example 1

[0009] Example 1: Weigh the following raw materials to prepare lead-calcium alloy: lead 9860g, calcium 15g, tin 120g, aluminum 5g; weigh the following raw materials to prepare lead-antimony alloy: lead 9600g, antimony 250g, tin 100g, arsenic 7g, copper 5g, silver 28g, selenium 10g. Use lead-calcium alloy and lead-antimony alloy to make grids A and B respectively, and use grids A and B to make positive plate A respectively + and B + , use grid A to make negative plate A - . Take 3 positive plates B + , 12 positive plates A + , 15 negative plates A - , plus a diaphragm, combined into a pole group, of which 3 positive plates B + Separately placed inside the pole group. The combination method of the pole group is casting welding. Before casting welding, the pole lugs of the pole plate are ground and chamfered, pre-soaked in phosphoric acid aqueous solution with a mass percentage concentration of 12%, and then dipped in lead-tin with a mass ratio of 1:1 and a temperature of ...

[0010] Example 2: Weigh the following raw materials to prepare lead-calcium alloy: lead 9970g, calcium 6g, tin 21g, aluminum 3g; weigh the following raw materials to prepare lead-antimony alloy: lead 9880g, antimony 100g, tin 10g, arsenic 2g, copper 2g, silver 3g, selenium 3g. Take 1 positive plate B + , 9 positive plates A + , 10 negative plates A - , plus the diaphragm, combined into a very group by casting welding. Before casting and welding, the concentration of phosphoric acid aqueous solution dipped is 15% (weight), the content ratio (weight) of lead-tin alloy is 1:1, the temperature is 280°C, the lead melt for casting and welding contains 2% (weight) tin, and the temperature is 500°C. All the other expressions are the same as example one.

Abstract

The invention discloses a manufacturing process of an electrode group of a lead-acid battery, the manufacturing process is characterized in that a plate grid of a positive electrode plate in the electrode group is respectively manufactured by two complex alloys, one is the lead-calcium complex alloy, the other is the lead-antimony complex alloy, the plate grid of a negative electrode plate is manufactured by the lead-calcium complex alloy, the positive electrode plate and the negative electrode plate are combined to the electrode group by adopting the cast welding method after manufacturing the plate grids, phosphoric acid water solution and lead-tin alloy (liquid) are pre-impregnated before the cast welding, and then tin-lead solution with the temperature of 480 DEG C-500 DEG C is used for completing the cast welding. The process is used for manufacturing the electrode group of the lead-acid battery and can effectively improve the electrical performance of the electrode group, can lead the voltage of various batteries to be consistent when charging a battery pack, cause the acceptance of the batteries to the power to be consistent, avoid the production of low batteries and further can improve the service life of the battery pack.

Description

technical field [0001] The invention relates to a manufacturing process of a lead-acid storage battery pole group, in particular to an alloy material used in making a grid in the pole group and a combination method of the pole group. Background technique [0002] Lead-acid battery occupies a pivotal position in the field of secondary batteries by virtue of its excellent performance-price ratio. Among all aqueous solution power systems, lead-acid batteries have higher operating voltage, better high-current discharge performance and high-low temperature discharge performance, and are suitable for both floating charge use and starting and cycle use. Therefore, lead-acid batteries are widely used in fields such as backup power supply, energy storage, and power energy. [0003] Although the valve-regulated sealed lead-acid battery (hereinafter referred to as VRLA battery) technology has become increasingly mature, there are some problems in use because VRLA batteries are always ...
