Problems solved by technology

You must produce as much as you want and sell as much as you want, otherwise, you will have to charge and protect the lead battery from time to time, wasting power resources and reducing the sales price of the product
[0023] In summary, the irreversible degeneration of lead batteries caused by the special self-discharge and "float charge" of lead batteries is the result of the inactivation of active materials, increased internal resistance, low energy utilization efficiency, safety hazards and end-of-life of traditional lead batteries. root cause, and its course cannot be changed by "fair use"

Abstract

The invention belongs to the field of electric energy storage, and in particular relates to a lead-acid storage battery plate, a lead-acid storage battery and a preparation method and application thereof. The present invention uses inert material metal barium, lead-barium alloy, and sulfuric acid solution as raw materials. After rolling, the lead sulfate is extruded into the barium metal plate, so that the lead sulfate is separated, and the metal barium forms a stable and reliable structure at the same time. The conductive network of "boron trioxide-silicon dioxide" applied afterwards further seals and isolates the lead sulfate particles, while the "boron trioxide-silicon dioxide" colloidal layer does not hinder the sulfate ion And the transmission of hydrogen ions, and then get the lead-acid battery plate. The invention effectively overcomes the irreversible denaturation of the traditional lead-acid storage battery during use, the conductive network of the plate can maintain stability for a long time, the active material is separated in the micro-grid of the conductive network, and almost all of them can participate in the charge and discharge cycle repeatedly , so that the lead-acid battery can achieve long life.

Description

technical field [0001] The invention belongs to the field of electric energy storage, and in particular relates to a lead-acid storage battery plate, a lead-acid storage battery and a preparation method and application thereof. Background technique [0002] In the secondary power supply, lead-acid batteries (hereinafter referred to as lead batteries), compared with lithium batteries, although their weight specific energy is lower, but it has abundant raw materials, relatively safe, easy maintenance and regeneration, and can be discharged with a large current. and other advantages. After research, it is found that there are five major disadvantages in current maintenance-free lead batteries, making them facing the fate of being eliminated. If you can find out the shortcomings of its structure, give full play to its advantages, greatly improve its performance, especially if it can achieve long life, then it is still very useful in areas where weight is not a concern. The fiv...
