Abstract

The invention provides a secondary battery and a battery module. The secondary battery includes: a case having an opening; an electrode assembly accommodated in the case and including a first pole piece; a top cover assembly which comprises a top cover plate and a first electrode terminal, wherein the top cover plate covers the opening and is provided with an electrode lead-out hole, the first electrode terminal comprises a terminal plate, and the terminal plate is located on one side of the top cover plate and covers the electrode lead-out hole; and a wiring board which comprises a main bodypart and an extension part connected with the main body part, wherein the main body part is located on the side, away from the terminal plate, of the top cover plate and connected with the first polepiece, the extension part extends into the electrode lead-out hole to be electrically connected with the terminal plate, the extension part comprises a protrusion arranged on the side, close to the top cover plate, of the main body part, and a concave part is arranged on the one side, away from the terminal plate, of the protrusion.

Description

[0001] This application is a divisional application based on the invention with the application number 201710765949.4, the application date is August 30, 2017, the applicant is Ningde Times New Energy Technology Co., Ltd., and the invention name is "secondary battery and battery module". technical field [0002] The invention relates to the technical field of energy storage devices, in particular to a secondary battery and a battery module. Background technique [0003] New energy vehicles are being widely promoted at home and around the world, but there are still many things to improve in order to completely replace fuel vehicles. For example, the mileage of the car is small, the cost of the battery pack is high, and the reliability of the battery pack needs to be further resolved. Based on the above problems, higher requirements are put forward for the power battery, the core component of electric vehicles, such as higher energy density and lower cost for the power battery...
