Abstract

A battery cell assembly and a method for assembling the battery cell assembly are provided. The battery cell assembly includes first and second rectangular ring-shaped panel members and at least one battery cell. The first and second rectangular ring-shaped panel members are configured to easily couple together to hold the battery cell therebetween.

Claims

1. A battery cell assembly, comprising:

a first rectangular ring-shaped panel member having first and second side walls, a first top wall, and a first bottom wall, the first and second side walls being substantially parallel to one another and being disposed between the first top wall and the first bottom wall, the first side wall having a first coupling member, the second side wall having a first ledge portion;

a second rectangular ring-shaped panel member having third and fourth side walls, a second top wall, and a second bottom wall, the third and fourth side walls being substantially parallel to one another and being disposed between the second top wall and the second bottom wall, the third side wall having a second coupling member, the fourth side wall having a second ledge portion, such that the first coupling member of the first side wall of the first rectangular ring-shaped panel member engages the second ledge portion of the fourth side wall of the second rectangular ring-shaped panel member and the second coupling member of the third side wall of the second rectangular ring-shaped panel member engages the first ledge portion of the second side wall of the first rectangular ring-shaped panel member;

a first battery cell having a first peripheral lip portion;

a second battery cell having a second peripheral lip portion; and

a gasket disposed between the first and second peripheral lips portions of the first and second battery cells, respectively, and contacting the first and second peripheral lip portions, the first and second battery cells and the gasket being

fixedly held between the first and second rectangular ring-shaped panels.

2. The battery cell assembly of claim 1, wherein the first battery cell further includes a first body portion, and the first peripheral lip portion extending around a periphery of the first body portion, the first peripheral lip portion being disposed between the first and second rectangular ring-shaped panel members.

3. The battery cell assembly of claim 1, wherein the first rectangular ring-shaped panel member and the second rectangular ring-shaped panel member are constructed from plastic.

4. The battery cell assembly of claim 1, wherein the second side wall further has a third coupling member, the first side wall further having a third ledge portion, the fourth side wall further having a fourth coupling member, the third side wall further having a fourth ledge portion, such that the third coupling member of the second side wall of the first rectangular ring-shaped panel member engages the fourth ledge portion of the third side wall of the second rectangular ring-shaped panel member and the fourth coupling member of the fourth side wall of the second rectangular ring-shaped panel member engages the third ledge portion of the first side wall of the first rectangular ring-shaped panel member.

5. A method for assembling a battery cell assembly, the battery cell assembly having a first rectangular ring-shaped panel member with first and second side walls, a first top wall, and a first bottom wall, the first and second side walls being substantially parallel to one another and being disposed between the first top wall and the first bottom wall, the first side wall having a first coupling member, the second side wall having a first ledge portion, the battery cell assembly further having a second rectangular ring-shaped panel member with third and fourth side walls, a second top wall, and a second bottom wall, the third and fourth side walls being substantially parallel to one another and being disposed between the second top wall and the second bottom wall, the third side wall having a second coupling member, the fourth side wall having a second ledge portion, the method comprising:

disposing a gasket member between first and second peripheral lip portions of first and second battery cells, respectively;

disposing the first and second battery cells and the gasket between the first and second rectangular ring-shaped panel members;

engaging the first coupling member of the first side wall of the first rectangular ring-shaped panel member to the second ledge portion of the fourth side wall of the second rectangular ring-shaped panel member; and

engaging the second coupling member of the third side wall of the second rectangular ring-shaped panel member to the first ledge portion of the second side wall of the first rectangular ring-shaped panel member, such that the first and second battery cells and the gasket are fixedly held between the first and second rectangular ring-shaped panel members.
