Novel lead-acid storage battery clapboard and preparation method thereof

Abstract

The invention discloses a novel lead-acid storage battery clapboard, which belongs to the technical field of storage batteries. The novel lead acid storage battery clapboard consists of the following raw materials in part by weight: 38 to 41 parts of superfine glass cellucotton, 7 to 10 parts of bicomponent organic fiber, 0.5 to 0.6 part of sulfuric acid, and 0.1 to 0.2 part of wet strength agent; and the novel lead acid storage battery clapboard is prepared through the processes of pulping, processing and conveying of sizing materials, paper-making from paper pulp for the clapboard, drying by a drying box, reeling, clapboard processing and the like. The lead-acid storage battery clapboard has the advantages of high porosity, low resistance, high wet strength and good anti-puncture capability, and compared with a pure glass fiber clapboard, the wet strength is improved by nearly 70 percent, the anti-puncture capability is improved by about 45 percent, and the wet resilience force is improved by 5 to 11 percent.

Description

Technical field:

[0001] The invention relates to a lead-acid storage battery separator and a preparation method thereof, belonging to the technical field of storage batteries. Background technique:

[0002] The separator is an important part of the lead-acid battery, known as the "third electrode". It is placed between the positive and negative plates of the battery, which can prevent the short circuit of the positive and negative electrodes in the electrolyte, and at the same time ensure that the electrolyte is in the positive and negative electrodes. There is good electrical conductivity between negative electrodes, and it also has the functions of reducing plate bending, preventing active material from falling off, good liquid retention, and gas passage. With the use of lead-acid batteries becoming more and more extensive, especially the rapid development of electric vehicles, the performance requirements for power batteries are getting higher and higher. As one of the fo...
