Abstract: The need for finding low-cost, earth abundant and alternative battery chemistries has resurrected the development of sodium ion batteries. The development of sodium ion batteries is too strongly dependent on the development of the electrode materials. The lower cost of sodium naturally renders the sodium-ion batteries more suitable for large deployments, for which the electrode materials must possess such desirable attributes as strong safety, high rate performance and long cycle life. The cathode material is usually the limiting factor because of its higher cost, more complex synthesis process and lower specific capacity. Cycle life improvement, which weighs in heavily on the life-cycle cost of the sodium ion batteries, has not received extensive attention. This thesis examines methodologies which can improve the practical use of Na<sub>3</sub>V<sub>2</sub> (PO<sub>4</sub>)<sub>3</sub> used as sodium ion battery cathode material. It also examines other alternative battery technologies based on the alkali-metal ions such as the potassium.
