Embodiment Construction

[0020] The invention improves the fluidity and corrosion resistance of the lead alloy by changing the material of the lead alloy in the prior art, can effectively reduce scum, and avoid problems such as virtual welding, false welding, and missing welding. The present invention will be described in detail through specific examples below. In the following description, unless otherwise specified, all percentages are percentages by weight.

[0021] The specific embodiment of the present invention provides a lead alloy. The composition and mass percentage of the lead alloy are as follows: tin Sn can be 0.1% to 2.0%; selenium Se can be 0.001% to 1.0%; the rest is lead Pb; the Sn The purity is 99.9% and above, the purity of Se is 99.5% and above, and the purity of Pb is 99.9% and above.

[0022] Preferably, the composition of the above-mentioned lead alloy and the specific mass percentage content of each composition are as shown in Table 1:

Abstract

The embodiment of the invention provides an aluminum alloy and application and a production method of the aluminum alloy and relates to the chemical field. The aluminum alloy includes: 0.1-2.0 percent of Sn; 0.001-1.0 percent of Se; and the balance of Pb. The purity of Sn is 99.9 percent or above, the purity of Se is 99.5 percent or above, and the purity of Pb is 99.9 percent or above. The specific embodiment also provides applications of the aluminum alloy and a production method thereof. The technical proposal provided by the invention has the advantages of good liquidity, corrosion resistance and prolonged service life of batteries.

Description

technical field [0001] The invention relates to the field of chemical industry, in particular to a lead alloy used in a valve-regulated sealed lead-acid battery and its application and production process. Background technique [0002] Valve-regulated sealed lead-acid batteries (VRLA) were widely promoted and used abroad in the late 1970s due to their less maintenance, less pollution and excellent cost performance, and won the welcome of users. However, in the mid-1980s, many foreign VRLA battery manufacturers successively discovered battery failures caused by negative electrode tabs and busbar corrosion (Negative Group Bar Corrosion, NGBC). At that time, the welding technology of the bus bar was the same as that of the flooded battery. Although the flooded battery had been used safely for many years, the VRLA battery had a negative electrode crisis. [0003] In order to solve the above problems, the prior art adopts cast welding to manufacture lead-acid batteries, which cas...
