This research-grade electrode sheet features a single-sided LMR coating at 6 mg/cm² on a carbon-coated aluminum foil substrate. The material delivers 300 mAh/g capacity with 94.7% active material ratio for laboratory battery testing.
- Coating Composition: The active coating comprises LMR material with a 94.7% active material ratio.
- Substrate: The substrate is a carbon-coated aluminum foil with an areal density of 3.20 mg/cm² and thickness of 12 μm.
- Coating Density: The single-sided coating has an areal density of 6 mg/cm² applied via a wet process.
- Coating Area: The coating area measures 150 x 70 mm on a substrate of 180 x 70 mm.
- Nominal Capacity: The material exhibits a nominal capacity of 300 mAh/g.
What performance trade-off does the carbon-coated aluminum current collector introduce for the LMR-S04 cathode compared to uncoated aluminum?
The carbon-coated aluminum current collector minimizes boundary contact resistance and electrode polarization, improving rate capability and reducing voltage loss. However, it adds an areal density of 3.20 mg/cm² with a 12 μm thickness, slightly increasing the electrode’s total weight and inactive mass fraction relative to an uncoated collector.
What are the dimensional constraints for integrating the LMR-S04 cathode into standard coin cell assemblies or pouch cell prototypes?
The standard substrate size is 180×70 mm with a single-sided coating area of 150×70 mm, so electrodes must be punched to fit smaller cell formats. Custom adaptations for coating thickness, coating width, and foil dimensions are fully supported, allowing researchers to specify tailored substrate geometries without changing the active material loading.
What drying protocol is mandatory before the LMR-S04 can be used in cell assembly, and why is this step critical?
The standard electrode preparation protocol requires vacuum baking at 100°C for 12 hours to remove residual moisture. This step is critical because moisture in LMR cathodes can trigger decomposition of LiPF₆ salts, generate HF, and cause gas evolution, compromising the electrochemical performance and safety of the assembled cell.
This LMR-S04 electrode sheet offers a 94.7%-active-material loading with 300 mAh/g capacity on a carbon-coated aluminum substrate, precision wet-coated at 6 mg/cm² single-side. It is optimized for high-capacity Li-ion battery R&D but requires a 12-hour vacuum bake at 100°C before use and is limited to single-sided cell architectures.
Positive
- High active material loading: With 94.7% active material, the electrode achieves a target capacity of 300 mAh/g, enabling high-energy-density test cells.
- Uniform wet coating deposition: Precision wet processing ensures consistent 6 mg/cm² coating density and film thickness, critical for reproducible electrochemical measurements.
Trade-offs
- Mandatory vacuum baking step: The electrode requires a 12-hour vacuum bake at 100°C before use, adding a scheduled processing step and oven infrastructure.
- Single-sided coating limitation: The single-sided architecture restricts use to cell designs requiring only one active face, excluding symmetrical or bipolar configurations without additional handling.
