Abstract
A multicell sealed rechargeable battery is disclosed including an open mouth monobloc container formed of a plurality of cup-shaped cell holders interconnected at mutual tangent zones, electrochemical cells of the rechargeable type fitting into the cell holders and interconnected to form the battery, and a closure member attached to the mouth of the monobloc container.
Claims12
A multicell sealed rechargeable battery and housing therefor capable of withstanding variable internal pressures, comprising:
- an open mouth substantially rigid monobloc container including a plurality of cup-shaped cell holders of internal substantially cylindrical shape each interconnected to at least one adjacent cell holder at mutual circumferential tangent zone(s), to define common substantially non-deformable intercell partitions at such zones;
- non-self-contained electrochemical cells having plates and separator spirally wound together in substantially cylindrical shape closely fitting in said cell holders and electrically interconnected to form a battery;
- and
- a closure member attached to the monobloc container at its mouth.
A multicell sealed rechargeable battery and housing therefore capable of withstanding variable internal pressures, comprising:
- a substantially open mouth rigid monobloc container comprised of a plurality of cylindrical cup-shaped cell holders each interconnected to at least one other cell holder at mutual circumferential tangent zone(s), to define common substantially nondeformable intercell partitions at such zones;
- individually sealed electrochemical spirally wound cell pack elements contained within sealed plastic liners of substantially cylindrical shape closely fitting in said cell holders and electrically interconnected at the mouth opening of the monobloc with intercell connectors bridging over said intercell partitions;
- and each of said cell packs being sealed in gas and liquid tight manner within its own plastic liner and top, fitting snugly within the cell holders and opposite polarity terminals protruding out through said top, a portion of which terminals are bent over and interconnected directly with terminals of an adjacent cell;
- a closure member attached to the monobloc container at its mouth.
