• Patent Number: 10-2741628 (Registration Date: December 12, 2024)

In the rapidly growing secondary battery market, improving battery quality and productivity has emerged as a crucial challenge. Traditional wet coating processes in electrode manufacturing have faced several technical limitations. The wet process, which uses solvents, often results in quality degradation due to issues such as pinhole formation, cracking during the drying process, and powder floating caused by solvent evaporation.

To fundamentally address these challenges, PNT has developed an innovative dry electrode double-side coating technology. This technology, recently patented (Patent No. 10-2741628), is expected to open new horizons in secondary battery manufacturing processes.

The most distinctive feature of PNT's dry electrode double-side coating equipment is its unique roller arrangement structure. The pressing roll system, designed in an 'L' shape, maximizes space efficiency by arranging rollers both horizontally and vertically. This structure enables stable coating performance while minimizing the overall equipment footprint.

The precision control system is another core technology of this equipment. The gap adjustment mechanism allows precise control of electrode thickness by finely adjusting the spacing between rollers. Additionally, an automatic tension control system maintains consistent quality during continuous production. Notably, the heating rod system maintains optimal electrode material conditions by precisely controlling temperatures below 200°C.

The equipment consists of five main components:

1. Collector Supply Unit: Continuously supplies foil of uniform width
2. First Electrode Forming Unit: Forms the first electrode layer by rolling electrode powder
3. Tension Control Unit: Stabilizes tension variations during the process
4. Second Electrode Forming and Coating Unit: Forms the opposite electrode layer and performs simultaneous double-side coating
5. Winding Unit: Winds up the completed electrode

These technical features offer significant advantages in terms of productivity and quality:

• Continuous production capability with simultaneous double-side coating increases production efficiency
• Compact design enables efficient use of factory space
• Precise control system ensures uniform electrode quality
• Eliminates solvent-related issues found in wet processes

The global secondary battery market is experiencing explosive growth, driven by increasing electric vehicle demand. In this context, PNT's dry electrode double-side coating technology offers an innovative solution that simultaneously addresses cost reduction and quality improvement challenges. This is particularly significant for electric vehicle battery production, where electrode manufacturing efficiency is crucial.

This patent demonstrates PNT's technological leadership in the secondary battery manufacturing equipment market. The technology is expected to play a vital role in:

• Streamlining EV battery production
• Reducing manufacturing costs
• Improving battery quality and consistency
• Enhancing overall production efficiency
