摘要: A battery includes a shell having an inner cavity; a wound core assembled in the inner cavity of the shell; a column supported in the wound core, wherein the column includes a first cavity for storing a lithium-replenishing medium and a second cavity for storing a fire-fighting medium, a cavity wall of the first cavity having a first hole, and a cavity wall of the second cavity having a second hole; a first membrane configured to block the first hole, and configured to break when subjected to a first pressure, allowing the lithium-replenishing medium in the first cavity to flow into the inner cavity; and a second membrane configured to block the second hole, and configured to break when subjected to a second pressure, allowing the fire-fighting medium in the second cavity to flow into the inner cavity, the second pressure being greater than the first pressure.
