    Battery pack assembly line including the process of battery cell tester-battery paper pasting machine-battery cell sorting machine-CCD tester- battery pack spot welding machine- battery pack BMS tester-battery pack integrated tester-PVC shrinking machine-code printing machine-Battery pack aging machine. Aging detection is generally the last step before the battery pack is completed，then why do lithium battery packs need aging test ？     One is to make the electrolyte infiltration better, which is conducive to the stability of the performance of the lithium battery pack;     Second, the active materials in the positive and negative materials can accelerate the progress of some side effects after aging, such as gas production and electrolyte decomposition, so that the electrochemical performance of the lithium battery pack can quickly stabilize;     The third is to screen the consistency of lithium battery packs after a period of aging. After the formation, the voltage of the battery cell is unstable, and the measured value will deviate from the actual value. The voltage and internal resistance of the battery cell after aging are more stable, which is convenient for screening batteries with high consistency.

The Glove Box is an operating device that works in the box with high purity inert gas. Widely used in ultra-pure environments without water, oxygen and dust，such as lithium ion batteries and materials etc. The solution to the safety problems of lithium-ion batteries is mainly in the test and production process. Since lithium metal has extremely high oxidizing properties to water vapor and oxygen, the basic conditions and equipment requirements for the development of lithium ion polymer batteries are very strict. Whether in the previous test or assembly, the concentration of water and oxygen must be It is carried out in a very low environment. In the manufacturing process of lithium batteries, water is the biggest enemy. Water may decompose the electrolyte and affect the performance of the battery. Water will also react with the cathode and anode materials, so when the battery is injected, it must be carried out in a glove box with a very low moisture content. After the injection is completed, it can be taken out of the glove box. ACEY New Energy provides professional Glove Chamber. Our Lab2000 glove box is a high-performance, high-quality closed cycle working system that automatically absorbs water and oxygen molecules and purifies the working environment.

1. Definition of cylindrical lithium battery Cylindrical lithium battery is a kind of lithium ion battery. Its shape is cylindrical, so it is called cylindrical lithium battery. Cylindrical lithium battery is divided into lithium cobalt oxide (LiCoO2), lithium manganate (LiMn2O4), Lithium nickel cobalt manganate (LiNiMnCoO2 or NMC), lithium nickel cobalt aluminate (LiNiCoAlO2 or NCA), lithium iron phosphate (LiFePO4) and lithium titanate (Li4Ti5O12). There are many types of cylindrical lithium batteries, the common ones are 14500, 14650, 18500, 18650, 21700, 26650, 32650, etc., which are widely used in various equipment. 2. Cylindrical lithium battery structure The structure of a typical cylindrical battery includes: shell, cap, positive electrode, negative electrode, separator, electrolyte, PTC element, gasket, safety valve, etc. Generally, the battery case is the negative electrode of the battery, the cap is the positive electrode of the battery, and the battery case is made of nickel-plated steel plate. 3. The advantages of cylindrical lithium batteries The production process is mature, the PACK cost is low, the battery product yield rate is high, and the heat dissipation performance is good. Cylindrical batteries have formed a series of internationally unified standard specifications and models with mature technology and suitable for continuous mass production. The specific surface area of the cylinder is large, and the heat dissipation effect is good. Cylindrical batteries are generally sealed batteries, and there are no maintenance problems during use. The battery shell has high pressure resistance, and there will be no phenomena such as square, flexible packaging battery swelling during use. 4.Cylindrical lithium battery cells, modules and battery packs 1. Cylindrical lithium battery： The battery cell is the smallest unit of a lithium battery pack and also an electric energy storage unit. It must have a higher energy density to store as much electric energy as possible to make the equipment work longer. In addition, the life of the lithium battery is also the most critical factor, any damage to a battery will cause damage to the entire battery pack.  2. Lithium battery module： When multiple cells are encapsulated by the same housing frame and communicate with the outside through a unified boundary, this constitutes a module.  3. Lithium battery pack When several modules are jointly controlled or managed by the BMS and thermal management system, this unified whole is called a lithium battery pack. Cylindrical lithium battery safety test items In order to ensure the safety of cylindrical lithium batteries, domestic and foreign institutions have formulated various safety testing standards for cylindrical lithium batteries. General testing standards generally divide safety testing items into the following four categories:  Electrical test: overcharge, overdischarge, external short circuit, forced discharge, etc.  Mechanical...
