BATTERY AND ELECTRONIC DEVICE

A battery and an electronic device are provided. The battery includes an electrochemical cell and an FPC. No protection circuit is disposed on the electrochemical cell and the FPC. A first part of the FPC is stacked on a top seal in a width direction of the electrochemical cell, two second parts are formed by respectively extending from two ends of the first part, and second connection parts are respectively disposed at extension ends of the two second parts. One of the second connection parts is connected to a positive trace in the FPC, and the positive trace extends from the corresponding second connection part, through a corresponding second part, to a position opposite to a positive electrode tab. The other second connection part is connected to a negative trace in the FPC, and the negative trace extends from the corresponding second connection part, through a corresponding second part, to a position opposite to a negative electrode tab. At least two positive electrode tabs or at least two negative electrode tabs are disposed. In this way, both the positive trace and the negative trace in the FPC are arranged in a unipolar manner, so that a safety risk like fire caused by a sustained short circuit can be avoided, and link impedance of the FPC can be reduced.
