When the lithium ion battery is operating normally, the negative
electrode ends of the negative electrode fluid and the positive end of the
positive electrode collector form an electronic pathway, an electrolyte and a
positive and negative electrode active material, an electrolyte, and an ion
passage. Together 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 for the cycle performance of the
battery, and the amount of the battery is important parameters to ensure
battery cycle. The amount of liquid can cause the cyclic attenuation to be too
fast, causing the battery life attenuation too fast. However, excessive amount
of liquid can cause a battery expansion, destroy the overall structure of the
In the traditional lithium
battery solution, it is generally used for artificial liquidification, and one-to-one
hydrothermal processing is performed, the liquid-liquid precision is low, low
production efficiency and poor safety.
Although there are also two forms of automatic electrolyte
ketvollers in two forms of forward liquid liquid and vacuum inverted, the
vacuum tether injection molding is high, and the sealing conditions are highly
required. Strict; while the forward nitting method also has a technical problem
that the liquid-liquid precision control is difficult.
And the existing tissue,
which is generally carried out in an atmosphere 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, which is for the battery. Electrochemical performance and
safety performance have a large impact. Moreover, existing tissue can't detect
the amount of liquid in the niche process, which can not be discovered
instantly discovered unqualified problems and equipment problems. As well as
the existing tether, it does not have a sealing function, and the lithium
battery after the nice requires a special sealing machine to be sealed, and the
production efficiency is low.
In view of this, Nichwell
provides a lithium battery automation production line to solve the low
efficiency of existing lithium battery electrolytic solutions, poor liquidation
accuracy, and no moisture and electrolyte solute hexafluorophosphate in the
atmosphere when nicking.
Nichwell lithium battery
automation production line can achieve automatic scanning code in the super
purification glove box - ketvate - weighing - hydraulic-sealing operation,
achieve efficient and complete unmanned automation, sealing the battery after
the stock, battery sealing Automatic completion, high production efficiency.
