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 roll-type lead-acid storage battery and its preparation method and application. 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. Conductive network; after that, the colloidal layer of boron trioxide-silica is applied to further seal and isolate the lead sulfate particles. The components are assembled to obtain a roll-type lead-acid battery. The invention effectively overcomes the irreversible denaturation of the traditional lead-acid storage battery during use, and its plate conductive network can maintain stability for a long time, and the active material is separated in the micro-grid of the conductive network, which can almost completely participate in the charge-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 roll-type lead-acid storage battery and its preparation method and application. Background technique [0002] Among the secondary power sources, lead-acid batteries (hereinafter referred to as lead batteries) account for more than 90% of the total storage capacity (excluding fuel cells) in terms of electric energy storage capacity. Compared with lithium batteries, although its weight specific energy is lower, it has the advantages of abundant raw material sources, relatively safe, easy maintenance and regeneration, and high current discharge. However, there are currently five major drawbacks to maintenance-free lead batteries. [0003] First, the service life is generally 2 to 3 years, and some are even less than 2 years. In the technical research field of lead batteries, the current research mainly focuses on the "carbon doping" of the positive and negative...
