Products Description
Because it is a single-sided electrode, there will be a curl after rolling, so the shipped roller-pressed electrode has controlled and compacted to ensure that the electrode is not rolled;
Rolling can improve the compacting density of the electrode, improve the electronic conductivity of the electrode, and improve the bonding.
1. The electrode should be rolled before use, and the customer needs to arrange the rolling pressure by himself to purchase the electrode that has not been rolled;
2. The surface density shall be determined according to the actual weighing results;
3. Before putting it in the glove box, the punched electrode needs to be vacuum baked at a temperature of 105 °C for 4 hours;
4. This electrode can be matched with our YT0101 anode electrode; 5. The density of the coating surface does not include the current collector;
6. Theoretical surface capacity mAh/cm2 = coating surface density mg/cm2 * proportion of active substance * gram capacity mAh/g÷1000;
7. The amount of theoretical active substance (mg) = coating surface density mg/cm2 * proportion of active substance * small disc area cm2;
8. The actual weighing calculates the amount of active substance (mg) = (weight of small disc mg – current collector surface density mg/cm2 * small disc area cm2) * proportion of active substance, and calculates the gram capacity according to the amount of active substance actually weighed, due to the tolerance of the density of the coating surface, the actual weighing shall prevail.
