Description

Novel lead-carbon battery

Technical Field

The invention relates to the field of lead-acid storage batteries, in particular to a novel lead-carbon battery.

Background

The lead-acid storage battery has undergone the development process of nearly 150 years, and the power battery has important commercial value due to high reliability, low cost, excellent high and low temperature performance and over 98% recovery rate, and still occupies a major market share in the field of low-speed electric vehicles (such as electric mopeds, electric motorcycles, and the like) up to now. However, the conventional lead-acid power battery cell (12V20Ah) has short cycle life (80% DOD, 300 cycles), high cell weight (7.2 kg), low power and poor high and low temperature performance (in southeast asia and northern cold regions in china), and thus limits the application development of the low-speed power vehicle with high safety, low cost and great commercial value.

The lead-carbon battery shell and the cover which are sold on the market at present adopt a single concave-convex embedded structure to strengthen the sealing of a joint part, and a gluing measure is additionally used to increase the sealing reliability. However, when a large-sized battery is transported or lifted, it is inevitable that the battery does not collide with the case, and a joint portion between the case and the cover is likely to be cracked. The obvious cracks can restore the sealing performance by repairing, and for some batteries with invisible cracks, the batteries are normally installed because the cracks are invisible, and when the batteries with the problems are recycled, the built-in electrolyte is easy to gradually seep out from the cracks. As is well known, the electrolyte in the lead-carbon battery is sulfuric acid, which is a strong corrosive agent and causes pollution to the surrounding environment once overflowing, especially corrosion of the battery frame. The dead battery rack inevitably constitutes the potential safety hazard of the lead-carbon battery pack, so that the user has higher requirements on the sealing performance of the lead-carbon battery for the energy storage scene.

In the prior art, chinese patent CN210349927U discloses a lead-carbon battery, which comprises a battery body, wherein terminals are fixedly mounted on both sides of the upper surface of the battery body, the upper surface of each terminal is connected with a screw head through a threaded hole, the upper surface of each screw head is fixedly connected with a pressing plate, the lower surface of each pressing plate is fixedly connected with an annular cover, an opening is arranged on the rear side of the outer surface of each annular cover, the outer surface of the battery body is fixedly wrapped with a rubber sleeve, the inner side surface of each rubber sleeve is fixedly connected with a plastic aluminum sheet, the outer surface of each plastic aluminum sheet is fixedly connected to the outer surface of the battery body, the pressing plates are connected with the terminals through threads, an annular cover structure with an opening is combined to facilitate the compression and fixation after the connection of electric wires, the loosening is avoided, and meanwhile, the rubber sleeve with the plastic aluminum sheet is sleeved on the outer side of the battery body, and the protection can be matched with the outer surface, this greatly improves the safety and stability of use, but still has the following disadvantages: because the terminal is connected through the mode of clamp plate, the power cord connects and has certain contact with the outside, takes place the electric shock accident easily to, the terminal need with the inside UNICOM of battery body, use for a long time and take place easily and leak, in case leak, electrolyte direct infiltration to the outside causes the pollution of environment easily.
