Abstract
Devices for insulating the electrical terminals of cylindrical batteries, such as lithium-ion cells, to prevent the occurrence of shorting. One configuration is a device or apparatus which covers one or more terminals of the cell, thereby providing an insulative barrier, while still allowing the cell to be used. Another configuration is a cell covering partially covering the topmost portions of the negatively charged exterior cell case, closest to the positive terminal of the cell, and attaching the covering via a circumferential appendage which locks onto the cell. In another configuration the cell covering extends axially down the side of the cell case to cover part of, or the entirety of, the side of the negatively charged case.
