A vent assembly for a battery or a electrochemical cell may include a vent body configured to connect to a battery casing or a electrochemical cell body, a flame arrester and/or a pressure valve disposed in the vent body, a membrane disposed in the vent body between a vent opening of the battery or the electrochemical cell and the flame arrester and/or the pressure valve, and that is configured to shield the flame arrester and/or the pressure valve from electrolyte solution of the battery or the electrochemical cell, and a seal disposed between the vent body and the membrane. Also, a battery including a vent assembly.

Vent assembly with membrane

Provided is a battery that may include a first terminal or cable, a second terminal or a cable, a thermal fuse configured to connect to the first terminal or cable and the second terminal or cable, a first sleeving layer that is disposed on the thermal fuse, and that is configured to muffle an arc explosion of the thermal fuse and encapsulate molten material generated by the arc explosion of the thermal fuse, and a second sleeving layer that is disposed on the first sleeving layer, and that is configured to encapsulate the molten material generated by the arc explosion of the thermal fuse that penetrates the first sleeving layer. An overcurrent protection system and a sleeving are also provided.
