Product Description, Recommendations
1, vacuum storage or glove box with self-sealing bag 2 layer packaging, especially high nickel, sodium cathode materials, improper storage will lead to increased battery internal resistance
2. the pole piece is not rolled, and the pole piece needs to be rolled according to the recommended compaction density
3. The surface density of the coating shall be determined according to the actual weighing results. The surface density of the coating does not include the current collector.
4. actually weigh and calculate the mass of active substance (mg)= (tablet weight mg-current collector surface density mg/cm2 * tablet area cm2)* proportion of active substance
5. theoretical amount of active substance (mg)= coating surface density mg/cm2 * active substance ratio * wafer area cm2
6. theoretical surface capacity mAh/cm2 = coating surface density mg/cm2 * active substance ratio * g capacity mAh/g ÷ 1000
7. when calculating the gram capacity, it is calculated according to the amount of active substance actually weighed. due to the tolerance of coating surface density, the actual weighing shall prevail
8. creases: single-sided pole pieces are easy to roll after rolling, and flat packing may cause creases
