This product, the NCM811 Electrode (SY33XX) from Canrd, is a single-sided, monocrystalline nickel-cobalt-manganese cathode sheet designed for advanced battery research and custom cell assembly. It features a high active material loading of 94.5% on aluminum foil, with a coating surface density of 9.20 mg/cm² and an areal capacity of 1.63 mAh/cm², delivering a specific capacity of 188 mAh/g when tested between 3.00–4.30 V at 0.1C. To ensure optimal performance, the electrode is recommended for use with Canrd’s KLD-1230C electrolyte and specific test protocols. Offered in both rolled and unrolled versions, the unrolled electrode requires post-processing by the user to achieve a compacted density between 2.50–3.35 g/cc. It is compatible with Canrd’s SM02XX, LT01XX, and SC02XX anodes for full-cell configuration. Proper handling includes vacuum baking before use, with a six-month shelf life when vacuum-sealed.

Because it is a single-sided electrode, there will be a roll-up situation 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.

Usage recommendations	1. If the electrode sheet is not rolled, it generally needs to be rolled before punching and baking (the compaction density can be referenced from the minimum value in the "Compaction Density" column of this table); 2. Baking conditions: 85-105℃ for 4 hours (if vacuum baking, it needs to be ventilated twice); 3. The areal density needs to be determined according to the actual weight of each small disc.

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 areal 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 SM0205, LT0101, SC0101 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.
