Herein, the improvement in performance for sodium ion batteries (NIBs) is discussed from available literature and work conducted in the laboratory setting to demonstrate the ability of sodium to perform in the world of energy storage. The reason that sodium is being explored as an alternative to Lithium in energy storage devices is because of the potential depletion of the lithium in the world causing lithium prices to surge. Researchers show that many Sn, Sb, Ge, and other composites perform well as anode materials within NIBs. The research conducted in the dissertation applies the Forcespinning method to produce fibers for use as anode materials in NIBs. The carbon microfibers (CMFs), prove to show initial preliminary results maintaining a cycling capacity of approximately 90 mAhg–1. Further work is being done to determine the initial optimization of Sb/C composite fibers as anode materials in NIBs. Preliminary results for the Sb/C composite fiber anode already show improved performance when compared to that of the normal carbon fiber anodes.
