Problems solved by technology

The lead-acid battery produced in this way has poor binding force and uniformity of active materials and poor conductivity, resulting in poor charge and discharge performance and deep cycle life, so it can only be used as a spare battery for shallow cycles.
This can be used normally u

Example Embodiment

[0008] Below further illustrate the present invention by embodiment:

[0009] The components and mass percent content of example one and example two active materials are:

[0010]

[0011] The preparation method of example one, example two active materials is: after getting the raw material ready by each component mass percentage, lead powder, binding agent and lead sulfate catalyst are stirred and mixed 10min (example one) or 15min (example two) under dry state, Then add deionized water at a constant speed within 6 minutes, stir while adding, continue to stir for 6 minutes (Example 1) or 8 minutes (Example 2) after the addition, and then add sulfuric acid, the acid adding time is 10min (Example 1) or 15min (Example 2 ), stirring while adding, and continuing to stir for 15min (Example 1) or 10min (Example 2) after adding the acid. During the preparation process, the paste temperature was controlled to be 70-75°C.

Abstract

The invention discloses an anode active material of a valve-regulated sealed lead acid battery for communication and a preparation and curing method thereof. The method has the following steps: adding a lead sulfate catalyst in lead powder, a bonding agent, sulfuric acid and deionized water; stirring the mixture fully at the temperature below 80 DEG C, thus obtaining a lead plaster; and curing by three high-temperature high-humidity steps after smearing at the temperature of 50-60 DEG C. The active material tissue is fine and uniform, has a greater specific surface area, has high bonding force with a grid, and has good electric conductivity; the charge and discharge performances and deep circulation service life of the prepared lead acid battery are improved prominently, and the material provided by the invention is applicable to large current and deep discharge circulation.

Description

technical field [0001] The invention relates to an active material for a lead-acid battery pole plate, in particular to a valve-controlled sealed lead-acid battery positive active material for communication, and a method for preparing the active material and curing it after smearing. Background technique [0002] Information technology is becoming more and more important to the development of human society, especially in the fields of military and communication. my country's communication industry has entered an era of rapid development, and signal coverage in various regions and various network optimization projects require safe, reliable, efficient, and energy-saving power guarantees without exception. The positive electrode active material used in the existing lead-acid battery is mixed with lead powder, binder, sulfuric acid and water as raw materials, and then smeared and then solidified at a low temperature to make a battery pole plate. The lead-acid battery produced ...
