The evolution of LIBs from applications in small implantable electronic devices to large electric vehicles has proven their success in the consumer market, and their prospects have fueled the development of multiple gigafactories across Europe and Asia. The lithium-ion battery (LIB) market has become one of the hottest topics of the decade due to the surge in demand for energy storage. In addition, SIBs also boast faster charge rates, longer cycle life, and improved safety.

Most companies working on commercializing SIBs are using hard carbon as the anode and Prussian blue analogues or polyanionic materials as the cathode, but prices have yet to reach parity with LIBs.While the production of lithium-ion batteries (LIBs) will be subject to supply chain issues with regard to lithium, nickel, and cobalt, sodium-ion batteries (SIBs) have the potential to provide energy storage at scale using relatively abundant and inexpensive materials.
