2. Parameter–Scenario Deep Integration: Single-Sided for Lab Use, Double-Sided for Industrial Transition

2.1 Single-Sided Electrodes (NFPP-S01–S06): The Core Platform for Coin Cell Material-Level Validation

Single-sided electrodes, with their wide range of areal densities and coating processes, serve as the central platform for coin-type half/full cell validation:

• Parameter Adaptability: Areal density spans 10–31 mg/cm², with coating processes including wet (S01, S02, S03, S05, S06) and dry (S04) methods, enabling comprehensive performance screening under various loading and process conditions.
• Application Scenarios: Suitable for validating specific capacity, cycle life, and rate performance in coin half-cells; also used for system compatibility tests in coin full cells.

2.2 Double-Sided Electrodes (NFPP-D01–D04): A Prelude to Pouch Cell Industrialization

Double-sided electrodes are designed with high loading and high compaction density to simulate mass production requirements for pouch cells:

• Parameter Adaptability: Double-sided areal density ranges from 24–40 mg/cm², current collector density from 3.3–3.63 mg/cm², and compaction density up to 2.35 g/cm³. All utilize wet coating to ensure uniformity, closely mimicking industrial pouch cell electrode parameters.
• Application Scenarios: Ideal for validating energy density, long-term cycling stability, and thermal safety in pouch cells (e.g., D03’s 2.35 g/cm³ compaction enhances volumetric energy density; D02’s 40 mg/cm² loading tests structural stability under high loads).

3. Atomfair Customization Services: Adjustable Parameters, Expandable Scenarios

Based on the above parameter matrix, Atomfair offers full-range customization to help customers push the boundaries of R&D:

• Material Selection: Choose from a variety of mature commercial materials from leading suppliers.
• Parameter Tuning: Adjust areal density, active material ratio, compaction density, and current collector specifications.
• Process Customization: Switch between dry and wet processes for single-sided electrodes; design asymmetric double-sided coatings (e.g., different loadings per side to match cathode/anode capacity ratios).
• Scenario Extension: Customize electrode dimensions (width, length) to fit cylindrical or prismatic cell formats beyond coin and pouch cells.

4. Collaboration Benefits: Precision Matching, Accelerated R&D

Choosing Atomfair’s customized NFPP electrodes enables:

• Shorter R&D Cycles: Precise parameter-scenario matching reduces repetitive validation, cutting the material-to-pouch cell verification timeline by 20–30%.
• Cost Control: Lock in production-ready parameters early in small-batch R&D, minimizing process transition costs from lab to production line.
• Competitive Edge: Tailored electrode solutions help build differentiated technical advantages in NFPP material applications.
