Single-side coated electrode sheet with 10 mg/cm² active material loading on carbon-coated aluminum foil. Intended for sodium-ion battery research and development to evaluate electrochemical performance.
- Coating material: The coating material is sodium vanadium phosphate (NVP) with an active material ratio of 93.5%.
- Coating density: The coating density is 10 mg/cm² applied via a precise wet process.
- Coating area: Each sheet has a coating area of 152 by 100 mm.
- Substrate material: The substrate is carbon-coated aluminum foil with a thickness of 12 ±0.5 μm.
- Current collector areal density: The current collector areal density is 3.63 mg/cm².
What is the theoretical areal capacity of the NVP-S02 electrode given its coating density and specific capacity?
The theoretical areal capacity is approximately 1.1 mAh/cm², derived from the coating density of 10 mg/cm² and the specific capacity of 110 mAh/g. This calculation assumes full utilization of the active material at the stated capacity, which is typical for rate-independent testing in sodium-ion R&D.
How does the carbon-coated aluminum substrate in the NVP-S02 electrode affect compatibility with electrolyte solvents and cell assembly?
The carbon-coated aluminum foil current collector (12 μm thickness, 3.63 mg/cm² areal density) provides enhanced adhesion for the NVP coating and reduces electronic contact resistance, improving compatibility with standard carbonate-based electrolytes used in sodium-ion research. This configuration is designed for single-sided coating, enabling direct use in coin or pouch cell assembly without additional substrate modifications.
What are the recommended vacuum baking conditions for the NVP-S02 electrode before cell assembly?
The electrode sheet must be vacuum baked at 100°C for 12 hours to remove residual moisture and solvents from the wet coating process. This step is critical to prevent parasitic reactions and ensure reproducible electrochemical performance in sodium-ion battery tests.
This NVP-S02 electrode sheet delivers a high active material loading of 93.5% with a consistent 10 mg/cm² areal density via wet coating, enabling reproducible sodium-ion battery R&D. Its single-sided configuration and mandatory 12-hour vacuum baking at 100°C impose specific cell assembly and processing infrastructure requirements.
Positive
- High active material loading: With 93.5% active material ratio, the electrode maximizes capacity per unit mass, improving cell-level energy density for sodium-ion battery testing.
- Precision wet coating process: The 10 mg/cm² coating via wet process ensures uniform areal loading across the 152×100 mm coated area, supporting consistent electrochemical evaluation.
Trade-offs
- Extended vacuum baking needed: The electrode requires 12 hours vacuum drying at 100°C before use, demanding a vacuum oven and adding processing time to experimental workflows.
- Single-sided coating limitation: Single-side coating restricts cell assembly to configurations using only one active face (e.g., half-cells), limiting design flexibility for full cells or bipolar stacks.
