Abstract

A cell holder (1) for holding a secondary battery cell (9) including a positive electrode active material, a negative electrode active material, and an electrolyte which is disposed between the positive electrode active material and the negative electrode active material and is in contact with both the positive electrode active material and the negative electrode active material, and for outputting power from the secondary battery cell (9), includes a cell holder body (30), and a pressing portion (10) which is supported by the cell holder body (30) and includes a disc spring (11) being in contact with a first end face of the secondary battery cell (9) in a first direction and pressing the first end face of the secondary battery cell (9) in a second direction opposite to the first direction.

First claim

The invention claimed is:

1. A cell holder for holding a secondary battery cell comprising a positive electrode active material, a negative electrode active material, and an electrolyte which is disposed between the positive electrode active material and the negative electrode active material and is in contact with both the positive electrode active material and the negative electrode active material, and for outputting power from the secondary battery cell, the cell holder comprising:
a cell holder body;
a pressing portion which is supported by the cell holder body and includes a disc spring being in contact with a first end face of the secondary battery cell in a first direction and pressing the first end face of the secondary battery cell in a second direction opposite to the first direction;
a spherical member supported by the cell holder body;
and a plate member which is supported by the spherical member so as to be swingable with respect to the cell holder body and is in contact with a second end face opposite to the first end face of the secondary battery cell.

2. The cell holder according to claim 1 , wherein
a recess is formed in the plate member, and
a part of the spherical member is fitted into the recess, whereby a part of a surface of the spherical member annularly contacts a portion of the plate member forming the recess and the spherical member supports the plate member.

3. The cell holder according to claim 1 , wherein the pressing portion includes a plurality of the disc springs, and the plurality of the disc springs is superposed in a serial combination.
