1: Do not put it in fire or use it near a heat source! ! ! 2: Do not use metal to directly connect the positive and negative poles of the output. 3: Do not use it beyond the battery temperature range. 4: Do not clamp the battery forcefully. 5: Use a special charger or charge correctly. 6: When the battery is left out, please recharge it every three months. And place it according to the storage temperature
The coating process of lithium batteries is dangerous. Lithium-ion batteries are absolutely harmful to the human body. The most harmful thing is the electrolyte solution. The electrolyte is a volatile organic liquid and is obviously corrosive. Prolonged inhalation of volatile gases may cause damage to the respiratory tract.
If you manufacture battery cells, the contents inside the battery cellsis harmful to the human body. It is not recommended to go there. You must wear a gas mask or face mask when you go there. work. I used to unknowingly open a bucket of stack ingredients, smoke it, and not be able to eat for a whole day. If you do PACK, it has virtually no impact on the body (some workstations must be exposed to organic solvents). ). It's harmful.
Remarks
Storage requirements: In an environment with a temperature of 20 ± 5 ℃ and humidity not exceeding 50%, corrosion of the aluminum foil by the Air and water vapor should be avoided during transportation.
This product is divided into two types, A and B. The main characteristics of each are: the appearance of type A is black, the conventional coating thickness is 4-8μm on both sides and the conductive performance is more remarkable; the appearance of type B is light grayr and the conventional coating thickness is 2-3 μm on both sides. Fewer welding layers can be done in the cladding area and the cladding machine can identify skip gaps.
Type B (gray) carbon coated aluminum sheet can be ultrasonic welded directly in the coating area. It is only suitable for soldering laminated battery tabs (up to 2-3 layers of pole pieces), but the power and time of ultrasound require fine tuning.
The heat dissipation of carbon layer is worse than that of aluminum foil, so the belt speed and baking temperature should be adjusted appropriately when coating.
This product can significantly improve the overall performance of lithium batteries and capacitors, but it cannot be used as the main factor to change some aspects of performance.battery performance, such as battery energy density, high and low temperature performance, high voltage, etc.
