Research and development of molten sodium batteries began with the sodium -sulfur (NaS) battery in the late 1960s, followed in the 1970s by the sodium-metal halide battery (most commonly sodium-nickel chloride), also known as the ZEBRA battery (Zeolite Battery Research Africa Project or more recently, Zero Emission Battery Research Activities).
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.
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.
In sodium-sulfur batteries, the electrolyte is in solid state but both electrodes are in molten states—i.e., molten sodium and molten sulfur as electrodes.
This chapter discusses two types of molten salt batteries, the sodium-sulfur (Na-S) battery and sodium-metal halide (ZEBRA) batteries. Both types are based on a β-alumina solid electrolyte and a molten sodium anode. This chapter first reviews the basic electrochemistry and materials for various battery components.
