Problems solved by technology
[0003] The positive and negative active materials inside the single sodium-sulfur battery are elemental sulfur and sodium respectively. These elemental substances are very dangerous in the air, especially when the operating temperature of the sodium-sulfur battery is 300°C-350°C. They are all in liquid state, which is very dangerous. The sodium-sulfur battery module composed of a large number of single batteries needs special treatment to ensure its safety. The safety design of many kinds of battery modules can no longer meet the needs of sodium-sulfur batteries. module requirements

Abstract
The invention discloses a sodium-sulfur battery module belonging to the energy storage field. The sodium-sulfur battery module includes a heat preservation box and N monomer sodium-sulfur batteries arranged in the heat preservation box. The heat preservation box comprises a bottom plate, a side wall and a top cover. The edge of the top cover is provided with a clamping groove, by which the top cover is clamped with the top surface of the side wall. The top cover is fixed on the top surface of the side wall. The sodium-sulfur battery module can achieve the technical effects that: on the one hand, rainwater can be prevented from immersing into the heat preservation box of the sodium-sulfur battery module; on the other hand, when spraying leakage occurs in one monomer sodium-sulfur battery in the sodium-sulfur battery module, the leakage substances can be isolated in the heat preservation box of the sodium-sulfur battery module, thus ensuring stable operation of the sodium-sulfur battery module.
Description
technical field [0001] The invention relates to a sodium-sulfur battery module in the field of energy storage. Background technique [0002] Sodium-sulfur battery modules are usually constructed by the following method: multiple single sodium-sulfur batteries are first connected in series to form a battery pack, then multiple battery packs are connected in parallel to form a battery block, and then multiple battery blocks are connected in series to form a sodium-sulfur battery module. Energy storage sodium-sulfur battery modules generally operate in outdoor environments, and natural environments such as rain and earthquakes will have a certain impact on the performance of sodium-sulfur batteries; energy storage sodium-sulfur battery power stations are generally realized by connecting multiple sodium-sulfur battery modules in series and parallel. It belongs to the high energy density gathering area. If an accident occurs in a sodium-sulfur battery module, it will have a high ...
