III. Application Recommendations
-
Application Scenario: Cathode of sodium-ion batteries.
-
Electrode Compaction: 2.30–2.50 g/cm³, suitable for organic slurry system.
-
Moisture Protection Key Point: The material is easy to absorb moisture, and its performance will decrease irreversibly after absorbing moisture; strictly control moisture during sampling/use, and vacuum seal the remaining material in a timely manner.
-
Battery Cell Environment Requirements:
-
Slurrying/coating humidity < 10%
-
Battery cell assembly humidity < 5%
-
Liquid injection dew point < -45℃
-
Moisture content of positive electrode sheet before liquid injection < 400 ppm
