Problems solved by technology

[0006] In addition, the smaller electrode spacing can make it easier for the acid in the separator to reach the surface of the plate to participate in the reaction, but it is easy to cause a dendrite short circuit and cause the battery to fail abnormally.

Abstract

The invention discloses a high-magnification lead storage battery for communication. The high-magnification lead storage battery comprises a positive plate, a negative plate and an electrolyte; the lead plaster of the positive plate comprises, by weight, 1000 parts of lead powder, 30-50 parts of red lead, 0.5-1.0 part of silver-plated carbon fiber, 2.0-3.0 parts of expanded graphite, 8-10 parts ofsodium bicarbonate, 1.5-2.0 parts of magnesium silicate, 0.3-0.5 part of bismuth oxide, 1.5-2.0 parts of a Teflon solution, 110-120 parts of sulfuric acid with the density of 1.40 g / ml and 100-110 parts of deionized water; the lead plaster of negative plate comprises, by weight, 1000 parts of the lead powder, 1.0-1.5 parts of silver-plated carbon fiber, 2.5-3.0 parts of acetylene carbon black, 12-15 parts of ultrafine barium sulfate, 2.5-4.0 parts of lignin, 1.0-2.0 parts of humic acid, 2.5-5.0 parts of carbon nanotube slurry, 0.5-1.0 part of polyester fiber, 90-110 parts of sulfuric acid with the density of 1.40 g / ml and 100-110 parts of deionized water; and anhydrous sodium sulfate and stannous sulfate are added into the electrolyte. The cycle life of the lead storage battery is two times or more that of a conventional lead storage battery.

Description

technical field [0001] The invention relates to the field of lead storage batteries, in particular to a high-rate lead storage battery for communication. Background technique [0002] Due to its mature technology, low price, large monomer capacity and high safety, lead-acid batteries are widely used in communication, electric power, UPS power supply and other fields, and are currently the most widely used secondary batteries. [0003] In recent years, with the rapid development of the Internet and e-commerce, the construction of IDC data centers has been greatly accelerated. Due to the large amount of data processing and storage, the backup power supply of the IDC computer room is basically a high-voltage system with a large capacity, which requires the battery to have higher specific energy and specific power, so as to reduce the occupation of the installation site and the load-bearing per unit area of ​​the floor. Its backup power requirements for batteries are upgraded f...
