Newknow-how appeared in the 2016 Assembly Engineering lithium tour

March 25, 2016 by the senior engineers to join the Air lithium-lithium, "2016 Supply Chain Engineering lithium good product tour Conference" Changzhou Jintan People's Government jointly organized was held in Changzhou, Jintan Run Australian Garden Hotel. Outstanding enterprises from the new energy vehicles, batteries, equipment and materials of the whole industry chain of super 300 leaders attended the meeting were then new demands and new trends of new energy vehicles Times.

As the world's most professional helium leak detection system integrators - Guangzhou New Dragon-ho Industrial Equipment Co. unveiled at the summit, Mr. New Dragon-ho, general manager Lin Qiwu issued a "helium leak detection technology in the manufacture of lithium application" theme speech, contribute to the cause for the full swing of lithium.

Lin Qiwu said that in the lithium-ion battery industry, the product will result in poor battery performance sealed a serious decline, electrolyte penetration, battery explosion bulge or even serious consequences, therefore, crucial to the merits of the lithium-ion battery tightness.
 
Lithium-ion batteries on the market depending on the housing, the plastic housing is divided into a lithium ion battery, lithium ion battery and the metal shell plastic film flexible packaging lithium-ion batteries are three pre lithium-ion battery industry to use more positive bubble detection drain method, this type of detection method is easy to cause the battery casing deformation occurs is difficult to recover, especially for the metal housing and plastic film flexible packaging lithium-ion does not apply, coupled with lower detection efficiency and accuracy rate, as soon as possible so the search for a suitable leak detection method is imminent.
 
 "He seized power battery manufacturers of the degree of attention and understanding are not enough, but there is no uniform industry standard Helium industry, so there is a certain distance from large-scale application of technology in Helium battery manufacturing process." Lin Qiwu representation , helium in improving battery safety and consistency will play a huge role, but the technology has not been sufficient attention to the battery business, the key lies in battery manufacturing helium urgent need to establish industry standards.
  
During the meeting also introduced special battery leak detection program:

  1, the front intermediate housing leak liquid injection, can effectively prevent the electrolyte sealing small leaks are pouring back, resulting in a short time could not be determined but the leak will affect the adverse affect battery performance and life. For the hard shell of the battery power can be detected by increasing the pressure to quantify the level of battery drain test conditions at different pressures and better long-term analysis of cell sealing and strength.
 
  2, cell preconditioning helium, can effectively guarantee the level of leakage of battery products, while the injection port is also the final seal leak detection, make sure the battery finished product consistency and safety.
 
  3, using Helium can significantly reduce the time a conventional immersion test can be done to achieve accurate results within one minute leaks conclusions and avoid the subsequent step of drying the next step, while a more quantitative analysis whether the protection indicators. Suction gun helium leak configuration, the tester can also help pinpoint the leak, so do the processing step after step.
