Description
The utility model relates to an electric energy device, especially a sodium-sulfur high-energy battery.
The existing lead-acid storage battery has the advantages of large and heavy volume, low energy, environmental pollution and difficult wide popularization anduse.
The utility model aims at designing a sodium-sulfur high-energy battery with large energy, light weight and small volume, which can be widely used in various vehicles and other fields.
The utility model discloses a realize according to following mode:
the utility model comprises an outer shell, a middle shell and an inner shell which are mutually sleeved, wherein a heat-insulating layer is arranged between the outer shell and the middle shell, and the middle shell is made of refractory earth (such as kaolin)An envelope, the inner shell being a sealed shell made of an ion-conducting ceramic material consisting of Na2O and Al2O3The mixture of the positive and negative copper bars is composed of sodium arranged between a middle shell and an inner shell, sulfur arranged in the inner shell, a positive copper bar extending into the sulfur and having good electrical contact with the sulfur, a negative copper bar extending into the sodium and having good electrical contact with the sodium, and a positive copper bar and a negative copper bar extending out of the outer shell to form a positive electrode and a negative electrode of the battery.
The working principle of the sodium-sulfur high-energy battery is as follows: the sodium and the sulfur work in a molten state, the ion conductive ceramic material forming the inner shell is an electrolyte which can only allow sodium ions to pass through, the ion conductive ceramic material is placed between the positive electrode and the negative electrode to separate the sodium and the sulfur to form an electrochemical loop, and the reaction process is as follows: when initially charged, the sodium atom of the negative electrode easily loses one electron on the outermost layer,form positively charged sodium ions, the sulfur of the positive electrode can easily obtain electrons to become negatively charged sulfur ions, the sodium ions of the negative electrode penetrate through the ion conductive ceramic inner shell to enter the positive electrode and react with the sulfur ions to generate sodium polysulfide Na2S2And the charging process is completed. When discharging, namely, when an external circuit is connected, the sodium at the negative electrode end continuously supplies electrons to the external circuit to enable the sodium ions to become sodium ions, the sodium ions penetrate through the ion conductive ceramic inner shell to enter the positive electrode, and sodium polysulfide Na is continuously generated at the positive electrode2S2. The above charge and discharge process can make the liquid level of the cathode sodium continuously drop, and the anode S and Na2S2The liquid level of (A) is continuously increased, and when charging is carried out again, sodium polysulfide Na of the positive electrode2S2The sodium ions are decomposed into sodium ions and sulfur ions, the sodium ions return to the negative electrode, the sodium ions are also generated at the negative electrode, the sodium ions flow to the positive electrode, the flow directions of the sodium ions and the sodium ions are in dynamic balance finally, the liquid level of the sodium returning to the negative electrode is increased, the liquid level of the sulfur at the positive electrode is reduced, and the liquid level of the sulfur at the positive electrode is restored to the original state finally, so that the battery is a rechargeable storage battery.
The positive effects of the battery are as follows: the portable charger is light in weight, convenient to carry, large in energy, convenient to charge and wide in popularization value.
