　　6. Packaging and storage conditions

　　6.1. Packing method: Inner aluminum foil bag, vacuum packaging, outer carton, 25kg/box.

　　6.2. Requirements for stacking layers: carton packaging ≤ 3 layers.

　　6.3. Label style: the default Haili lithium battery shipping label, if the customer has special requirements, it can be implemented according to the label style provided by the customer.

　　6.4. Storage conditions: Keep sealed and avoid direct sunlight. The recommended storage temperature is 20±10°C and the humidity is ≤50%RH. The shelf life is 2 years. If the product exceeds the shelf life, it should be inspected by our company and re-evaluated whether it can be used normally.

　　6.5. Under the condition of unsealing, strictly control the storage humidity to ≤30%RH, and use it as soon as possible.

　　7. Precautions for transportation

　　When loading, do not place heavy objects on top of the cartons to prevent deformation of the cartons; prevent extrusion and sun and rain; use vehicles, trains, ships, planes and other vehicles for transportation.

　　8. Suggestions for processing and use

　　Positive electrode ratio: 95.5% to 97.0% of ternary material, 1.0% to 2.5% of conductive agent, and 2.0% to 2.5% of binder. It is recommended to use PVDF with a molecular weight greater than 1 million as the binder. If the binder is made by the suspension method, the dosage can be adjusted to 1.0% to 1.5%.

　　Suggested negative electrode excess ratio: 10% to 15%.

　　It is recommended to use compaction: 3.45～3.55g/cm3.
