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.
