Embodiment Construction

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

[0023] This alloy, in a lead base contains

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

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

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

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

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

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

[0030] Its production process is as follows:

[0031] 1. Raw material preparation:

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

[0033] (2) High antimony lead (antimony content above 30%) (prepared according to actual antimony content).

[0034] (3) Arsenic for industrial use with an arsenic content above 99% (prepared according to actual arsenic content).

[0035] (4) Selenium for industrial use with a selenium content above 97% (prepared on demand according to the actual sele...

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 a lead-acid storage battery grid. Background technique [0002] The grid alloy material of the lead-acid battery is one of the key technologies of the high-energy fully enclosed lead-acid battery, and the performance of the grid directly affects the performance of the lead-acid battery. [0003] In the prior art, there are grids made of antimony alloy, calcium alloy and ultra-calcium alloy, each of which has advantages and disadvantages. Traditional antimony alloys lose water quickly and have a short lifespan. After a period of use, the battery is prone to dry out and its lifespan 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 shortcomings of the above alloys, but the cadmium (Cd) in the all...
