LCO Cathode Electrode Sheet (Lithium Cobalt Oxide Electrode Sheet) Cathode Coating Aluminum Foil Coated with Lithium Cobalt Oxide (Single-Side/Double-Side)

Our LCO (Lithium Cobalt Oxide) Cathode Electrode Sheet is a high-performance core component for high-energy-density lithium-ion batteries, available as single-side or double-side coated layers on high-conductivity aluminum foil substrates. As a classic cathode material, LCO delivers exceptional theoretical capacity (up to 274 mAh/g) and outstanding voltage platform stability (≈3.7V nominal), enabling batteries to achieve compact designs and long runtime—ideal for scenarios requiring high energy density.

1. Electrode Sheet Cutting
   Equipment: MSK-T10 sheet cutter
   Recommended size for coin cell electrode sheets: 12mm/14mm in diameter
2. Electrode Sheet Weighing
   Equipment: Sartorius BCE series balance
   Formula for active material calculation:
   Active material mass = [(Electrode sheet mass (mg) - Disc area (cm²) * Current collector areal density (mg/cm²))] * Active material proportion
3. Electrode Sheet Drying
   Equipment: DZF-6050(53L) vacuum drying oven
   Temperature: 60–80°C
   Time: 2–4 hours
4. Electrode Sheet Assembly
   Equipment: VGB-10-I single-station glove box, MSK-110 small hydraulic coin cell sealing machine
   Recommended battery assembly sequence:
   Negative case → Lithium sheet → Electrolyte → Separator → Electrolyte → Electrode sheet → Gasket → Spring sheet → Positive case
5. Battery Testing
   Equipment: 5V10mA8 channel battery tester
   Steps: Calculate the active material mass, then input the corresponding current and voltage range.
   Current calculation:
   0.1C = 1C = (Active material mass (mg) * 0.001 * Nominal specific capacity (mAh/g)) * 0.1
