<p>Sodium-sulfur batteries (Na-S) are electrochemical energy storage systems where redox reactions occur between sulfur cathode and sodium anode. They exhibit high theoretical capacity, high energy density and long cycle life. They are portable when compared to lead acid batteries and supply power for a long period. The slow redox kinetics and polysulfide shuttling problems limit the practical applications of metal-sulfur batteries. They are more significant for the development of pilot-scale energy storage systems. Na-S batteries work conventionally at high-temperatures that results in more energy loss. Room temperature Na-S batteries are emerging with high energy density, lower cost and more safety. They also suffer from polysulfide shuttling and dendrite formation that hinder the commercialization of these devices. This review paper discusses the increase in the rate capability and cycle stability of Na-S batteries in response to designing of electrode materials, separators and electrolytes to achieve the industry standards.</p>
