What is a sodium-sulfur battery? What are the disadvantages of sodium-sulfur batteries

Sodium-sulfur battery is a secondary battery with metallic sodium as the negative electrode, sulfur as the positive electrode, and ceramic tube as the electrolyte separator. Under a certain degree of work, sodium ions permeate the reversible reaction between the electrolyte membrane and sulfur to form the release and storage of energy. Advantages: 1) High specific energy. Specific energy refers to the effective electric energy per unit mass or unit volume of the battery. It is 4 times that of lithium batteries, 5 times that of nickel batteries, and 10 times that of alumina batteries. 2) High current and high power discharge. 3) No self-discharge phenomenon, high charging and discharging efficiency. 4) Short charging time. 5) Use long life. 6) Small size, compact structure and light weight. 7) No pollution and recyclable. 8) Safe and reliable. In addition, it has the characteristics of pollution-free release, vibration-free, and noise-free. Disadvantages: 1) Part of the cycle cannot be solved; 2) It is dangerous when overcharging; 3) The high temperature 350ºC melts sulfur and sodium, so additional heating equipment is needed to maintain the temperature.
