The fully-sealed cylindrical ternary power lithium battery glass packaging cover group is one of KWT's new product series, which is mainly designed to cooperate with new energy vehicle power lithium batteries and communications, instrumentation, and military lithium batteries. Due to the unstable high-temperature structure of the ternary lithium battery nickel-cobalt-aluminum, the high-temperature safety is poor, and the high pH value will easily cause the monomer to swell and cause danger. The traditional ternary lithium battery is sealed with fluorine plastic and O-type fluorine plastic ring. In the process of long-term use of the battery, the fluorine plastic and O-type fluorine plastic ring are affected by factors such as environment, temperature, time, etc., which are prone to aging and damage, leading to the battery Undesirable conditions such as liquid leakage and air leakage have seriously affected the service life of the battery. KWT has developed a fully sealed cylindrical ternary power lithium battery glass package cover group. The cover group core column and cover plate are insulated by glass. , The cover assembly and the steel shell are sealed by laser welding/argon arc welding, which completely avoids the material aging problem caused by the use of fluoroplastics and O-shaped fluoroplastics for sealing, and improves the safety performance and service life of the battery....
