Abstract

A battery is disclosed, including a battery cell and a protection circuit board. The battery cell includes a cell body; a first tab, and a second tab. The first tab electrically connects the cell body and the protection circuit board. The second tab electrically connects the cell body and the protection circuit board. A polarity of the second tab is opposite to that of the first tab. The third tab electrically connects the cell body and the protection circuit board. A polarity of the third tab is same as that of the first tab, thereby being conducive to reducing temperature rise of the battery cell and the protection circuit board in use. This application further provides an electronic device that uses the battery.
