## Abstract

There is disclosed an electric battery assembly comprising: a plurality of electric batteries arranged in an array, an interconnection for connecting batteries in the array to provide a common power output; a plurality of shock absorbent housings, wherein each electric battery is provided within a shock-absorbent housing. The shock absorbent housing may have the form of a blister, which may be flexible and which may be filled with a shock-mitigating material.

## Claims

### Claim 1

An electric battery assembly comprising:
a plurality of electric batteries arranged in an array;
an interconnection for connecting batteries in the array to provide a common power output; and
a plurality of shock absorbent housings,
wherein each electric battery is provided within a shock-absorbent housing.

### Claim 2 (depends on 1)

The electric battery assembly according to claim 1 wherein the shock absorbent housing has the form of a flexible blister.

### Claim 3 (depends on 2)

The electric battery assembly according to claim 2 wherein the flexible blister is filled with a shock-mitigating material.

### Claim 4 (depends on 3)

The electric battery assembly according to claim 3 wherein the shock-mitigating material comprises air.

### Claim 5 (depends on 1)

The electric battery assembly according to claim 1 wherein the shock absorbent housings are affixed to a flexible substrate.

### Claim 6 (depends on 5)

The electric battery assembly according to claim 5 wherein the flexible substrate is formed from reinforced composite.

### Claim 7 (depends on 1)

The electric battery assembly according to claim 1 wherein the array of batteries is arranged in a substantially planar form and the interconnection comprises:
a. a first conductive member suspended over the array of batteries; and
b. a second conductive member suspended under the array of batteries;
wherein for each battery there is provided a first connection extending between a positive electrode of the battery and the first conductive member, and
for each battery there is provided a second connection extending between a negative electrode of the battery and the second conductive member.

### Claim 8 (depends on 7)

The electric battery assembly according to claim 7 wherein the first conductive member is in the form of a sheet and wherein the second conductive member is in the form of a sheet.

### Claim 9 (depends on 1)

The electric battery assembly according to claim 1 wherein there is a single battery provided in each shock-absorbent housing.

### Claim 10 (depends on 5)

The electric battery assembly according to claim 5 wherein the shock absorbent housings taper as they extend from the flexible substrate and are separated to permit flexion.

### Claim 11 (depends on 1)

The electric battery assembly according to claim 1 wherein the shock absorbent housings have a substantially hemi-spherical form.

### Claim 12 (depends on 1)

The electric battery assembly according to claim 1 wherein each of the plurality of batteries has a substantially planar form.

### Claim 13 (depends on 8)

The electric battery assembly according to claim 8 wherein at least one of the first or second conductive members is a mesh.

### Claim 14 (depends on 13)

The electric battery assembly according to claim 13 wherein the mesh comprises fuse wire.

### Claim 15 (depends on 1)

The electric battery assembly according to claim 1 wherein the shock absorbent housing has the form of a blister filled with shock-mitigating material, and wherein at the blister, the volume ratio of the battery to the shock-mitigating material is in the range of 1:1 to 1:10.
