Title: ELECTRODE LEAD-OUT SHEET AND BATTERY
Abstract:
Provided is an electrode lead-out sheet, comprising a body portion and a fuse portion located on the body portion. A cross-sectional area of the fuse portion in a width direction of the electrode lead-out sheet is smaller than a cross-sectional area of the body portion in the width direction of the electrode lead-out sheet, wherein the electrode lead-out sheet is provided with a heat pipe disposed adjacent to the fuse portion. Meanwhile, the present invention also provides a battery comprising the electrode lead-out sheet provided by the present invention. According to the electrode lead-out sheet provided in present invention, a heat pipe is disposed on a portion of the body portion adjacent to the fuse portion. When the battery is working normally, in the process of normal overcurrent, although there will be a certain temperature rise due to small overcurrent area and a large resistance value in the fuse portion, with the help of the heat pipe, this part of heat can be timely and quickly emitted, so as to timely dissipate heat, reduce the temperature, and eliminate the influence on the normal use of the battery caused by the temperature rise, and to avoid the abnormal fusing of the fuse portion in normal work.
