BATTERY COLOR CHANGE MATERIAL TO VISUALLY INDICATE BATTERY MALFUNCTION
In one aspect, an apparatus includes a battery. The battery includes at least one battery cell, a casing that houses the at least one battery cell, and material coupled to an exterior of the casing. The material is configured to change color based on interaction with matter from the at least one battery cell based on the matter being released from inside the casing.
1 . An apparatus, comprising:
a battery, the battery comprising:
at least one battery cell;
a casing housing the at least one battery cell; and
material coupled to an exterior of the casing, the material configured to change color based on interaction with matter from the at least one battery cell based on the matter leaking from inside the casing.
2 . The apparatus of claim 1 , wherein the material is paper-based.
3 . The apparatus of claim 2 , wherein the material is impregnated with a litmus.
4 . The apparatus of claim 2 , wherein the material is impregnated with delphinidin.
5 . The apparatus of claim 2 , wherein the material is impregnated with a cyanidin.
6 . The apparatus of claim 2 , wherein the material is impregnated with an anthocyanin.
7 . The apparatus of claim 2 , wherein a surface of the material facing away from the casing is laminated with nylon that dissolves based on contact with battery acid or other matter from inside the battery cell.
8 . The apparatus of claim 2 , wherein a surface of the material facing away from the casing is laminated with nitrile that dissolves based on contact with battery acid or other matter from inside the battery cell.
9 . The apparatus of claim 1 , wherein based on interaction with matter from the at least one battery cell, the material changes to a red color from a non-red color.
10 . The apparatus of claim 6 , wherein the non-red color is a blue color.
11 . The apparatus of claim 1 , wherein the material is non-toxic.
12 . An apparatus, comprising:
a casing for at least one battery cell; and
material coupled to the casing, the material configured to change color based on contact with matter from the at least one battery cell based on the matter being released external to the casing from inside the casing.
13 . The apparatus of claim 12 , wherein the material is paper-based.
14 . The apparatus of claim 12 , wherein the material comprises a litmus.
15 . The apparatus of claim 12 , wherein the material comprises delphinidin.
16 . The apparatus of claim 12 , wherein the material comprises a cyanidin.
17 . The apparatus of claim 12 , wherein the material comprises an anthocyanin.
18 . The apparatus of claim 12 , wherein a surface of the material facing away from the casing is laminated with nylon and/or nitrile.
19 . The apparatus of claim 12 , wherein based on interaction with matter from the at least one battery cell the material changes to a color from the red analogous color group.
20 . A method, comprising:
providing at least one battery cell;
providing a casing housing the at least one battery cell; and
providing material coupled to an exterior of the casing, the material configured to change color based on interaction with matter from the at least one battery cell based on the matter being released from inside the casing.
