High-purity sulfuric acid (battery grade)

Description

1. Product Overview
This product is a high-purity, battery-grade sulfuric acid (H₂SO₄) engineered specifically for energy storage and industrial electrochemical applications. It serves as the critical electrolyte in lead-acid batteries—from automotive SLI to large-scale stationary storage systems. Its key value proposition lies in exceptionally low heavy-metal and organic contamination, ensuring superior cycle life and voltage stability. As global demand for reliable energy storage and uninterrupted power supply (UPS) grows, this strategic raw material directly impacts battery performance, safety, and total cost of ownership.

2. Key Specifications & Technical Characteristics

• Chemical composition: Sulfuric acid (H₂SO₄) 98.0% ± 0.5%, balance deionized water

• Purity grade: Battery grade (compliant with GB/T 625-2007, ASTM D546, or equivalent)

• Physical characteristics: Clear, colorless, odorless liquid; density 1.835–1.840 g/cm³ @ 20°C; viscosity 24–26 cP @ 20°C

• Critical impurities: Iron (Fe) ≤ 5 ppm; Chlorides (Cl) ≤ 3 ppm; Manganese (Mn) ≤ 2 ppm; Arsenic (As) ≤ 1 ppm; Nitrates ≤ 5 ppm; Heavy metals (as Pb) ≤ 10 ppm

• Packaging options: 35 kg HDPE jerrycans, 330 kg IBC totes, 1,600 kg bulk drums, or ISO-tank / flexitank for bulk industrial orders

• Shelf life: 24 months when stored in sealed, UV-protected containers between 5°C–35°C, away from organics and bases

3. Core Industrial Applications

• Automotive & motive power batteries: Used as electrolyte in starter, traction (forklifts, golf carts), and deep-cycle batteries – delivers higher cold-cranking amps (CCA) and lower self-discharge versus technical-grade acid.

• Telecom & UPS backup systems: Ensures stable specific gravity over 1,200 charge-discharge cycles, reducing premature battery failure in data centers and cell towers.

• Stationary energy storage (renewables integration): Outperforms standard acid by minimizing grid corrosion and sulfation, extending bank life by up to 18% in solar/wind installations.

• Recycling & secondary lead smelting: Employed in spent battery breaking and desulfurization – lower iron content reduces lead sulfate contamination, improving recovered lead purity.

4. Competitive Advantages

• Quality consistency: Statistical process control (SPC) across every batch; third-party SGS/Bureau Veritas certification available upon request.

• Supply reliability: Dedicated stainless steel / lined tanker fleet and dual-source raw material contracts ensure >99.5% on-time delivery, even during peak demand.

• Logistics capability: Port-to-plant delivery with real-time tracking; hazmat-certified warehousing in three continental hubs (Asia, EU, North America).

• Price competitiveness: Direct-from-refinery pricing with volume-based discounts; hedging options for long-term contracts (6–24 months).

• Sustainability: Zero-liquid-discharge (ZLD) manufacturing; recycled acid content up to 30% without performance loss; full REACH and RoHS compliance documentation.

• Technical support: On-call chemical engineers for formulation adjustment, dilution protocols, and safety data sheets (SDS) in 12 languages.

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 20 MT (one bulk truckload or ISO-tank)

• Loading capacity: 24 MT per standard 20-foot container (IBC totes or drums); 26 MT per ISO-tank container
