Abstract

The invention provides a lead-acid storage battery, and belongs to the technical field of storage batteries. The lead-acid storage battery comprises a shell, a positive plate, a negative plate, a positive pole connected with the positive plate and a negative pole connected with the negative plate; each of the positive plate and the negative plate comprises a frame main body, supporting ribs, a conductive wire and lead plaster coating the frame main body. According to the lead-acid storage battery provided by the invention, the conductive wire is wound on the frame main body, the conductive wire is supported by the frame main body, the metal consumption of the conductive wire and the loss of a lead raw material are greatly reduced, and the frame main body and the supporting ribs are both made of an acid-corrosion-resistant material, so that the service life can be prolonged; a plurality of lead coil groups are sequentially arranged in the frame main body at intervals, so that the contact area of the conductive wire and acid liquor is increased, a grid can be made to be lighter and thinner, the utilization rate of active substances is improved, the capacity of the battery with the same size as those in the prior art can be made to be higher, or the mass of the active substances of the battery with the same capacity as those in the prior art is small, and the gravimetric specific energy of the battery is improved.

Description

technical field [0001] The invention belongs to the technical field of accumulators, and more specifically relates to a lead-acid accumulator. Background technique [0002] Lead-acid battery is currently the most widely used chemical energy storage power source in the world. It has the advantages of stable voltage, safety and reliability, low price and high recycling rate. It is widely used in automobile starting, industrial energy storage, power supply and other fields. It is closely related to human life. Among them, the electrodes of lead-acid batteries are mainly made of lead and its oxides, and the electrolyte is a battery of sulfuric acid solution. However, most of the existing lead-acid batteries in use have the problems of large lead consumption in the manufacture of electrode grids and low weight-to-energy ratio of the batteries. Contents of the invention [0003] The object of the present invention is to provide a lead-acid storage battery, aiming at solving th...
