Comparing Sodium-ion Battery Electrode Materials in the Scope of Grid-Scale Batteries supporting Renewable Energy Sources and Future Electrification Demands

Abstract

With current emission outputs from electricity generation, multiple stakeholders seek to decarbonize and transform current energy grid technology and energy generators. In support of this transition, this paper analyzes the technological capabilities of current grid-scale level energy storage systems and provides a process of prioritizing electrode material qualities. In specific, this paper explores anode and cathode materials for Sodium-ion batteries utilizing attributes oriented for energy grid usage. This paper proposes the weighted-ranking system considering factors of reversible capacity, energy density, cycling ability, and material abundance. This paper seeks to aid those researching future electrode materials for SIBs in the context of future grid-scale level batteries through contextualizing various electrode materials in comparison. This paper also seeks to provide a valid method of comparing multiple electrode materials to recommend specific research and development areas.
