Technique for making polar plate of dried-charge tube-type dynamic lead acid battery

Abstract

The invention provides a formation process for a polar plate of a dry-charged tube type power lead-acid battery, comprising the preparation of the polar plate, solidification and drying, formation, washing, the soakage of a negative plate, and drying and manufacturing of the polar plate. The formation process is characterized in that the solidification and drying process of the polar plate comprises the following stages: the first stage is the solidification stage which is performed at a temperature of between 35 and 45 DEG C, and the humidity above 95 percent for 24 hours; the second stage is the drying stage which comprises two stages, wherein the first drying stage is performed at a temperature of between 40 and 50 DEG C, and the humidity between 60 and 70 percent for 24 hours; and the second drying stage is performed at a temperature of between 65 and 75 DEG C, and the humidity between 40 and 50 percent for 24 hours. With the invention, Pb02 of a positive plate is more than or equal to 85 percent, Pb of the negative plate is more than or equal to 85 percent, and the water content in the polar plate is below 0.5 percent. Under the conditions of the same volume and the same weight, the capacity and the service life of the polar plate exceed the common battery by 10 to 15 percent; and the dry-charged performance of the polar plate is as follows: initial charge is not needed after liquid is added, and the polar plate can be used after standing for 4 hours.

Description

technical field [0001] The invention relates to the field of a lead-acid storage battery for traction with high specific energy, in particular to a formation process of a pole plate of a dry-loaded tube type power storage battery. Background technique [0002] Ordinary power batteries need to be charged after adding acid before use. This kind of battery has great disadvantages: the user is limited to the understanding of the battery, and the initial charge cannot be operated as required, which affects the capacity and service life of the battery. Good batteries leave the factory and cannot be sold in time, resulting in sulfation of the battery, which will also affect the capacity and service life of the battery; the initial charging method is different from the ordinary charging method, and the choice of chargers is limited; the initial charging time is long, which increases the user use cost. [0003] High performance power dry charge battery, it has high performance: high...

Problems solved by technology

In terms of power batteries, so far, other domestic manufacturers have not made progress. Internationally, they have only shortened the initial charging time. The original initial charging time of power batteries is 72 hours. It can only shorten the initial charging time to 24-28 hours, but it fails to reach the dry charging level
