When the lithium ion battery is operating normally, the negative electrode ends of the negative electrode collector and the positive end of the positive electrode fluid are formed from the outer circuit, the electrolyte and the positive and negative electrode active substances, the ionic passage, electronic pathway and ion passage Cooperate to form a loop to achieve the purpose of normal work. As the demand for lithium-ion batteries is gradually increased, people's performance requirements have become higher and higher, especially regarding the cycle performance of the battery, and the amount of supply of the battery is an important parameter to ensure battery cycle. There will be too little amount of liquid, which causes the cyclic attenuation to be too fast, resulting in a battery life.

But too much amount of liquid can cause battery expansion, destroy the overall structure of the battery. When the traditional lithium-ion battery is supplied, it is generally used for artificial liquid-liquid processing, and the hydrotional precision is low, the liquid is low, the production efficiency is low, and the safety is poor. Although there are also two forms of automatic electrolyte ketvollers in two forms in the prior art in the prior art, the vacuum tether injection molding method is high, the sealing requirements of the equipment pipeline, sealing conditions Strict; while the forward nitting method also has a technical problem with the difficulty of the liquid-liquid precision control.

And the existing tissue machine, which is generally carried out in an atmospheric environment, while if the moisture content in the atmospheric environment is high, the water in the atmosphere and the lithium solute hexafluorophosphate reaction, forming hydrofluoric acid, this to the battery Electrochemical performance and safety performance have a big impact. And the existing tissue machine does not detect the amount of liquid in the liquidation process, and it cannot be discovered instantly discovered the problem of nozzle and equipment problems. And the existing tissue machine, does not have a sealing function, the lithium-ion battery after the liquid, the sealing machine is sealed, the production efficiency is low.

In view of this, Mi Cairo supplies a lithium battery automation production line to solve the low efficiency of the existing lithium ion battery electrolytic solution, poor liquidation accuracy, and no moisture in the atmosphere and electrolyte solute hexafluorophosphate during the atmosphere when nicking. technical problem. Mi Caona lithium battery automation production line can achieve automatic scanning code in the super purification glove box - ketvate - weighing - hydraulic-sealing operation, realizing efficient and complete unmanned automation production, sealing the battery after nipple, battery sealing Automatic completion, high production efficiency.
