Designed for operation in a permanent place or in conditions that exclude the movement of batteries or machines in which they are installed. In most of the batteries produced (types C, SZ, SK and SKE), surface plates serve as positive electrodes, and box-shaped plates serve as negative electrodes. Cases of stationary batteries are made of glass, ebonite and wood (lined with lead from the inside).

The maximum charge current for batteries with N \u1d 9 is 2.5 A. The capacities and charge and discharge currents for batteries with the corresponding N can be found by multiplying the corresponding values ​​\u23b\u29bgiven in Table. 10, on N battery. Self-discharge of batteries is not more than 12% when stored for 1 days. The specific energy of stationary batteries is 4...200 Wh/kg. Warranty period of storage is 1000 year. Warranty period of service XNUMX years, operating time XNUMX...XNUMX cycles.

Stationary batteries with surface plates contain a relatively large proportion of lead in relation to the active mass. Most of them do not have lids, so they require frequent filling with water and a well-ventilated area. These shortcomings are eliminated in stationary batteries with smeared plates of the CH type. These batteries are factory assembled and have caps.

Battery letters:

З closed version
С stationary long discharge
К short discharge
Э ebonite (case material)

On the basis of SN batteries, SNU batteries with a capacity of 80 to 2240 Ah, which have increased mechanical strength, have been created. Stationary also include self-locking lead batteries ABN-72-UHL2 and ABN-80-UHL2 (GOST 21728-76). ABN batteries are used on railways to power automatic blocking devices, signaling, telemechanics and communications in stationary conditions. The letter H means slathered plates. Rated capacity is based on 25-hour discharge mode. Capacity at 12-hour discharge is 85%, at 5-hour discharge - 70% of the nominal. The designation UHL-2 indicates the climatic design and category of placement [5].

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Shrimp will help in the extraction of uranium 06.09.2012

In an attempt to make it easier for the shrimp and crab industry to dispose of the shells, scientists unexpectedly discovered a cheap way to extract uranium from seawater.

As you know, the reserves of uranium ore on Earth may soon run out, which will put an end to obtaining energy using nuclear power plants. However, there is another, practically inexhaustible, billions of tons, source of uranium - ocean water. But since the content of uranium in it does not exceed 3,3 milligrams per ton, its extraction remains unprofitable today.

Chemists have been struggling with this problem for a long time and have made some progress in recent years. The best results were obtained by Japanese researchers at the beginning of the 2003st century. They created a mat of plastic fibers impregnated with molecules that both bound the fibers and absorbed the uranium. In 100, with the help of such a mat, the Japanese "got" a kilogram of uranium out of the water. Such carpets up to 200 meters long can be lowered to a depth of XNUMX meters. They are taken out of the water, washed with an acid solution to release the uranium, and put back into the water.

Various laboratories tried to improve the performance of the "uranium" mat by adding porous "nanoparticles" of silicon oxide or carbon to its composition, but the first serious result was achieved by a team of chemists from the University of Alabama using polymers obtained from shellfish shells.

This group worked under contract with a company that manufactures products from crab and shrimp. The organization was so interested in resolving the issue of shell disposal as soon as possible that it was ready to pay hundreds of thousands of dollars for it. Scientists have developed an appropriate method, having found that the "ionic liquid" - molten salt - is able to extract chitin from the shells. It was also found that chitin is not only the basis of the shells, but is also an ideal means for accumulating uranium, and is very easily and firmly "embedded" in the composition of the fibers of the "uranium" mat.

According to Dr. Robin Rogers, who leads the research team, their mat is capable of collecting twice as much uranium as a Japanese one. This brings it closer to the standards of industrial use, although, says Rogers, their results "are not yet very good for the modern economy." He, nevertheless, is sure that by modernizing the received methodology, his group will be able to find a way out.
