## Abstract

A battery retainment block includes a plurality of block pieces each having a battery storage unit for retaining a battery. The plurality of block pieces are aligned and, among the plurality of block pieces, two block pieces that are adjacent to each other are coupled together. A gap is provided between the two block pieces that are adjacent to each other to serve as a circulation space for circulating a medium.

## Claims

### Claim 1

A battery retainment block, comprising:
a plurality of block pieces formed in a shape for retaining a battery, wherein
the plurality of block pieces are arranged, and at least one of the two block pieces that are adjacent to each other, among the plurality of block pieces, includes a convex part, and a concave part having an outer peripheral face which is more recessed than an outer peripheral part of the convex part, wherein the convex part is coupled to the other one of the two block pieces that are adjacent to each other, and
a circulation space for circulating a medium is provided between the concave part and the other one of the two block pieces.

### Claim 2

(canceled)

### Claim 3 (depends on 1)

The battery retainment block according to claim 1, wherein
at least one of the two block pieces that are adjacent to each other is formed in a cylindrical shape, and has a large diameter part, and a small diameter part having a diameter that is smaller than the large diameter part,
the large diameter part is coupled to the other one of the two block pieces that are adjacent to each other, and
a gap is formed as the circulation space between the small diameter part and the other one of the block pieces.

### Claim 4 (depends on 1)

The battery retainment block according to claim 1, wherein the circulation space is disposed at a center part of the block piece in an axial direction.

### Claim 5 (depends on 4)

The battery retainment block according to claim 4, p1 wherein a length of the block piece in the axial direction in the circulation space is 30 to 80% of a length of the battery.

### Claim 6 (depends on 1)

The battery retainment block according to claim 1, wherein
at least three first direction rows each having a plurality of block pieces arranged in a row along a first direction are formed,
the at least three first direction rows are arranged in a second direction that intersects with the first direction, and
a block piece of one of the adjacent two first direction rows and a block piece of the other one of the adjacent two first direction rows are disposed alternately.

### Claim 7 (depends on 1)

A battery module, comprising:
the battery retainment block according to claim 1; and
a battery retained in the battery retainment block.
