Abstract
The growing demand for renewable energy, like solar and wind, places an increasing need for large-scale energy storage systems. These systems are needed due to the intermittent nature of renewable energy sources. Li-ion batteries (LIB) have been selected to perform this task for its high energy storage. However, Li is relatively rare and has various obstacles to its production. Therefore, a more abundant and less expensive alternative is appealing. Sodium-ion batteries (SIB) has been considered a potential candidate for its abundance, low cost, and sustainability. Unfortunately, there are difficulties to overcome when implementing SIB. Sodium (Na) has a higher mass, larger ionic radius, and lower mobility compared to Lithium (Li). These properties cause a reduction in cycle stability, lower energy output, and increased stress/strain in the electrodes structure's inability to support the difference between the two ions. Therefore, finding a new intercalation host that is capable of supporting the transfer of Na+ becomes paramount. This work explores the formation and use of niobium oxide as an anode material for SIBs. Anodization and temperature conditions were tuned to produce a variety of pore sizes with differing morphologies. Initial results indicate that the amorphous material formed at 30V performed at the highest capacity and is further explored herein.
