This document outlines critical handling and storage requirements for the LiFePO4 coated cathode sheets. Adherence to these constraints prevents degradation and preserves electrochemical performance.
- Moisture Sensitivity: The electrodes must be kept in a tightly sealed package or processed exclusively within an anhydrous inert gas glovebox environment.
- Micro-Crack Prevention: Avoid micro-crack phase transformation by maintaining the inert atmosphere until cell thermal consolidation.
- Mechanical Handling: Pre-cut tabs eliminate mechanical handling damage during cutting, but careful handling is still required to avoid physical damage.
- Thermal Consolidation: Process the electrodes in a glovebox before any thermal consolidation step to preserve baseline electronic validation properties.
This procedure describes the proper handling and storage of the coated cathode sheets to maintain integrity. Follow these steps to avoid moisture exposure and mechanical damage.
Required Equipment: Anhydrous inert gas glovebox
- Inspect Package
Inspect the sealed package upon receipt for any visible damage or breach. - Transfer to Glovebox
Transfer the sealed package into an anhydrous inert gas glovebox without opening it. - Open and Store
Open the package only inside the glovebox and keep the sheets under inert atmosphere until use.
How does the 17.4 mg/cm² coating areal density affect rate capability and energy density?
The 17.4 mg/cm² coating areal density is designed to balance rate capability and capacity. According to the specifications, this loading is optimized for rapid ion diffusion on the ultra-lightweight 3.3 mg/cm² aluminum substrate, achieving <2% thickness variance. This yields a 160 mAh/g design capacity with 96.25% active material ratio for high-energy lithium-ion systems.
Is this cathode sheet compatible with both coin cell and pouch cell configurations?
Yes, the sheet dimensions of 120 × 140 mm with a 120 × 120 mm coated active area and a 20 mm bare foil tab are explicitly designed for coin cell and pouch cell assembly, as stated in the product overview. The pre-cut tab eliminates mechanical handling damage during cutting, making it suitable for both research-scale and pilot line development.
What storage and handling conditions are required to prevent degradation of the LiFePO4 coated foil?
To preserve baseline electronic validation properties and avoid micro-crack phase transformation, the product must be kept tightly sealed or processed exclusively within an anhydrous inert gas glovebox environment before cell thermal consolidation. This is specified in the important notice section to prevent degradation from moisture or oxygen exposure.
Single-side LiFePO4 coated aluminum foil cathode sheets with 96.25% active material ratio and 160 mAh/g design capacity, featuring precision coating with <2% thickness variance and pre-cut tabs for research-grade coin and pouch cell assembly.
Positive
- High Active Material Purity: 96.25% LiFePO4 active material ratio minimizes inert additives, maximizing theoretical capacity utilization for high-energy lithium-ion cells.
- Precision Coating Architecture: 17.4 mg/cm² coating loading on a 3.3 mg/cm² aluminum substrate achieves <2% thickness variance, ensuring consistent electrochemical performance across the electrode.
Trade-offs
- Strict Handling and Storage Requirements: To preserve baseline electronic validation properties and avoid micro-crack phase transformation, packages must be kept tightly sealed or processed exclusively within an anhydrous inert gas glovebox before cell thermal consolidation, requiring specialized laboratory infrastructure.
