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 mater-ial must not leach out contaminating substances into the battery electrolyte as this could have a long-term negative influence on the cells’ electrochemistry.

What are cell sealing components?

The following pages will discuss the main sealing components for cells and the entire battery system. Cell sealing components must electrically isolate the two pole connectors from each other. The sealing components used also have to be chemically stable toward organic electrolytes.

What are plug & seal components?

Plug & Seal components are already being used as standard in vehicle cooling systems and cooling modules of hybrid and electric vehicle batteries. Additional requirements for battery cooling systems can be met with sealed plastic pipe con-nectors and branched, flow-optimized components (Fig. 10.3).

Can a seal design improve battery cooling cycles for electric vehicles?

Kritzer P, Clemens M, Heldmann R (2011) Innovative seals: a robust and reliable seal design can provide eficient battery cooling cycles for electric vehicles and hybrid electric vehicles. Engine Technology International, June 2011, p. 64

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.

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 require-ments need to be met.
