Interpretation of lithium-ion battery pack assembly process and installation precautions

1. Lithium-ion battery pack assembly process objects/materials: positive electrode material, negative electrode material, barrier paper pace/essentials ①Pulping: use a special solvent and binder to separate and mix the powdered positive and negative active materials with high speed After stirring evenly, a slurry-like positive and negative material is made. ②Coating: Coat the prepared slurry evenly on the appearance of the metal foil, dry, and separate to make positive and negative pole pieces. ③Assembly: Put the positive electrode sheet-the barrier-the negative electrode sheet-the barrier from top to bottom, and wind it to form the battery pole core, and then through the process of injecting electrolyte and sealing to complete the battery assembly Process to make a product battery. ④Formation: Use special battery charging and discharging equipment to conduct charging and discharging tests on product batteries, and conduct testing for each battery, and screen out qualified product batteries before leaving the factory. Reminder: The process skills of lithium-ion battery pack assembly are very strict and huge. This is just a simple introduction! When everyone assembles lithium-ion battery packs, they must strictly follow the standard skills to produce and assemble, and there should be no slack. 2. Precautions for installation of lithium-ion battery pack  (1) All wires must be connected securely. The exposed copper wires must be restrained from touching each other (including staggered touching), which will easily damage the controller and display the protection of the lithium-ion battery protection board. Unlit environment. During the installation process, restrain the short circuit between the line and the line. (2) The expected light-on time during the wiring process will vary according to the time difference of the controller configuration. The large capacity of the factory lithium-ion battery is generally half-electric, and the light will be darker when it is first installed, which is a normal category. Lights up normally after 2-3 days of normal charging. (3) The installation time of lithium-ion battery packs is generally held in daylight, and it is not suitable to hold the installation at night. (4) In the use of batteries, it includes the protection of aluminum-plastic composite film, top sealing (edge u200bu200bsealing at the pole end), side sealing, and protection against machine impact and short circuit.
