Why do batteries need to be sealed?
The sealing components used also have to be chemically stable toward organic electrolytes. In addition, during the battery’s entire service life, the sealing material must not leach out contaminating substances into the battery electrolyte as this could have a long-term negative influence on the cells’ electrochemistry.
What type of sealing is used for power electronics?
The sealings to connect power electronics are usually integrated directly into the plug. Silicon rubber-based components are used for this application in most cases. They have increased resistance toward high electrical voltages, and their surface does not carbonize, as opposed to carbon-based polymers.
Why do batteries need gaskets?
Opening the housing usually destroys the gasket because it sticks to the lid or the housing. This causes battery maintenance problems because in order to seal the housing again, a new lid with sprayed-on gasket is required. This is the reason why large-scale gaskets are used when tough technical requirements need to be met.
What is the minimum protection rating for battery housing gaskets?
In general, automotive applications require at least protection rating IP67 (ISO 20653:2006 – 08) for battery housing gaskets. Thus, the battery housing must be dust-proof and also resistant to outside water pressure of 0.1 bar for at least 30 minutes.
What materials are used to seal solid housing cells?
Currently, thermoplastic materials such as polypropylene, polyamide (PA 12), or perfluoroalkoxy (PFA) polymers are generally used to seal solid housing cells.
