Abstract
A Lithium-Ion monoblock battery assembly including a housing having a cavity for receiving an electrode assembly. Also including a cover sealingly attached to the housing, and a bussing integrally molded with at least one of the housing and the cover.
Claims14
A monoblock lithium-ion battery assembly comprising:
- a housing made from a polymer material and having multiple, separately individually hermetically sealed, but electrically connected cavities, each cavity receiving an electrode assembly, electrolyte, the electrode assembly being in direct contact with the housing,
- a cover distinct from the housing and sealingly attached to the housing, and being over-molded around a bussing,
- the electrode assembly having a terminal extending out of an opening of the cavity, the bussing being connected to the terminal via laser welding.
A lithium-ion monoblock battery assembly comprising:
- a housing made from a material and having multiple, separately individually hermetically sealed, but electrically connected cavities, each cavity receiving an electrode assembly, electrolyte, the electrode assembly being in direct contact with the housing, the plurality of cavities being divided by divider walls,
- an electrode assembly received in each cavity,
- a cover sealingly attached to the housing, and,
- a bussing being over-molded into the divider walls,
- the electrode assembly being blind laser welded from an outside of the monoblock battery assembly to the bussing.
