Core Factory Strengths: Compliance, Technology & Scale

1. Environmental Compliance & Green Production (Policy-Aligned)

Our factory fully implements national environmental protection requirements (referenced to 2025 environmental approval standards) with systematic pollution control measures:

Waste Gas Treatment:

Batching dust collected via vacuum feeding system + bag filter, discharged through 15m exhaust stack (DA001) with particulate matter ≤0.0011t/a.

Coating/drying NMP waste gas treated by triple water spray + activated carbon adsorption (DA002), and electrolyte injection waste gas by dual activated carbon adsorption (DA003), ensuring VOCs emission ≤0.0695t/a, meeting Battery Industry Pollutant Emission Standard (GB30484-2013) and Henan Province Grade A emergency emission reduction indicators.

Wastewater Management: Domestic sewage treated by septic tank for agricultural reuse; circulating cooling water recycled for factory cleaning, achieving zero wastewater discharge.

Solid Waste Disposal:

General waste (waste cartons, electrode scraps, diaphragm) classified and recycled; dust from bag filters reused in production.

Hazardous waste (spent activated carbon HW49, waste lubricating oil HW08) stored in 10m² compliant temporary storage room (GB18597-2023 standard) with anti-leakage/anti-corrosion measures, transferred via official waste transfer manifests to qualified disposal units.

Noise Control: Vibration damping + sound insulation equipment installed for production machinery, ensuring daytime factory boundary noise meets GB12348-2008 Class 2 standards.

2. Precision Automation Production (Tsinghua-Technology Supported)

Equipped with 12 fully automated production lines from Lith Corporation (Tsinghua-founded equipment manufacturer with 16+ patents), achieving industry-leading process control:

Key Equipment Configuration:

Precision film coater (coating thickness error ≤2μm), high-pressure roller press, and intelligent mixer, ensuring uniform electrode manufacturing.

Vacuum glove box injection system (dew point ≤-30℃) and automatic winding machine (alignment accuracy ≤0.1mm), maximizing active material utilization in AAA form factor.

Online Quality Monitoring:

In-line HI-POT high-voltage testing for internal short circuit detection; ICP-MS real-time impurity analysis (heavy metals ≤10ppm, harmful elements ≤10ppb).
