CURRENT COLLECTING POST SEAL FOR HIGH DURABILITY LITHIUM-ION CELLS

摘要

A cover assembly for a Lithium-ionbattery container to improve the durabilityof the battery. A high pressure injectionmolded polymer is combined with flangesdisposed on the current collecting posts of thebattery to provide an improved seal for thebattery cover, especially at the interface of thecover and the current collecting posts. The injectionmolded polymer is fused to theflanges, current collecting posts and containercover to result in a diffusion path of increasedlength for gases and/or liquids which areknown to enter or escape from battery containers.Additional polymer layers can be appliedto the assembly to further improve theseal.
