Problems solved by technology

So far, the positive and negative plates used in lead-acid batteries at home and abroad mainly include paste-type, formed-type, lead-cloth-type, lead-foil-type and tube-type plates. The lead-acid batteries composed of these plates have a maximum The characteristic and the biggest disadvantage are that the weight of the grid of the positive and negative plates accounts for more than 27% of the total weight of the battery, and the connecting lead parts of the positive and negative plates of the lead-acid battery also account for 5.8% of the total weight. More than 33% of the total weight of the acid battery, due to the existence of these lead grid lead parts, the specific energy of the current lead-acid battery is very low, only about 30wh / kg, which brings certain resistance to the application of the lead-acid battery
Especially in mobile equipment such as electric vehicles, automobiles, trains, and airplanes, it is even more cumbersome

Embodiment Construction

[0021] The present invention will be further elaborated below in conjunction with the accompanying drawings and embodiments.

[0022] The present invention includes a casing 6, a sealing frame 5, a negative output terminal 7, a positive output terminal 8, and a positive plate 3 installed in the casing 6, a negative plate 4, a glass fiber separator 2, a plastic-lead composite plate 1, and a plastic-lead composite plate. The pole plate 1 is composed of a composite pole plate 1-1, a thin cotton thread layer 1-2 arranged on the surface of the composite pole plate 1-1, and lead particles 1-3 embedded between the composite pole plates 1-1.

[0023] Composite plate 1-1 is a modified PVC thin plate with a thickness of 0.4mm, a shear size of 170×66mm, a punching diameter of Φ1.2mm, and a uniform distribution of hole density of 10×10mm.

[0024] The thin cotton layer 1-2 is made of 100g polypropylene fiber non-woven fabric, the cut size is 170×66mm, the punching diameter is Φ2mm, the de...

Abstract

The invention discloses a novel lead-acid storage battery with a plastic composite electrode plate, and is mainly characterized in that: a plastic lead composite plate is used as a substitute for lead grids and lead connecting pieces of the prior lead-acid storage battery; the plastic composite electrode plate is composed by a composite electrode plate, a cotton layer on the surface of the electrode plate and lead particles embedded in the composite plate. The invention has the advantages that: 1. improving the specific energy form the original 30 wh / kg to 50 wh / kg; 2. reducing the weight of the storage battery by 40 percent compared with the storage batteries with the same capacity; 3. reducing the consumption of lead with 6g for per square meter of the composite electrode plate, thereby greatly reducing the cost; 4. small inner resistance, heavy output currency, long service life; 5. connecting a dozen or more than hundreds of the same batteries to form a storage battery of dozens of volts or hundreds of volts.

Description

Technical field: [0001] The invention relates to a storage battery, in particular to a novel lead-acid storage battery with plastic-lead composite pole plates. Background technique: [0002] Lead-acid batteries are the most widely used batteries. So far, the positive and negative plates used in lead-acid batteries at home and abroad mainly include paste-type, formed-type, lead-cloth-type, lead-foil-type and tube-type plates. The lead-acid batteries composed of these plates have a maximum The characteristic and the biggest disadvantage are that the weight of the grid of the positive and negative plates accounts for more than 27% of the total weight of the battery, and the connecting lead parts of the positive and negative plates of the lead-acid battery also account for 5.8% of the total weight. More than 33% of the total weight of the acid battery, due to the existence of these lead grid lead parts, the specific energy of the current lead-acid battery is very low, only abou...
