– Double-Sided Areal Density: 48 mg/cm²
– Compaction Density: 3.30 g/cm³
– Cathode/Anode Material Type: NCM-Cu (T18 model)

Structural Dimensions:
– Thickness (T): ~5 mm
– Width (W, incl. gas bag): 130 mm
– Length (L): 140 mm
– Top Edge Width (E): 5 mm
– Tab Center Distance (A): 24 mm
– Tab Width (B): 8 mm

Testing & Performance Reference:
– Recommended Voltage Range: 3.0 V – 4.4 V
– Recommended Electrolyte Injection: 3 g/Ah
– Recommended Electrolyte Type: Ternary (NCM) Electrolyte
– Internal Resistance (Post-injection): < 10 mOhm – Cycle Limit: Recommended for no more than 10 charge/discharge cycles Operational Process Reference: 1. Injection: Complete electrolyte injection in a glovebox according to reference tables. 2. Resting: Standing with gas bag at ambient temperature for >= 24 hours.
3. Activation: At 25°C, perform 0.1C constant current/constant voltage (CC/CV) charge, then 0.5C constant current discharge to 3.0 V (1 cycle).
4. Testing: Set specific rates or cycle steps for evaluation in an explosion-proof cabinet.
