercially used fluoroethylene carbonate (FEC) additive. The results of this study will add to the ongoing effort to develop more sustainable battery systems.
