What are the requirements for the packaging of the customer's battery?

1. For some customers who complained about low capacity, add 2 minutes of capacity; 2. For Tianyu, the customer must control the lower limit of the size; 3. When the model battery is changed, whether to clean the entire strip to prevent mixing; 4. Check out Whether the defective product is packed in a red turnover box and whether it is clearly marked; 5. Whether the special requirements on the order have been understood and implemented by the employees; 6. Whether the coding content is correct, and whether the coding direction and position are correct; 7. The pressure plate and rivets Whether there is glue on the surface; 8. Check whether the instrument is within the validity period to prevent the inaccurate instrument from being used online (for all stations). In the process of realizing energy conversion, the chemical power source must have two necessary conditions. One. The oxidation-reduction process performed on the two electrodes constituting the chemical power source must be carried out in two separate areas, which is different from the general oxidation-reduction process. reaction. 2. The electrons required for the redox reaction of the active material of the two electrodes must be transferred by the external circuit, which is different from the micro-battery reaction of the metal corrosion process. In order to meet the above conditions, any chemical power source is composed of the following four parts: 1. The core part of the electrode battery, which is composed of active materials and conductive framework. Active material refers to the material that participates in the flow reaction in the positive and negative electrodes. It is the source of electrical energy in the chemical power source and an important part that determines the basic characteristics of the chemical power source. The requirements for active materials are: 1) High electromotive force that composes the battery; 2) High electrochemical activity, that is, strong ability to react spontaneously; 3) Large weight ratio and volume ratio capacity; 4) Chemical stability in the electrolyte High performance; 5) High electronic conductivity; 6) Abundant resources and low price. 2. One of the important components of the electrolyte battery, it is responsible for transferring the charge between the positive and negative electrodes inside the battery, so there are some materials with high ionic conductivity. The requirements for the electrolyte are: 1) Strong stability, because the electrolyte is stored inside the battery for a long time, it must have stable chemical properties, so that the electrochemical reaction rate at the interface between the electrolyte and the active material during storage is small, so that the battery's self-discharge capacity The loss is reduced; 2) The specific conductivity is higher, and the ohmic voltage drop of the solution is small, so that the discharge characteristics of the battery can be improved. Regarding the solid electrolyte, it is required to have only ionic conductivity, not electronic conductivity. 3. The diaphragm is also called a spacer. Place between the two poles of the battery. The shape of the diaphragm includes film, sheet, rod and so on. Its purpose is to prevent direct contact between the positive and negative active materials, causing short circuits inside the battery.
