The sulfur-carbonaceous composite positive electrodes are the widely used positive electrodes in sodium-sulfur batteries. The different carbonaceous matrices have different advantages. The macropores can make sure the excellent contact between electrolytes and active materials. The micropores are easily fixed with active materials.
A sodium–sulfur battery is a secondary battery operating with molten sulfur and molten sodium as rechargeable electrodes and with a solid, sodium ion-conducting oxide (beta alumina β″-Al2O3) as an electrolyte.

The high reactivity of the electrodes in a sodium-sulfur battery can be achieved by operating the battery at temperatures ranging from 300 to 350 °C, where both sodium and sulfur, along with the reaction product polysulfide, exist in the liquid state [37, 38].
Molten sulfur and molten sodium are used as the electrode materials for the sodium-sulfur batteries. This kind of battery operates at higher temperatures ranging from 300°C to 350°C. An internal machine is employed for heating purposes to provide the required active temperatures in the system. The electrodes are separated by a ceramic layer.
In a sodium sulfide battery, molten sulfur is used as the cathode and molten sodium is used as the anode. The electrolyte is a solid ceramic-based electrolyte called sodium alumina. When the battery is discharged each sodium atom gives away one electron forming sodium ions. The electrons take the external circuitry to reach the positive terminal.
A research group led by Associate Professor Atsushi Sakuda, President Masahiro Tatsumisago, and Professor Akitoshi Hayashi, at the Graduate School of Engineering, Osaka Metropolitan University, has successfully developed a new positive electrode, made of Na2FeS2, for all-solid-state sodium batteries.
