Introduction

Acid batteries, commonly known as lead-acid batteries, have been a reliable source of power for various applications since their invention in the 19th century. These batteries are widely used in automotive, industrial, and renewable energy applications due to their cost-effectiveness and reliable performance.

Working Principle of Acid Batteries

Lead-acid batteries operate on the principle of electrochemical reaction between lead dioxide (PbO₂) and sponge lead (Pb) in the presence of a sulfuric acid (H₂SO₄) electrolyte. The battery consists of a positive plate made of lead dioxide, a negative plate made of sponge lead, and an electrolyte composed of a diluted sulfuric acid solution.

Chemical Reactions

The essential chemical reactions in a lead-acid battery are as follows:

• During discharge:
  • PbO₂ + 4H⁺ + SO₄^2- + 2e^- → PbSO₄ + 2H₂O
  • Pb + SO₄^2- → PbSO₄ + 2e^-
• Overall discharge reaction:
  • PbO₂ + Pb + 2H₂SO₄ → 2PbSO₄ + 2H₂O
• During charging, the reactions are reversed, restoring the original materials.

Performance Characteristics

Lead-acid batteries have specific parameters that define their performance, which include:

• Voltage: Typical nominal voltage of 2 Volts per cell, with a 12V battery usually consisting of six cells.
• Capacity: Measured in ampere-hours (Ah); the capacity determines the discharge duration.
• Efficiency: Generally around 75-85% for lead-acid batteries.
• Temperature range: Optimal performance is typically between -20°C to 50°C.
• Lifespan: Varies depending on the depth of discharge, temperature, and maintenance, usually lasting 3-5 years in average conditions.
