Abstract

A battery pack and a battery proofed against counterfeiting is provided. The outer surface of the exterior material of the battery and the outer surface of the battery pack are each provided with a light emitting material which, when irradiated with invisible light, emits visible light.

Claims

1. A battery identifier provided on a battery or a battery pack thereof, the battery identifier comprising a light emitting material that is colorless against a visible light wherein the light emitting material is capable of emitting the visible light when illuminated by an invisible light.

2. The battery identifier according to claim 1, wherein the invisible light includes an ultraviolet light.

3. The battery identifier according to claim 1, wherein the light emitting material includes an inorganic phosphor material.

4. A battery comprising:

a battery element having a cathode and an anode;

an exterior material for accommodating the battery element therein; and

a battery identifier provided on an outer surface of the exterior material,

the battery identifier including a light emitting material that is colorless against a visible light wherein the light emitting material is capable of emitting the visible light when illuminated by an invisible light.

5. The battery according to claim 4, wherein the invisible light illuminated on the battery identifier includes an ultraviolet light.

6. The battery according to claim 4, wherein the light emitting material includes an inorganic phosphor material.

7. A battery pack comprising:

a battery provided with a cathode and an anode, wherein the battery operates as a power generating element;

a battery case for accommodating the battery therein; and

a battery identifier provided on an outer surface of the battery case,

the battery identifier containing a light emitting material that is colorless against a visible light wherein the light emitting material is capable of emitting the visible light when illuminated by an invisible light.

8. The battery pack according to claim 7, wherein the invisible light includes an ultraviolet light.

9. The battery pack according to claim 7, wherein the light emitting material includes an inorganic phosphor material.
