Description

technical field [0001] The invention relates to the field of power supply and can be used in wind energy, solar energy, communication, transmission and transformation systems, power plants, automobiles, pure electric vehicles, motorcycles, mopeds, mines, household appliances, lighting and the like. Background technique [0002] With the increasing scarcity of fossil energy, fossil energy has become an extreme problem faced by the world. In order to save energy, in 1859 the Frenchman Plant invented a kind of storage battery. The skin, separated by a rubber strip in the middle, is soaked in 10% sparse acid, and undergoes forward charging, stop, and reverse charging, and so on. The Englishman Sellon (Sellon) invented the lead-antimony alloy grid. This grid is combined with the Fur powder coating method to produce the so-called paste-coated plate. [0003] Since the 10s of the 20th century, the development of the automobile industry and the telephone industry has greatly promot...

Problems solved by technology

[0005] It is precisely because of the difference between the positive plate and the negative plate in the lead-acid battery that the positive current and the negative current must be collected and conducted separately, so it is necessary to use a metal grid or a metal bone grid to collect charges on the positive plate and the negative plate respectively. , and then conduct them through their respective tabs, and finally conduct the positive current and the negative current separately through the bus bar. It can be seen that the internal structure of the traditional lead-acid battery is not only complicated but also uses a large amount of metal (metal grid , metal bone grid, tabs and busbars, etc.) conduction means, which increases the internal resistance of the lead-acid battery, which further leads to an increase in the internal friction of the lead-acid battery and increases the heat generated by the lead-acid battery

When the lead-acid battery is discharged with a large current, the internal resistance increases sharply, and the voltage and current drop rapidly, so that the battery cannot fully discharge electric energy instantly, and due to the increase in internal resistance, the battery converts part of the electric energy into heat energy, resulting in The waste of electric energy and the heat generated at the same time can easily damage the battery

Furthermore, due to the increase of the internal resistance of the battery, the battery cannot be charged with a large current, and it needs a long time of slow charging, which is inconvenient for users to use. After the lead-acid battery is discharged, a large amount of lead sulfate is produced, and the lead sulfate forms resistance, which further increases The internal resistance of the battery makes it difficult to charge and discharge the battery, so the service life of the existing battery is very short

[0006] Under normal circumstances, the capacity of lead-acid batteries is generally designed according to the amount of active material (lead paste), and the negative electrode is designed to match the positive electrode, that is, it is designed to assist the positive electrode, because the negative electrode has no capacity, only the positive electrode releases Therefore, the capacity of the storage battery is limited by the capacity of the positive electrode and can only produce a localized capacity. The utilization rate of the active matter of the existing storage battery does not exceed 35%, which greatly wastes resources

[0007] In addition, in the production of existing lead-acid batteries, it is necessary to use chemical formation technology to make plates, and further operations such as welding the tabs and busbars of each plate are required. During the above operations, lead smoke and lead dust are formed , acid sewage and acid mist and other toxic and harmful substances affect human health and pollute the ecological environment
