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.
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.

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.
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).
Off-the-shelf usage of lithium-based battery systems in vehicles began in the year 2009 with Daimler AG’s S400 hybrid. In 2011, the first purely electric vehicles with lithium batteries were produced in series. As of today, all battery-driven and plug-in hybrid vehicles contain lithium-based energy storage systems.
