Abstract:
Rechargeable Li-ion batteries have dominated the market for twenty years. However,
the increasing demand for energy storage creates new challenges for further use of lithium-ion batteries
mainly due to the problems associated with lithium sources and safety issues [1]. Na-ion based battery is an
appealing alternative with comparable energy density to Li-ion based technologies [2]. Moreover, the fast
ion intercalation/deintercalation in the aqueous electrolyte media could allow for the operations under high
electric current conditions required especially for high power supply and eliminate safety issue [3].
