摘要： The present disclosure relates to an insulation plate for a secondary battery and a secondary battery. The insulation plate includes two side portions and a top portion between the two side portions. Each of the two side portion includes a transverse covering portion and a longitudinal covering portion that are used to cover a transverse transition part and a longitudinal transition part of an electrode assembly of the secondary battery, respectively. During placing the electrode assembly into a case of the secondary battery, since transition parts of the electrode assembly are covered by the insulation plate, the transition parts of the electrode assembly are prevented from directly contacting the case, thereby reducing the possibility of being scratched and rubbed by the opening of the case. Therefore, electrical connection between negative and positive electrode plates of the electrode assembly is avoided and thus the reliability of the secondary battery is improved.

摘要： The present disclosure relates to a vent for a secondary battery top cover, a top cover assembly, a secondary battery and a vehicle. The vent includes a flat base and a protrusion protruding outward with respect to flat base. The protrusion has a main nick and at least one branch nick connected to at least one end of the main nick. An angle formed between the main nick and the branch nick is more than zero. When the pressure inside the case increases excessively, gas causes stress concentration at the protrusion such that the vent is torn along the main nick and the at least one branch nick, thereby releasing the gas in the case, reducing explosion risk of the secondary battery, and improving safety of the secondary battery.
