Sodium-ion Battery Testing

Sodium-ion batteries (SIBs) have emerged on the global market and are poised to complement the ubiquitous li-ion battery (LIB). SIBs deliver a lower energy density than LIBs but utilize more globally abundant materials and boasts a higher degree of safety. The cell safety comes from less reactive cathode materials, lower cell energy density, and, in some cases, less flammable electrolytes. SIBs function much like the LIBs but with larger alkali ions. The larger alkali ion prevents the use of conventional graphite anodes, commonly replaced with hard carbon. Other material compatibility differences result in a wide range of active and passive materials present in SIBs. The wide range of material components make safety risk assessment difficult. Herein the authors utilize accelerating rate calorimetry and electrochemical analysis to characterize cell safety under storage and transport conditions. This analysis will compare the properties between sodium and lithium batteries.
