Abstract
The rapid increase in global energy demand has significantly accelerated research and development in energy storage technologies such as batteries, fuel cells, and capacitors. While lithium-ion batteries (LIBs) are widely utilized in electric vehicles, lithium itself is a relatively scarce and geographically constrained resource. To meet the demands of large-scale applications, including electric grids, electric vehicles, and energy storage systems, and obtain energy storage for renewable energy providers, it is essential to explore alternative battery technologies beyond lithium. Sodium-ion batteries (SIBs) have garnered considerable interest as a viable alternative due to the abundance of sodium, easy access to hard carbon, and its competitive energy density. This research aims to investigate the operational limits of sodium-ion batteries, focusing on parameters such as temperature, voltage, and charge rate. By adapting electrolyte additives traditionally used in LIBs, we identify electrolyte compositions that enhance electrochemical performance at both low and elevated temperatures. Ultrasound imaging examines the effects of these additives on gas formation, wetting, and structural changes during cycling. After establishing initial correlations between temperature, charge rate, and electrolyte composition, further analysis is conducted to understand how modifications to the hard carbon anode by using other carbon-based materials and varying the electrode thickness influence SIB performance.
