Abstract

The invention provides a valve-controlled sealed lead-acid storage battery capable of meeting the demand of development of a large scale data center at present and satisfying the use of high power discharge with a long floating charge cycle life. In the valve-controlled sealed lead-acid storage battery disclosed by the invention, the longitudinal ribs of the grid mesh thereof are radially distributed, and the tab is in the middle. The interval between the longitudinal ribs is 0.7-0.8 time that of the transverse ribs, and the plate grid is formed by using a high-tin low-calcium alloy with tin content of 1.2-2 w% and calcium content of 0.04-0.05 w%; the apparent density of the positive lead paste formula is 4-4.1 g / cm<3>, the apparent density of the negative lead paste formula is 4.4-4.5 g / cm<3>; the positive plate gamma value is 0.70-0.80, an organic fibrous material is added to the separator, the separator has the base weight of 163-176 g / m<2>.mm at 10kPa, the separator has the porosity of 93-94%; the electrolyte acid density is 1.30-1.31 g / cm<3>.

Description

technical field [0001] The invention belongs to a valve-controlled sealed lead-acid storage battery, and in particular relates to a storage battery used in the field of data centers. Background technique [0002] With the development of e-government and e-commerce, some large-scale government data centers, industry data centers and enterprise data centers have been established. On the other hand, more data centers are under construction and preparations. Therefore, there is an increasing demand for large UPS power supplies, and there are new requirements for the performance of UPS power supplies used in data centers. The new development trend is that valve-regulated sealed lead-acid batteries are still mainly used, but their types are developing from 2V to 6V and 12V. The specific power requirements are getting higher and higher, the reliability requirements are getting higher and higher, and the backup time is getting shorter and shorter. , Internet companies develop from ...
