Shroud for electrical cell connection of stacked accumulator modules and lithium ion accumulators used for motor car, has receiving chamber totally or partly filled with encapsulation material and enclosing connection in airtight manner

摘要

The shroud has a receiving chamber (1) totally or partly filled with an encapsulation material (26). The receiving chamber encloses an electrical cell connection (2), which includes a copper electrode (3), an aluminum electrode (4) and a cell connector (5), in an airtight manner. The encapsulation material comprises a mixture of calcium lithium soap grease and non-metallic powder such as silicon dioxide. An aperture (9) is formed corresponding to the copper electrode in a ceiling (8) of the receiving chamber. Independent claims are also included for the following: (1) a stacked accumulator module using a shroud (2) a method for stacking lithium ion accumulator modules including multiple accumulator cells.
