Embodiment Construction

[0014] The present invention and its effects will be further described below through examples and application comparisons.

[0015] Make a multi-cell battery with lead-antimony alloy as the plate. After charging and discharging, and before installing the safety valve, fill spherical water-filled capsules from the valve openings of each cell. The foreskin of the capsule is made of starch-based polypropylene degradable plastic. Production, the degradation period is selected as one year or three years, and the total water capacity of the capsule is 500mm 3 Left and right, consistent with the nominal capacity of the single-cell battery, the resistivity of the pure water inside is greater than 1 megohm.cm.

[0016] The application comparison is as follows:

[0017] In Africa, a telecommunication signal relay station is equipped with two sets of batteries. One set of batteries contained self-hydrating capsules with a preset degradation period of three years, and the other did not....

Abstract

The invention provides an automatic water supplementing method for valve control lead acid battery, and the battery is composed of one or more unit cell; a pole plate is produced from lead-antimony alloy; the unit cell is installed with water containing capsules which are made of starch-base polypropylene or polylactic acid-base degraded plastic; after cover of the capsule is degraded, automatic water supplement of the battery is realized, thereby the battery has a longer usage life in uncertain scenes, random over charge, or over-discharge, high temperature, wind or light energy storage utilization, abnormal commercial power, equator adjacency and other occasions.

Description

technical field [0001] The invention relates to a method for automatically replenishing water for a valve-controlled lead-acid storage battery, which belongs to the field of lead-acid storage battery production. Background technique [0002] Lead-acid battery occupies a pivotal position in the field of secondary batteries by virtue of its excellent performance-price ratio. In all aqueous solution power supply systems, lead-acid battery has a higher working voltage, better high-current discharge performance and high-low temperature discharge Performance, widely used in backup power supply, energy storage, power energy and other fields. [0003] Now the lead-acid battery technology is very mature, especially the use of valve-regulated lead-acid batteries, which makes people more convenient and simple to use, but in some specific occasions, especially where the battery is required to use a large discharge depth and a high life expectancy, Existing products are always unsatisfa...
