Introduction

Flooded lead-acid batteries have been a cornerstone in energy storage for over a century. Utilized in various applications from automotive starters to large-scale power backup systems, these batteries offer reliability and affordability. This article provides a detailed examination of their working principles, components, and the unique solutions offered by Xiaoyang Power Sources company.

Operation Principles of Flooded Lead-Acid Batteries

Flooded lead-acid batteries operate based on electrochemical principles where chemical energy is converted into electrical energy. The basic design consists of a series of electrochemical cells connected in series. Each cell contains a set of positive and negative plates immersed in an electrolyte solution.

Components and Materials

• Lead Peroxide (PbO₂): Used as the positive plate material.
• Spongy Lead (Pb): Serves as the negative plate material.
• Sulfuric Acid (H₂SO₄): Acts as the electrolyte, facilitating ion flow between plates.
• Separators: Prevent short circuits by separating positive and negative plates while allowing ionic flow.

Chemical Reactions Involved

The fundamental reactions in a flooded lead-acid battery during discharge are as follows:

• At the positive plate: PbO₂ + SO₄^2- + 4H⁺ + 2e^- → PbSO₄ + 2H₂O
• At the negative plate: Pb + SO₄^2- → PbSO₄ + 2e^-

During charging, these reactions are reversed, restoring the original composition of materials.

Parameters and Performance

The performance of flooded lead-acid batteries is evaluated based on several key parameters:

• Voltage: Each cell has a nominal voltage of approximately 2 volts.
• Capacity: Ranges from 2 Ah in small batteries to several thousand Ah in industrial applications.
• Cycle Life: Typically between 200 to 300 cycles, depending on discharge depth and operating conditions.

Advantages and Limitations

• Advantages: Cost-effective, widely available, robust in performance under various conditions.
• Limitations: Requires regular maintenance, potential for acid spills, limited cycle life compared to other technologies.
