Problems solved by technology

[0003] The invention solves the single function of the existing elastic bridge used for VRLA batteries due to the material used, that is, it only has the characteristic of being suitable for the elongation of the positive plate, and cannot well prevent the electrolyte from drying up, the thermal runaway of the battery and the elongation of the positive grid To solve the problem of uneven stress on the bottom of the shell when pressure is generated on the bottom of the shell, a new type of elastic bottom pad for VRLA batteries is provided

Embodiment 1

[0016] An elastic bottom pad is used for fixing a valve-regulated lead-acid battery, and the elastic bottom pad 1 is made of elastic glass fiber cotton. A rigid perforated plate 2 is attached to the elastic bottom pad, and the holes on the rigid perforated plate have a spacing of 10 mm and a diameter of 2.4 mm. Put the elastic bottom pad 1 on the bottom of the battery case, cover with the rigid perforated plate 2, and then assemble according to the normal assembly process for fixing the valve-regulated lead-acid battery. In use, since the two poles of the storage battery are very close to the bottom of the housing, the elastic bottom pad and the rigid perforated plate can be prevented from overturning. The elastic bottom pad absorbs and stores a certain amount of electrolyte in advance. After the fixed valve-regulated lead-acid battery has been used for a period of time, the electrolyte decreases and the positive grid elongates. The elastic bottom pad slows down the pressure ...

Embodiment 2

[0018] An elastic bottom pad for fixed valve-regulated lead-acid batteries, the elastic bottom pad is made of acrylic fiber.

Embodiment 3

[0020] Elastic bottom mat for fixed valve-regulated lead-acid batteries, the elastic bottom mat is made of polyester.

Abstract

This invention relates to a spring bearing plate of a fixed valve-controlled lead acid storage battery made of a hydrophilic spring material of H2SO4-proof, which can not only reduce the pressure to the shell generated by extension of the positive pole plate grating but also can supplement electrolyte of the cell to solve the problem of loss control of heat and drying up of electrolyte.

Description

technical field [0001] The invention relates to a fixed valve-regulated lead-acid battery, in particular to an elastic bottom pad for a fixed valve-regulated lead-acid battery. Background technique [0002] At present, fixed valve-regulated lead-acid batteries (referred to as VRLA batteries) are quickly accepted by the market due to their easy maintenance and little environmental pollution during use, and are widely used. However, after a period of use, VRLA batteries will have problems such as thermal runaway, dry electrolyte, and elongation of the positive grid. The elongation of the positive grid will cause the deformation of the electrode group and the positive plate, and generate pressure on the bottom of the case. This pressure will react on the battery cover on the upper part of the case, causing the sealant or bonding between the slot covers to crack, resulting in VRLA The battery life is prematurely terminated. Thermal runaway and dry electrolyte will lead to a de...
