Embodiment 1

[0015] 1. The positive grid in grid 1 uses lead-calcium-tin-aluminum-silver five-element alloy, and silver is added to the existing lead-calcium-tin aluminum alloy, and the silver content accounts for 0.03% of the total weight of the alloy. The positive lead paste in lead paste 2 is added with 1.3% (weight percentage, the same below) of ultrafine rare earth oxide Y in the existing positive lead paste 2 O 3 , premix the dry powder for 45min-60min, then add water and acid for wet mixing; add 0.3% high-purity humic acid and 1.5% inorganic expansion agent ultrafine barium sulfate to the negative lead paste in the existing negative lead paste, grid After the paste is applied, the electrode plate 3 is made.

[0016] 2. The solidified and dried positive and negative plates are grouped according to 6 positive and 7 negative, and a total of 28 2V200Ah batteries are assembled. The pole group is pre-pressed on a special baler, the assembly pressure is set to 80kPa, and 2 cable ties 4 a...

Embodiment 2

[0023] Example 2: Take the most common type 2V500Ah battery as an example:

[0024] The silver content of the positive grid is 0.05% of the total weight of the alloy, and the Y in the positive lead paste formula 2 O 3 The ratio is 1.5%, and the rest of the process refers to Example 1, and small batch trial production is carried out, and a total of 150 2V500Ah batteries are assembled. Compared with ordinary batteries of the same type, the capacity and consistency of the batteries are better than those of ordinary batteries. The high temperature float charge at 60°C has been carried out 13 times, the capacity has dropped by 4.6%, and the number of large cycles is expected to reach about 20; Second, the product testing situation is basically the same as that of the high-temperature battery in Example 1, and the high-temperature performance of the product is also excellent.

Abstract

The invention provides a high temperature resisting deep-circulation lead acid battery, whose positive grid alloy employs silver-bearing alloy with high temperature and corrosion resistance and dehydration prevention, and rare earth oxide yttria is added into the anode lead paste formula, and a mixed expanding agent with high temperature resistance and oxidation prevention is added into the cathode lead paste formula. A battery housing and a top cover are made of PC / ABS alloy plastic with high temperature resistance. In order to satisfy the tight assembling requirement of the battery, the pole group is banded and packed into the housing, thereby guarantying the pole group assembling pressure does not change obviously during the usage period of the battery. The battery has effectively improved high temperature resisting deep circulation performance and service life, and is suitable for application in environment above 45 DEG C.

Description

technical field [0001] The invention relates to a high temperature resistant deep cycle lead-acid battery, which is mainly used in communication, post and telecommunications, banks and other places as a chemical power source. Background technique [0002] Under normal circumstances, the service life of ordinary lead-acid batteries will be shortened by half every time the ambient temperature rises by 10 °C. In the communication base station and the computer room, since the power supply equipment and the battery will generate a lot of heat during use, in order to improve the service life of the battery, the base station and the computer room are equipped with air-conditioning facilities to ensure that the battery ambient temperature is about 25 ℃ (generally not exceeding 28°C). The site's air-conditioning facilities have been in working condition for a long time, resulting in 45% of the total energy consumption of the equipment room being used for air-conditioning and other a...
