Atomfair NVP Electrodes: Unlocking Scenario-Specific Keys to Sodium Battery R&D with a Precision Parameter Matrix

In the industrialization of sodium-ion batteries (SIBs), sodium vanadium phosphate (NVP) has emerged as a promising cathode material due to its long cycle stability and rapid ion conductivity. The electrode acts as the crucial “bridge” translating material properties into battery performance, and whether its parameters align with R&D scenarios directly impacts the efficiency of sodium battery technology iteration. Atomfair’s NVP electrode series, featuring multi-gradient parameter combinations and single/double-sided scenario-based designs, provides “scenario-precise” electrode solutions for the entire workflow—from lab-scale material research to industrial battery validation.

1. Core Parameters of NVP Electrodes: Multi-Dimensional Variations for Diverse R&D Needs

Atomfair’s NVP electrodes are built around a differentiated matrix of parameters—including areal density, active material ratio, and process type—to cover scenarios from basic research to pre-production validation:

Product Name	Code	Areal Density	Single/Double-Sided	Current Collector Areal Density	Active Material Ratio	Compaction Density	Coating Process
NVP Electrode	NVP-S01	5 mg/cm²	Single-sided	3.63 mg/cm²	93.50%	1.5 g/cm³	Wet Process
	NVP-S02	10 mg/cm²	Single-sided	3.63 mg/cm²	93.50%	1.5 g/cm³	Wet Process
	NVP-S03	20 mg/cm²	Single-sided	4.2 mg/cm²	94.50%	1.3 g/cm³	Dry Process
	NVP-S04	29.1 mg/cm²	Single-sided	4.2 mg/cm²	94.50%	1.3 g/cm³	Dry Process
	NVP-D01	20 mg/cm²	Double-sided	3.63 mg/cm²	93.50%	1.8 g/cm³	Wet Process
	NVP-D02	40 mg/cm²	Double-sided	4.2 mg/cm²	94.50%	1.3 g/cm³	Dry Process
	NVP-D03	58.2 mg/cm²	Double-sided	4.2 mg/cm²	94.50%	1.3 g/cm³	Dry Process

2. Scenario-Optimized Electrode Design: Single-Sided Focuses on Material Essence, Double-Sided Tackles Production Challenges

2.1 Single-Sided Electrodes (NVP-S01–S04): The Laboratory‘s “Material Characterisation Lens”

Single-sided electrodes, with gradient combinations of process type and active material ratio, serve as a core tool for revealing the intrinsic properties of NVP:

• Parameter Highlights: Areal density spans from 5 mg/cm² (low loading, focusing on specific capacity) to 29.1 mg/cm² (testing high-load stability); includes both wet (S01/S02) and dry (S03/S04) processes for comparing performance under different fabrication methods.
• Application Scenarios: Ideal for “material-level testing” in coin half-cells (e.g., specific capacity, cycle life, rate capability) and “system-level screening” in coin full-cells (e.g., electrode matching, electrolyte compatibility), providing precise data for NVP modification and doping studies.

2.2 Double-Sided Electrodes (NVP-D01–D03): The Industrial “High-Load Performance Proving Ground”

Designed with ultra-high areal density and process-specific optimizations, double-sided electrodes target the core industrial requirement of high energy density:

• Parameter Highlights: Total double-sided areal density reaches up to 58.2 mg/cm² (NVP-D03), approaching “limit loading” of production electrodes; current collector density is upgraded (4.2 mg/cm²) to support high loads; compaction density is tailored (e.g., D01 at 1.8 g/cm³ enhances volumetric energy density).
• Application Scenarios: Suitable for “industrial-level validation” in pouch or cylindrical cells, testing structural stability and cycle life under high loading (e.g., long-term cycling of D03 at 58.2 mg/cm²). Electrodes like D01 also help validate gains in volumetric energy density, informing production process optimization.

3. Customization Services: Flexible Extension from Standard Parameters to Unique Needs

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

• Material Compatibility: Electrodes can be tailored to customer-developed NVP materials (e.g., doped, morphology-modified), ensuring compatibility and accelerating material iteration.
• Parameter Tuning: Fine-tune areal density, active material ratio, compaction density, and current collector specs—e.g., reduce compaction density and increase porosity for high-rate sodium batteries.
• Process Customization: Option to switch between wet and dry processes.
• Scenario Expansion: Custom solutions available for specialized R&D directions, such as “high-rate NVP electrodes” with optimized conductive networks.

4. Collaboration Benefits: Precision and Efficiency to Accelerate Sodium Battery Commercialization

Choosing Atomfair NVP electrodes delivers three key value enhancements:
