Lithium Battery Electrolytic Solution for Vacuum Function

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 battery.

  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.

How to Solve the Glove Box?

The hydrogen content of the glove box is greater than 200ppm. Cause: New box debugging or false operation. Method: Stop loop, turn it on, clean it to 100 ppm, turn on the loop. ;

     Glove box screen shows that the main valve pressure is less than 0.4 MPa or the main valve signal failure Cause: The gas source pressure is insufficient. Measures: ventilation bottle, increase the pressure to 0.4-0.5 mPar;

     The glove box screen reveals the reason for "pump switch off": the vacuum pump resistance is too large, causing trip. Method: After repairing the vacuum pump, turn on the electric cabinet and close the trip switch;

     Causes of glove boxes cannot be opened: the voltage does not stabilize the inverter protection, resulting in a loop that cannot be turned on. METHODS: After the et al., Restart the glovebox to resolve the glove box.

     When the glove box is regenerated, the amount of gas is much smaller than the former reasons: this is mostly too high in the box, and the organic solvent enters the circulatory system during the cycle, and the organic solvent blocks the unidirectional valve on the regenerated air pipeline when regenerated. Measures: 1 Change the one-way valve as a straight valve, which is set to 0.03 ~ 0.04 MPa; 2 Observe whether the regenerative gas flow meter is displayed in 20 ml / min, otherwise adjust the pressure reduction valve pressure;

     Glove box cycle and analyzer simultaneously turn off the reason: 1 pressure in the box is too high, exceeding + 12MBAR, system automatic protection; 2 voltage is unstable, causing system protection. Measures: Check that the pressure setting is correct, whether the pressure sensor is abnormal, whether the box vacuum valve or the pneumatic valve is damaged, and the pressure is returned to normal, and then the analyzer and cycle are turned on.

     The glove box is large, the small warehouse does not allow for the reason: 1 The air hole to the large and small bin in the glove box may be blocked by a plastic film; 2 whether the solenoid valve is not opened. Measures: Determine the pore position, dredge the line according to the pipeline direction, and the line and solenoid valve;

     The glove box is unable to absorb the reason: 1 The pumping hole in the large and small warehouse is blocked or the door is blocked or the cabin is leaking; 2 may be the warehouse door is not tight, 3 is the size of the small bullion seal. Measures: 1 According to the pipeline, determine the position, dredging the line; 2 Tight the warehouse, check the size seal; 3 Check if the working air pressure is too low (because the big warehouse pumping valve is a pneumatic valve);

     The box is cleaned when the box is complicated: the cleaning valve is not open, the intake pressure is too large, the pipeline is not smooth. Method: 1 guarantee that the pipeline is smooth, it is best not to be bent; 2 When cleaning, the relative pressure in the box continues below 0.5 mbar.

     Causes of the main valve failure: 1 Work air pressure is less than 0.5MPa; 2 Main valve signal feedback fault solution: 1 Replace the working cylinder, or check the pressure relief valve side pressure at 0.5 MPa; 2 Check the main valve signal switch;

     Glove box loop cannot be opened: the fan inverter low pressure or high pressure protection. Solution: After the voltage is stable, turn it off after 1 minute.

How to Distinguish Your Glove Box?

The concept and equipment of the glove box equipment has been introduced to our country. The principles and manufacturing processes have been digested by domestic gloves manufacturers. The products of domestic glove box manufacturers are gradually mature, but domestic large and small gloves boxes. Manufacturers produce the level of technologies, uniform, air tightness, durability, and oxygen-proof penetration resistance.

