BATTERY WITH POP-UP MECHANISM TO VISUALLY INDICATE BATTERY MALFUNCTION AND/OR TO ELECTRICALLY DISENGAGE BATTERY FROM DEVICE
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 a mechanism inside the casing. The mechanism includes a shaft that moves within the casing based on leakage of matter from the battery cell to outside 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
a mechanism inside the casing, the mechanism comprising a shaft that moves within the casing based on leakage of matter from the battery cell to outside the casing.
2 . The apparatus of claim 1 , wherein the shaft is configured to electrically disengage the battery from a device based on movement of the shaft based on the leakage.
3 . The apparatus of claim 1 , wherein the shaft is configured to extend a component of the battery away from the casing based on movement of the shaft based on the leakage.
4 . The apparatus of claim 3 , wherein the component comprises at least part of the shaft.
5 . The apparatus of claim 3 , wherein the component as extended away from the casing establishes a visual indicator appreciable from outside the casing without deconstructing the battery.
6 . The apparatus of claim 5 , wherein the visual indicator indicates a battery malfunction.
7 . The apparatus of claim 6 , wherein the component as extended away from the casing bears red coloring to indicate the battery malfunction.
8 . The apparatus of claim 1 , wherein the mechanism comprises an element with an opening through which the shaft extends, the element configured to expand the opening based on the leakage to permit the shaft to move within the casing based on the leakage.
9 . The apparatus of claim 8 , wherein the shaft has a first width along a first portion of the shaft and has a second width along a second portion of the shaft, the second width being larger than the first width, the element configured to expand the opening based on the leakage to permit the second portion to move within the casing to extend a component of the battery away from the casing.
10 . The apparatus of claim 9 , wherein the second portion cannot pass through the opening prior to the opening's expansion based on the leakage.
11 . The apparatus of claim 10 , wherein the second portion abuts the element around at least a portion of the opening prior to the opening's expansion based on the leakage.
12 . The apparatus of claim 8 , wherein prior to the opening's expansion based on the leakage the opening establishes an interference fit with the shaft, the interference fit preventing movement of the shaft within the casing, and wherein based on the opening's expansion based on the leakage the shaft moves within the casing.
13 . The apparatus of claim 8 , wherein the element is ring-shaped.
14 . The apparatus of claim 8 , wherein the element is established at least in part by a polymer.
15 . The apparatus of claim 1 , wherein the matter comprises electrolyte.
16 . The apparatus of claim 1 , comprising a device that houses the battery.
17 . An apparatus, comprising:
a mechanism configured for disposition within a battery, the mechanism comprising a shaft configured to move within a casing of the battery based on leakage of matter from the battery cell to outside the casing.
18 . The apparatus of claim 17 , wherein the mechanism comprises an element with an opening configured for receiving the shaft, the element configured to expand the opening based on leakage of electrolyte out of a battery cell of the battery to permit the shaft to move within the opening based on the leakage.
19 . The apparatus of claim 18 , wherein an end portion of the shaft is configured with an indicator of electrolyte leakage.
20 . A method, comprising:
providing a battery comprising at least one battery cell and a casing housing the at least one battery cell; and
providing a pop-up mechanism inside the casing, the pop-up mechanism comprising a shaft that moves within the casing based on leakage of matter from the battery cell to outside the casing.
