Sulfur battery sodium is the United States Ford (Ford) was invented in 1967, the company announced today, only about 40 years. The battery is usually caused by the cathode, anode, electrolyte, membrane and shell, etc. parts. Conventional rechargeable batteries such as lead acid batteries, nickel-cadmium batteries with electrodes and solid electrolyte composed of liquid sulfur Laptop battery sodium is, however, is the electrode of the liquid composition liquid electrolyte and solid, the composition of its negative activity equipment is sodium molten metal, the cathode active material is molten sulfur and sodium polysulfide, because sulfur is an insulator, so sulfur is usually filled with the porous conductive carbon or graphite felt, the solid electrolyte and a conductive membrane is a specialized sodium ions are known as the envelope of Al2O3 ceramic materials are usually stainless steel and other metallic materials.

 

Sulfur battery sodium has many functions: An office of the specific energy (eg, per unit mass or volume of cells have the power valid) high. The theoretical specific energy of 760Wh/Kg actually more 100Wh/Kg is a lead-acid batteries 3-4 times, the other is high current discharge, high power. The current density of discharge is usually up 200-300mA/cm2, and the instantaneous time can be three times the release of its inherent energy, another is the charge-discharge efficiency. Following the solid electrolyte, so there is no liquid electrolyte secondary battery is usually the kind of self-discharge and side effects, charge-discharge current efficiency is practically 100%. Of course, things are always divided into two, sulfur and sodium batteries are also weak, its operating temperature to 300-350 ℃, therefore, the Dell Inspiron B120 battery needs some work, heating insulation. However, high-performance vacuum insulation and thermal insulation technology, which can effectively solve this problem.

 

Power of sodium sulfur batteries as a new family of chemicals, the emergence of a new member, has been in many countries around the world, much attention and development. As the sulfur battery sodium has a range of attractive features of high-energy batteries, so a start on the first of a number of countries are engaged in the development of electric vehicles used as traction batteries, also made very encouraging results, but with the passage of time has shown that sodium sulfur batteries in a mobile situation (eg electric vehicles) to use the conditions are difficult, whether using the space, safety of the battery itself, so there is a certain limit. Therefore, in the late 80s and early 90s, the foreign accent on the development of sulfur battery sodium opportunities as fixed (such as storage of electrical energy) applications, and more to demonstrate its superiority. As Japan and Tokyo Electric Power Company (TEPCO) and NGK companies to develop batteries that sodium sulfur battery energy storage, its demands for electric power upgrade charge (it ie, from Clipping Pinggu role will be night, excess electricity is stored in the hp F4809A battery inside, day with the peak power, then released from the battery), UPS and emergency power compensation of instantaneous power, etc., and in 2002 entered the marketing stage of implementation, has become the largest (8 MW) batteries sodium sulfur storage devices, energy from 2005 years during October statistics, annual production capacity of sodium sulfur battery batteries on 100MW, while beginning to export abroad.

UPS battery used in 3 Note:

Actually available for all discharged UPS battery size and battery current, Laptop battery temperature of the working environment, storage duration and load characteristics are closely linked. If you are not actually the UPS power supply, use often cause the actual available capacity of the batteries is far less than the nominal capacity. To this end, the user should pay attention to the use of batteries, the following points:

 

1. Rechargeable battery end of discharge and open-circuit load, a large number of internally-generated lead acid batteries do, and adsorption on the cathode of the battery with the cathode form the so-called “sulfate”, which rises in the battery internal resistance, battery charge-discharge performance may be affected. Now commonly used in M type sealed lead-acid battery life of about 3 ~ 5 years.

 

2. For most of the UPS power supply in case, the battery after every discharge can be used to float within the charging circuit. To ensure the battery-charge placed in saturated state, usually requiring 10 ~ load time is 12 hours. Charge time is not enough to cause the Dell U4873 battery is charged, is not sufficient, so the actual available capacity of the battery is much smaller than the nominal capacity. Voltage 200V lower than in the city, has some of the UPS power failed to use the internal charging circuit for charging the battery up to saturation.

 

3. To ensure the battery has a good charge and discharge characteristics, long-term idling UPS power supply (UPS start blackout for more than 10 days), before re-use, it is best not to increase the load, so that the use of equipment, UPS power supply battery charging circuit of the float 10 to 12 hours before use. UPS back-up style for the use of the user when the UPS back-up is long-term work in the group, it is recommended at intervals of one month to allow UPS inverter power supply in the state for at least 2 to 3 minutes to To activate the battery.
