The sodium–sulfur battery uses sulfur combined with sodium to reversibly charge and discharge, using sodium ions layered in aluminum oxide within the battery's core. The battery shows potential to store lots of energy in small space.
A sodium–sulfur (NaS) battery is a type of molten-salt battery that uses liquid sodium and liquid sulfur electrodes. This type of battery has a similar energy density to lithium-ion batteries, and is fabricated from inexpensive and low-toxicity materials.
Lifetime is claimed to be 15 year or 4500 cycles and the efficiency is around 85%. Sodium sulfur batteries have one of the fastest response times, with a startup speed of 1 ms. The sodium sulfur battery has a high energy density and long cycle life. There are programmes underway to develop lower temperature sodium sulfur batteries.
Additionally, during the charge/discharge process of Na–S batteries, long-chain polysulfides convert to short-chain polysulfides, with intermediate products dissolving in the electrolyte, causing a loss of active material and rapid capacity decay (Fig. 1 d).
At 350 °C, the specific energy density of the battery reached 760 Wh/kg, which is approximately three times that of a lead-acid battery. As a result, sodium-sulfur batteries require approximately one-third of the area needed for lead-acid batteries in identical commercial applications .
Cheol-Wan Park et al. studied the discharge properties of an all-solid sodium–sulfur battery (ASNSB) using a poly (ethylene oxide) (PEO) electrolyte. The ASNSB using a PEO polymer electrolyte gave a high initial discharge capacity of 505 mA h g −1 sulfur at 90°C with plateau potential regions at 2.28 and 1.73 V.