    The quality of the glovebox is specifically in:

1, the glove box box is compressed, but it may consume 1 bottle of inert gas for 2 days;

2, the glove box gas leaks are unhappy, reaches the compressive standard, but the oxygen indicator does not meet the standard, it is not possible to stably control the standards less than 1 ppm, which is the difference between the sealing material and the seal, the water oxygen is more, and the oxygen enters the glove box body Inert atmosphere, reduce the purity of an inert atmosphere;

3, the accuracy and durability of the oxygen probe of the glove box are uneven. Different probes used in domestic different gloves, the material is different, the probe service life and test accuracy are different, and the detection data of the atmosphere in the glove box may not Real oxygen content of the reaction glove box atmosphere;

4, the technical source of the glove box products of different domestic manufacturers is different or the principle of the company's products, the production process, industry experience will also affect the stability, durability and data accuracy of the factory glove box product.

5. Some companies that are purely simply equit, there is a phenomenon of crude, there is no technical reserve, which will be very bitter after purchase.

Glove Box

The glove box is a laboratory apparatus that charges the high purity inert gas into the box and circulates the laboratory equipment of the active substance in which it is filtered out. Also known as a vacuum glove box, an inert gas protection box, etc.

The main function of the glove box is to remove O2, H2O, and organic gases. Glove box is widely used in anhydrous, aerobic, dust-free ultrapure environment, such as lithium ion batteries, semiconductors, supercapacitors, special lamps, laser welding, brazing, material synthesis, OLED, MOCVD, and the like. It also includes biological applications such as anaerobic culture, cell hypoxic culture, etc..

Use of glove box

The glove box operates to isolate air to experiment, such as metal lithium, in case of oxygen, and some reactions need to be carried out in an inert gas such as an argon environment. Use lead and lead glass to protect with lead and lead glass using open (no shield). Protect the experimenter from harm to toxic chemicals. It is thorough than the ventilator, but it is more inconvenient to operate. Mainly used in a particular toxicity. Performing experiments that may cause serious biometric hazards, such as strong bacteria.

Glove box structure principle editing

The glove box is mainly composed of two parts of the main box, the transition chamber. If the user has other special requirements, it can also be designed and manufactured as needed.

There are two (or more than two) gloves on the bodies of the glove box, which is distributed in front of the box (or both sides of the front and rear), which allows the operating case to operate at the same time, improved The use efficiency of the box. In addition, there is a viewing window in front of the glove box case, and the operator can clearly observe the operation of the box, so that the operation process is intuitively present in front of the operator. There is a pumping and inflatable nozzle on the valve of the glove box transition chamber, which can be accessed when you need to pick up or inflate. The glove box is also installed on the main box. There is a valve and nozzle, and the user can use when it is necessary to maintain the air pressure balance, can be used (the three-way valve between the glitter port can be used when necessary) . The sunlight is installed on the front viewing window of the main box.

The glove box transition chamber is a transition space as the main box and the box, which is composed of two sealing doors and two valves and a chamber body. The inside and outside the door can effectively accept the contact of the main box and the outside, so that things inside and outside the cabinet can enter and exit in the case of the main box and atmosphere, thereby avoiding repetitive vacuum and inflation.

Glove boxes also have industrial gloves and bio-gloves.

Industrial glove box

What do You Need to Prepare Before Your Glove Box?

The glove boxes commonly used in the laboratory are mainly composed of a chamber, a gas purification system, two antechambers, a vacuum pump, a control system, and an additional function. Glove box equipment is a test instrument that thoroughly seals vacuum.

     When we use the vacuum glove box, gas is purified from the fuel tank filter and purify the system, and returned to the fuel tank equipment repeated circulation. The main diluent is separated from radioactive substances or other toxic substances, and the glove box is equipped with a peep window, which is easy to test operation .

     Thus, we also have some general precautions when operating the glove box. If you should consult a special drug or unconventional item before the operation, users cannot leave a nail, or they cannot carry or damage the jewelry, rings or other of the gloves. The operator must wear gloves in the glove of the glove box. Before using it, check the working pressure on the glove box panel, adjust the adjustment between ± 4 MBar. The moisture and oxygen content should be insisted on <0.1 ppm; the cylinder must have sufficient gas supply to complete the operation (ie, the pressure gauge must ensure that there is a number of draws).
