Abstract

The invention provides a battery which comprises a battery cell and a shell, the shell is located on the periphery of the battery cell, and a top sealing edge and a side sealing edge are formed on the edge of the battery cell of the shell; wherein the side sealing edge comprises a first main body part and a first extension part, the first main body part is positioned on the side end surface of the battery, the side end surface is the end surface of the battery along the width direction, and the first main body part is bent towards the side end surface; the first extension part extends out of the top end surface of the battery along the height direction of the battery, the top end surface is the end surface of the battery along the height direction, and at least partial area of the first extension part is bent towards the first main body part and is positioned on one side, facing the side end surface, of the side sealing edge. According to the battery provided by the invention, the electric capacity of the battery cell can be improved, the endurance time of the electronic equipment can be prolonged, and in addition, the end part of the side sealing edge can be prevented from being corroded, so that the use safety of the battery can be improved.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a battery. Background technique [0002] A battery is a device that can store electrical energy inside to power external devices (such as mobile phones, tablets, laptops, personal digital assistants, and other portable or mobile electronic devices) when needed. At present, with the increasing size of mobile phone screens and the development of the fifth generation mobile communication technology (5th Generation Mobile Communication Technology, referred to as 5G), the power consumption of mobile phones is getting higher and higher. [0003] Generally, a battery includes a battery cell and a casing located on the periphery of the battery cell. The battery cell is packaged through the casing, and the casing is made of aluminum-plastic film material to protect the battery. [0004] However, in the related art, the casing of the battery, for example, at the top...
