Electrode Calculation Guide & Example
To ensure precision in your electrochemical analysis, use the following formulas. For high-fidelity research, actual weighing should take precedence over theoretical averages.
The Calculation Algorithm
- Current Collector Weight:
- Formula: Current Collector Areal Density (mg/cm²) × Wafer Area (cm²)
- Example: 3.63 mg/cm² × 0.7854 cm² ≈ 2.851 mg
- Coating Weight of the Sample:
- Formula: Total Wafer Weight (mg) – Current Collector Weight (mg)
- Example: 10.68 mg – 2.851 mg = 7.829 mg
- Active Material Weight:
- Formula: Coating Weight (mg) × Active Material Ratio (%)
- Example: 7.829 mg × 0.945 ≈ 7.398 mg
- Actual Areal Density:
- Formula: Active Material Weight (mg) ÷ Wafer Area (cm²)
Expert Note: As the original manufacturer, we provide these calculation frameworks to help researchers eliminate variables in their testing. The specific capacity should always be calculated using the actual active material mass derived from your punched electrode weight to account for inherent micro-variations in high-loading coatings.
User Guide: Identifying Front vs. Back
When working with single-sided electrode sheets, identify the active coating side under natural or soft artificial light:
- Front Side (Coated): Appears dark and matte. This is the active Sodium Vanadium Phosphate layer.
- Back Side (Uncoated): Appears lighter and metallic. This is the exposed aluminum substrate.
Research Applications
This NVP electrode sheet is specifically optimized for:
- Sodium-ion Battery (SIB) R&D: Baseline testing for new electrolyte formulations.
- High-Loading Studies: Evaluating the kinetics of thick-electrode architectures.
- Dry Electrode Benchmarking: Comparing dry-process electrochemical performance against wet-coated benchmarks.
FAQ
What is the recommended vacuum baking procedure for NVP electrodes?
To ensure complete moisture removal, we recommend vacuum baking the sheets at 100°C for 12 hours prior to cell assembly.
