Embodiment Construction

[0022] The present invention will be further described below in conjunction with specific embodiments to help understand the content of the present invention.

[0023] This alloy contains

[0024] Antimony (Sb): 1.5%~1.6%,

[0025] Arsenic (As): 0.12%~0.14%,

[0026] Tin (Sn): 0.18%~0.20%,

[0027] Selenium (Se): 0.03~0.04%,

[0028] Sulfur (S): 0.004~0.005%,

[0029] Copper (Cu): 0.04-0.05%.

[0030] The production process is as follows:

[0031] 1. Raw material preparation:

[0032] (1) Reduced lead-antimony content is greater than 1.8%, and zinc content is less than 0.001%.

[0033] (2) High antimony lead (with antimony content of more than 30%) (prepared on demand based on actual antimony content).

[0034] (3) Industrial arsenic with an arsenic content of more than 99% (prepared on demand based on the actual arsenic content).

[0035] (4) Industrial selenium with a selenium content of more than 97% (prepared on demand according to the actual selenium content).

[0036] 2. Ope...

Abstract

The lead based alloy material contains following elements in weight ratio: stibium 1.5%-1.6%, arsenic 0.12%-0.14%, stannum 0.18%-0.20%, selenium 0.03-0.04%, sulfur 0.004-0.005%, and copper 0.04-0.05%. The invention also discloses method for preparing the alloy material. The alloy material possesses advantages of low wastage of water, high circulation endurance, and high service life.

Description

Technical field [0001] The invention relates to an alloy material, in particular to an alloy material for battery grids. Background technique [0002] The grid alloy material of lead-acid batteries is one of the key technologies of high-energy fully enclosed lead-acid batteries. The performance of the grid directly affects the performance of lead-acid batteries. [0003] In the prior art, there are grids made of antimony alloy, calcium alloy and super calcium alloy, each of which has advantages and disadvantages. The traditional antimony alloy loses water quickly and has a short lifespan. After a period of time, the battery is prone to dry out and the life ends. Traditional calcium alloy: The water loss is small, but it is not suitable for deep cycle use. After dozens of deep cycles, the capacity will decline sharply and the life will end. Super calcium alloy: It can overcome the deficiencies of the above alloys, but the cadmium (Cd) in the alloy is highly toxic, pollutes the env...
