What is the use of sodium-sulfur batteries?

Sodium and sulfur will chemically react to store electrical energy. When the grid needs more electrical energy, it will convert chemical energy into electrical energy and release it. The flood storage performance of sodium-sulfur batteries is very excellent, even if the input current suddenly exceeds The rated power is 5-10 times, it can also bear it calmly, and then release it to the power grid with stable power. This is especially useful for the smooth operation of large-scale urban power grids. From the comprehensive consideration of power supply capacity, energy efficiency, installation cost, rated power discharge capacity, installation site requirements, maintenance requirements and other factors, the overall characteristics of sodium-sulfur batteries are most suitable for large-scale energy storage systems. Sodium-sulfur batteries have unique advantages for energy storage, including low raw material and preparation costs, high energy and power density, high efficiency, freedom from site restrictions, and convenient maintenance. Sodium-sulfur batteries have several advantages: one is higher than energy. Its theoretical specific energy is 760Wh/Kg, which is actually greater than 150Wh/Kg, which is 3-4 times that of lead-acid batteries. The other is high current and high power discharge, which can release 3 times the inherent energy instantaneously; the other is high charging and discharging efficiency.
