Let me introduce you to the type of automated production line in Nichwell.

With the development of science and technology, lithium batteries are widely used in many fields such as electric vehicles, electric bicycles, electric motorcycles, electric vehicles, military equipment, aerospace, notebook computers, and mobile power supplies. The large-capacity lithium-ion battery currently developed has been used in electric vehicles and is expected to become one of the main power sources for electric vehicles in the 21st century, and will be used in artificial satellites, aerospace and energy storage.

With the shortage of energy in the world and the pressure of global environmental protection, lithium batteries are being widely used in the electric vehicle industry. Because the lithium ion battery needs to inject electrolyte into the battery during the production process, and then discharge the gas inside the battery through the formation process. This puts higher requirements on the sealing performance of the battery after liquid injection, the smooth exhaust during the formation process and the sealing performance after the completion of the formation.

There are many disadvantages in the operation process: seal failure is prone to occur, the operation process is cumbersome, and the cost is high. In order to be able to solve the problems in the existing technology, the lithium battery automated production line produced by the latest technology in Nichwell glove box  can ensure the liquid injection and exhaust, and also effectively prevent the external moisture from entering the battery and operate simple.

Production of Lithium-Ion Battery Equipment

The existing lithium ion battery injection method and equipment are relatively complete, but due to the relatively large injection volume of the lithium ion power battery, the existing injection equipment can no longer meet the production needs. The injection of the lithium ion power battery is the battery preparation process A very important process in the current, and the current lithium ion battery injection equipment uses a simple composed of electrolyte irrigation, storage tank, liquid injection valve, injection pump, injection cylinder, injection needle and vacuum pump. The device needs to open the valve manually, and only one battery can be injected at a time. The injection efficiency is low and the operation is inconvenient.

In order to solve the problem that the existing lithium ion power battery liquid injection equipment needs to manually open the valve, only one battery can be injected at a time, the liquid injection efficiency is low, and the operation is inconvenient. Nichwell provides an automatic production line for lithium batteries. The automatic production line for lithium batteries can realize automatic code scanning-injection-weighing-replenishment-sealing operation in the super-purified glove box, which can complete the injection of multiple batteries in one operation. Liquid, easy production operation, high injection efficiency.

Lithiumbattery automatic production line features

Features:

This production line is a fully automated production line for round solid-state batteries. The whole process is completed in the glove box, ensuring that the entire process is produced in an oxygen-free and water-free environment, ensuring the quality of the product. In order to ensure that the positive electrode material, solid electrolyte, and negative electrode material are accurately injected, the process characteristics are as follows:

In recent years, with the rise of lithium battery manufacturing industry, the participation of many lithium battery manufacturing companies has made the domestic lithium battery market uneven.Now the lithium battery industry has entered a stage of rapid development, but the current equipment and process conditions all restrict us The rapid development of many companies in the industry, how to make lithium batteries small and durable, high energy storage density, and even beautiful, etc., are all problems in front of us! Equipment is one of the important aspects, introduced here Let's take a look at the key role of Nichwell's glove box in the production of lithium batteries.

With the promotion of new energy vehicles, environmentally friendly electric vehicles have become a new trend of energy saving and emission reduction for automobiles. Because of its high efficiency, safety and reliability, lithium ion batteries are currently the best comprehensive green batteries. The application fields of lithium-ion batteries will become more and more extensive. Lithium-ion batteries are composed of three parts: a battery cell, a protection circuit, and a case. The shell is divided into a shell and a cover. Insulation seals, gaskets, etc. need to be provided on the battery cover. Traditional battery covers are assembled manually by workers, and the cover marking, laser welding, CCD detection, cover film, and film bending are required. Each production process, such as cleaning fixtures, is equipped with a corresponding production line, which results in greater labor intensity, higher production costs, low production efficiency, and low assembly accuracy, which cannot meet the needs of large-scale battery production.
In order to solve the existing technical needs of manual assembly by workers, Etelux resulted in higher production costs, lower production efficiency and lower assembly accuracy. And provide a lithium battery automated productionline.

With the worldwide energy crisis and climate warming, a new energy model is urgently needed in the field of transportation. Lithium-ion batteries have attracted widespread attention in the field of transportation due to their environmental protection and high energy output. At present, relevant industries around the world have conducted extensive research on the application of lithium ion batteries in this field.

Lithium-ion batteries have the advantages of high working voltage, high specific energy, long cycle life, and no environmental pollution. They are not only widely used in mobile communication equipment and portable electronic equipment, but also widely used in electric vehicles, electric bicycles, and power tools. In terms of large and medium-sized electric equipment, it is the main development direction of major battery manufacturers. At present, lithium-ion battery packs have been widely used in various fields, especially in the field of electric vehicles.

Lithiumbattery refers to a battery containing lithium (including metallic lithium, lithium alloy and lithium ion, lithium polymer) in the electrochemical system. Lithium batteries can be roughly divided into two categories: lithium metal batteries and lithium ion batteries. Lithium-ion batteries do not contain metallic lithium and are rechargeable. In the past, lithium batteries have not been used for a long time because of their very active chemical properties, high requirements for processing, storage, use, and environment. With the development of modern science, lithium batteries have now become mainstream, and are widely used in my country's new energy vehicles, grid energy storage, special vehicles, and communication base stations.

When the lithium ion battery is in normal operation, the negative electrode terminal drawn from the negative electrode current collector and the positive electrode terminal drawn from the positive electrode current collector form an electronic path with the external circuit, and the lithium ions in the electrolyte and the positive and negative electrode active materials form an ion path, an electronic path and an ion path Together form a loop to achieve the purpose of normal work. As the demand for lithium-ion batteries gradually increases, people's performance requirements in all aspects are getting higher and higher, especially for the cycling performance of the battery, and the battery's liquid injection volume is an important parameter to ensure the battery cycle. Too little liquid injection will cause the cycle to decay too fast, causing the battery's service life to decay too quickly. However, too much liquid injection will cause the battery to swell and destroy the overall structure of the battery.
