Embodiment 1

[0136] Such as figure 1 -6. The current collector of the lead-acid battery in this embodiment is one or more of a flat plate 1 , a coiled plate or an arc plate 2 , an orifice plate 3 , a grid or grid 5 , an array 7 , and a comb plate 9 .

[0137] Such as Figure 7 As shown, the lead-acid accumulator current collector plate of the present embodiment includes an upper surface lead skin 12 and a lower surface lead skin 13, a light conductor aluminum 14, an edge-sealing material lead-tin alloy solder 15, and the materials of the lead skins 12 and 13 are all It is metallic lead; the lead skins 12, 13 and the light conductor aluminum 14 are laminated with each other to form a three-layer laminated structure 16, wherein the light conductor aluminum 14 is between the lead skins 12, 13, and is connected with the lead skins 12, 13 Carry out conductive connection; Edge-sealing material lead-tin alloy solder 15 is positioned at the edge of described 3-layer laminated structure 16, throug...

Embodiment 2

[0142] The difference from Example 1 is that, as Figure 8 As shown, the current collector of the lead-acid battery in this embodiment is covered with conductive anti-corrosion layers 17, 18 on the upper and lower surfaces of the light conductor aluminum 14, which are stacked together with the lead skins 12, 13 to form a five-layer stack Structure 19, the light conductor aluminum 14 conducts conductive connection with the lead skin 12 or 13 through the anti-corrosion layers 17, 18, and the edge-sealing material lead-tin alloy solder 15 is located at the edge of the 5-layer laminated structure 19. Through the welding process, the sealing Edge material lead-tin alloy solder 15 is welded together with lead skin 12,13, conductive anti-corrosion layer 17,18, light conductor aluminum 14, and edge sealing material lead-tin alloy solder 15 is welded on lead skin 12,13 Together, a closed space surrounded by the three is formed, and the light conductor aluminum 14 and the conductive ant...

Embodiment 3

[0146] The difference from Example 1 is that, as Figure 9 As shown, the current collector of the lead-acid battery in this embodiment, at the edge of the laminated structure 16, the edge-sealing material lead-tin alloy solder 15 is welded and combined with the edges of the lead skins 12 and 13 in the space between the lead skins 12 and 13 Together.

Abstract

The invention discloses a lead-acid storage battery current collector. The lead-acid storage battery current collector comprises a lead sheath, a light conductor and an edge sealing material; the leadsheath and the edge sealing material are combined together; the light conductor is wrapped and enclosed in an enclosed space to enable the light conductor and an external environment space of the current collector not to be communicated with each other so as to be isolated from each other; and the light conductor is conductively connected with the lead sheath. The invention further discloses a manufacturing method and tool of the current collector and a lead-acid storage battery comprising the current collector. The manufacturing method and tool of the current collector are beneficial to manufacturing the current collector. According to the current collector, the weight of the current collector of the lead-acid storage battery, and the usage amount and cost of lead materials can be greatly reduced, and the conductivity of the current collector can be improved. The lead-acid storage battery comprising the current collector has remarkably improved performance in multiple aspects, such as specific energy, capacity, high-current charging and discharging capacity, internal resistance, polarity inversion performance, environmental protection, cost, service life and the like.

Description
