How to Read This Configuration
Compare side, loading, process, and collector when selecting an LMR sheet for a controlled experiment.
- Areal loading: 30 mg/cm2. Use this value as the coating-mass basis when comparing electrode configurations.
- Active material ratio: 96% is the listed active-material fraction of the coating formulation. The actual active mass still depends on the punched electrode mass.

Drying and Handling
Before cell assembly, dry the electrode sheet at 90-100 C for 12-24 hours. Use a clean, dry handling environment after drying.
Avoid bending, scratching, or contaminating the coated surface during cutting, punching, transfer, and stacking.

The material is moisture-sensitive and must be dried under vacuum before cell assembly. The dry-processed coating requires careful handling to avoid mechanical damage or contamination.
- Pre-Assembly Drying: Standard preparation protocol requires 12 hours of vacuum baking at 100°C before formal cell assembly to remove environmental moisture layers.
- Moisture Protection: The sheets are vacuum-sealed to maintain low moisture content, and exposure to ambient air should be minimized until thermal treatment.
What is the advantage of the dry process for the LMR-S05 cathode electrode sheet, and how does it affect the active material ratio and mechanical integrity?
The dry process enables a 96.00% active material ratio by using high dry shear binder networks that provide robust mechanical binder structures and flawless single-sided film uniformity without solvent residues. This eliminates solvent-related issues and ensures consistent performance across the 5-sheet pack.
How does the carbon-coated aluminum foil substrate in the LMR-S05 electrode sheet influence contact polarization and cycle life?
The carbon-coated aluminum foil current collector reduces contact polarization, especially under the dense 30 mg/cm² coating load, which helps extend test cell cycling metrics. The substrate has an areal density of 4.4 mg/cm² and a thickness of 12 + 0.5 + 0.5 μm, providing a stable base for the 300 mAh/g capacity design.
What pre-treatment is required for the dry-processed LMR-S05 electrode sheets before cell assembly?
The sheets require vacuum baking at 100°C for 12 hours to remove environmental moisture layers before formal cell assembly. The product is vacuum-sealed in packs of 5 sheets to maintain batch constants, and proper handling is critical due to the dry-processed nature.
Atomfair LMR-S05 is a single-side coated lithium-rich manganese-based cathode sheet with 30 mg/cm² loading, 96% active material, and 300 mAh/g capacity, designed for research-grade battery testing. The dry process and carbon-coated aluminum collector enhance uniformity and reduce polarization, but the material requires vacuum baking prior to assembly.
Positive
- High active material ratio and capacity: 96.00% active material ratio and 300 mAh/g capacity provide high energy density for advanced electrochemical testing and material validation.
- Dry process with carbon-modified collector: Dry process ensures uniform coating without solvent residues; carbon-coated aluminum foil reduces contact polarization under dense loads.
Trade-offs
- Mandatory vacuum baking protocol: Requires 12 hours vacuum baking at 100°C before cell assembly to remove moisture, adding preparation time and infrastructure demands.
- Moisture-sensitive dry process electrode: Dry processed cathode sheets are highly susceptible to environmental moisture, necessitating vacuum-sealed packaging and careful handling to maintain performance.
