This electrode sheet is based on copper foil coated with Si-C material on a single side and is used as the cathode of Li-Ion battery – 5 sheets/pack
Because it is a single-sided pole sheet, curling may occur after calendering. The sheets were calendered in a controlled manner so curling does not happen. Calendering is strongly suggested at the customer’s site to improve the packing density, electronic conductivity, and binding of electrode materials.
- Un-calendered electrode needs to be calendered at the customer’s site before use.
- The areal density should be determined according to the actual weighing results.
- The electrode needs to be dried in a vacuum at 105℃ for 4h before being transferred into a glovebox.
- This positive sheet can be matched with our cathode sheets.
- The coating areal density does not include the copper current collector.
- Theoretical areal capacity by mAh/cm2 = coating areal density by mg/cm2 * Proportion of active loading * specific capacity by mAh/g
- The theoretical active loading (mg) = coating areal density by mg/cm2 * proportion of active loading * small disc area by cm2
