The dry pouch cell is moisture-sensitive and must be stored in a dry, inert atmosphere (≤0.1 ppm H2O) to prevent degradation of the electrode stack. Electrolyte filling and cell activation must be performed in a controlled environment to avoid contamination and ensure interfacial integrity.
- Environmental Storage: Store sealed pouches at room temperature in an argon-filled glovebox or dry room with dew point below -40°C.
- Handling Precautions: Avoid bending or puncturing the pouch laminate to maintain vacuum integrity and prevent short circuits.
- Electrolyte Compatibility: Use only anhydrous, battery-grade electrolytes with verified stability against SiC composite anodes and high-nickel NMC cathodes.
- Pre-Filling Conditioning: Pre-dry the dry cell under vacuum at 60°C for 12 hours to remove adsorbed moisture before electrolyte introduction.
Activate the electrolyte-free pouch cell by filling, sealing, and conditioning in a controlled atmosphere to establish baseline performance. Follow these steps to avoid moisture ingress and electrode damage.
Required Equipment: Argon-filled glovebox (H2O < 0.1 ppm, O2 < 0.1 ppm), Vacuum oven capable of 60°C, Electrolyte dosing syringe with septum port, Pouch sealer (heat sealer with adjustable temperature and pressure)
- Dry the pouch cell
Transfer the dry pouch cell to a vacuum oven and heat at 60°C under dynamic vacuum for 12 hours to remove residual moisture. - Fill with electrolyte
Inject the pre-determined volume of anhydrous electrolyte through the pouch tab port using a syringe within the glovebox atmosphere. - Seal the pouch
After filling without delay, heat-seal the open edge of the pouch at 190°C for 3 seconds while maintaining gentle pressure to ensure hermetic closure. - Rest and condition
Allow the sealed cell to rest in the glovebox undisturbed for at least 24 hours to ensure complete electrolyte wetting of the electrode stack.
How does the specific capacity mismatch between the Ni90 cathode (205 mAh/g) and the SiC anode (1600 mAh/g) affect the cell design?
The cell uses an NP ratio of 1.09 to ensure the anode’s total capacity slightly exceeds the cathode’s, preventing lithium plating during charging. This ratio is achieved by balancing the coating areal densities: 30 mg/cm² for the cathode and 4.5 mg/cm² for the anode, despite the sevenfold difference in specific capacity.
Can the ATOMFAIR Ni90 SiC dry pouch cell be tested directly on a cycler without injecting electrolyte?
No, this is an electrolyte-free platform and must be filled with a liquid or solid-state electrolyte before any electrochemical testing. The 12 µm PE separator with 2 µm ceramic coating is compatible with both liquid and solid electrolyte integration, but the dry core itself cannot conduct ions without an added electrolyte phase.
What are the required storage conditions for the dry pouch cell before electrolyte filling?
The cell must be stored in a dry, inert atmosphere—typically an argon-filled glovebox—to prevent moisture adsorption by the highly active electrodes (97.2% cathode and 90.3% anode active material). The dry cell has no internal short circuit risk, but ambient exposure can degrade the SiC anode and Ni90 cathode before use.
The ATOMFAIR Ni90 Silicon Carbon 5Ah Dry Pouch Cell is an electrolyte-free platform enabling customized solid-state electrolyte evaluation with a high-capacity SiC anode and high-nickel cathode stack. Its dry configuration demands careful electrolyte filling and sealing, but provides baseline control for interfacial kinetic studies.
Positive
- Ultra-high specific capacity SiC anode: The SiC anode delivers 1600 mAh/g specific capacity, enabling high energy density cell designs for advanced testing.
- Dry pouch design enables tailored electrolyte studies: As an electrolyte-free platform, it allows laboratories to screen custom liquid or solid electrolyte formulations while isolating interfacial kinetic behavior.
Trade-offs
- Requires electrolyte filling and vacuum sealing: The pouch cell is supplied unfilled, necessitating electrolyte injection and vacuum sealing in a controlled environment before electrochemical testing.
