Lead-acid batteries, as one of the most mature electrochemical energy storage technologies, rely heavily on the quality of their battery plates. The manufacturing of battery plates integrates precision processes from metallurgy, chemistry, and materials science. This article delves into the full production process of green plates (unformed plates), from raw materials to final shaping, revealing the modern industrial wisdom behind this traditional technology.

I. Raw Material Preparation: Metallurgical Purification of High-Purity Lead

1. Lead Ingot Melting

We utilize electrolytic lead ingots with a purity of ≥99.99%, which are melted into liquid lead in a lead melting furnace at 450-500°C. To enhance mechanical strength, alloying elements are added in proportion:

Positive Plates: 0.3%-1.2% antimony (Sb) is added to enhance corrosion resistance;

Negative Plates: Lead-calcium alloy (0.08%-0.12% Ca) is used to reduce the risk of hydrogen evolution.

2. Lead Powder Preparation (Lead Oxide Generation)

Molten lead is atomized into micrometer-sized lead particles through a lead powder machine (using the Barton method or ball milling method). These particles react with air in an oxidation chamber to form porous lead oxide (PbO):

2Pb + O₂ → 2PbO

The lead powder has a particle size controlled at 2-5μm and a specific surface area of 0.8-1.5 m²/g, ensuring high reactivity for subsequent reactions.

II. Paste Preparation: The Core Carrier of Electrochemical Active Substances

1. Formula Mixing

Lead oxide powder, deionized water, sulfuric acid (density 1.40g/cm³), and fibrous additives (such as lignin) are mixed in proportion in a paste mixer:

Positive Plate Paste: Lead powder:Sulfuric acid:Water ≈ 100:8:12, forming a porous PbO·PbSO₄ framework;

Negative Plate Paste: Expanding agents (such as carbon black, barium sulfate) are added to inhibit passivation.

2. Paste Maturation

The mixed paste is left to mature in an environment at 35-45°C with humidity >90% for 8-12 hours, completing the following reaction:

4PbO + H₂SO₄ → 3PbO·PbSO₄·H₂O + H₂O

This forms a stable basic lead sulfate network structure, with the paste density reaching 4.0-4.3g/cm³.

III. Grid Manufacturing: The Mechanical Framework of Battery Plates

1. Alloy Casting

Using die-casting or continuous expanded mesh processes, lead-calcium/lead-antimony alloys are formed into grid-like structures:

Thickness: Positive plates 1.8-2.5mm, negative plates 1.2-1.8mm;

Grid Design: Diamond or radial patterns to reduce internal resistance and enhance active material adhesion.

2. Surface Treatment

The grids are cleaned with dilute sulfuric acid (5%) to remove oxide layers, forming a micro-rough surface to enhance paste adhesion.

IV. Coating and Curing: Precision Shaping of Active Materials

1. Automated Coating

Grids are evenly coated with paste using a double-belt coater, with precise paste application within ±0.5g per plate. The thickness is controlled by rolling (positive plates 2.5-3.0mm, negative plates 1.8-2.2mm).

2. Curing and Drying

The coated plates undergo a three-stage curing process in a humidity-controlled tunnel kiln:

Surface Drying (40°C, 2h): Rapid dehydration to prevent cracking;

Crystal Transformation (65°C, 12h): PbO·PbSO₄ → 4PbO·PbSO₄;

Final Drying (50°C, 6h): Residual moisture <0.5%.

This results in porous, high-mechanical-strength green plates (positive plates PbO/PbSO₄, negative plates sponge-like Pb).

V. Quality Control: Precision Manufacturing Empowered by Digitalization

Online Inspection: X-ray thickness gauges monitor paste uniformity in real-time;

Physical Indicators: Plate hardness (Shore A 50-65), bending strength (>15MPa);

Electrochemical Pre-testing: Random sampling for 0.5C discharge testing, with capacity deviation ≤3%.

VI. Environmental Protection and Innovation: The Industrial Revolution of Green Manufacturing

Lead Dust Control: Fully enclosed production lines with bag filters, lead emissions <0.1mg/m³;

Paste Recycling: Centrifugal separation technology achieves a paste reuse rate >95%;

Smart Factory: MES systems optimize process parameters at the millisecond level, reducing energy consumption by 18%.

The manufacturing process from lead ingots to green plates represents the perfect integration of materials science and engineering technology. Kaiying Power ensures that each battery plate combines high energy density with ultra-long cycle life through full-process digital control and green process innovation, providing a reliable power core for global energy storage systems.

During market research, we identified counterfeit products through various issues on the battery casing, including:

Poor Casing Quality: Counterfeit batteries have thin casings with numerous scratches.

Inferior Silk-Screen Printing: The silk-screen printing on counterfeit batteries contains errors in text, data, and certification codes, and is often blurry. These issues not only affect the product's appearance but also indicate unstable internal quality.

Irregular Date Coding: The date coding on counterfeit batteries is irregular and does not accurately reflect the production date.

Irregular Terminals and Acid Leakage: The terminals on counterfeit batteries are poorly made and prone to acid leakage and corrosion, which can lead to unstable connections, affecting the battery's performance and safety.

These subtle differences, though easily overlooked, are crucial in quality control. Our batteries feature clear and accurate silk-screen printing, consistent laser date coding, and well-made terminals with strict prevention of acid leakage. This discovery further strengthens our commitment to quality and reminds us to focus more on detail presentation and education in market promotion. Below are some examples:

2. Comprehensive Harms of Substandard Lead-Acid Batteries to Equipment

The impact of substandard lead-acid batteries on equipment is multifaceted, mainly reflected in the following aspects:

Performance and Lifespan

Difficulty in Starting and Unstable Operation: Due to poor quality electrode materials and electrolyte, substandard batteries have increased internal resistance and rapidly decreasing discharge voltage. This not only makes it difficult to start equipment, such as motorcycles failing to start, but also causes voltage fluctuations during operation, leading to unstable equipment performance, like frequent restarts of data center servers.

Shortened Lifespan: Poor material quality can lead to incomplete chemical reactions and electrode material shedding, causing the battery capacity to drop quickly and shortening its lifespan. This increases the maintenance cost and downtime of equipment, such as the need for frequent battery replacements in UPS systems.

Safety and Environment

Equipment Damage and Safety Risks: Leakage and expansion issues can cause electrolyte to corrode the metal parts and electronic components of equipment, causing damage. Moreover, the poor quality casing of substandard batteries can easily break, potentially causing short circuits, overheating, and even fires, endangering personnel and property safety.

Environmental Pollution: Substandard batteries are prone to leaking harmful substances, such as lead and acid, during use and disposal, posing a threat to the ecological environment and human health. Discarded substandard batteries can contaminate soil and water sources if not disposed of properly.

Economy

Increased Maintenance Costs: Due to unstable performance, frequent inspections and maintenance are required, and the replacement frequency is high, which significantly increases the maintenance cost of equipment, affecting its economic efficiency and usability.

Faced with counterfeit and substandard lead-acid batteries in the market, we understand the importance of protecting consumer rights and maintaining market order. Through strict quality control, we ensure that every battery meets high-quality standards. We not only strictly monitor the production process but also focus on detail presentation and education in market promotion to help consumers identify genuine products.
