Lithium ion batteries are some of the most financially feasible batteries on the market, with respect to their high charge and discharge capacities. However, studies have shown that improvements can be made regarding the reversibility of lithiation and electrochemical capacity of these batteries.

Studies investigating the optimization of lithium ion batteries with the addition of niobium have demonstrated positive impact on charge density and capacity fade, making it a promising anode material for lithium ion batteries. Similar positive impacts have been noted in investigations of reducing particle size to the nanoscale and of including conductive material such as graphite to lithium ion batteries. This study will investigate how these factors impact the structure and electrochemical functioning when combined in a lithium ion coin cell.
