Sodium-Ion Battery: Can It Compete with Li-Ion?

Abstract

As concerns about the availability of mineral resources for lithium-ion batteries (LIBs) arise and demands for large-scale energy storage systems rapidly increase, non-LIB technologies have been extensively explored as low-cost alternatives. Among the various candidates, sodium-ion batteries (SIBs) have been the most widely studied, as they avoid the use of expensive and less abundant elements such as lithium, cobalt, and nickel while also sharing similar operating principles with LIBs. In this Perspective, we discuss why SIBs hold great promise and can act as competitors to lithium-ion technology. In addition, the remaining challenges and future research directions are highlighted, focusing on cathode developments and the use of SIBs in large-scale applications, including electric vehicles and stationary energy storage.

Elucidating Gas Evolution of Prussian White Cathodes for Sodium‐ion Battery Application: The Effect of Electrolyte and Moisture

“…This is especially relevant when considering overcharge events, both intentional and unintentional, and application in confined and poorly ventilated spaces, as commonly found in stationary energystorage systems located in basements, server rooms, etc. [10,41,46,77] In this work, we elucidate the role of carbonate solvents, conductive salts, and water content on the gas evolution of aqueous processed PW cathodes, investigated via DEMS during cycling and overcharge. By using a Na 1.80 (5) Fe[Fe-(CN) 6 ] • 1.84(3)H 2 O PW CAM with Fe as the only transition metal and studying it in optimized electrodes of high areal loading, [43] any observation can be understood as genuinely deriving from the material properties and not as immediate artifacts, e. g. from the presence of other metals in the previously studied high-entropy materials [48][49][50] or from the use of small-scale material and electrode preparation and handling (more prone to the introduction of impurities).…”

An innovative synthesis of carbon-coated TiO2 nanoparticles as a host for Na+ intercalation in sodium-ion batteries

“…Among the elements used for batteries, lithium, cobalt, nickel, copper and even carbon (graphite) will become critical elements in the medium term (2025–2035). 2 Moreover, lithium exploitation is not environmentally friendly, so it is necessary to develop sustainable alternatives for electrochemical storage technologies. Sodium-ion batteries (SIBs) appear as an interesting solution to free ourselves from the use of some critical elements cited previously.…”

A Comprehensive Review on Strategies for Enhancing the Performance of Polyanionic-Based Sodium-Ion Battery Cathodes

“…The higher thermal stability of the polyanionic compounds, particularly for phosphates due to the P–O bond, are promising for mid-range electric vehicles (EVs) and stationary energy storage. 22 But these compounds lag behind in energy and power density when compared to layered transition metal oxides, and also the polyanionic groups can render the transport of electrons, which results in the poor capacity and performance of the materials. This review systematically deals with different ways of improving the electronic conductivity of the polyanionic materials, which is very essential for its better performance.…”
