Embodiment 1

[0082] ginseng Figure 5 , the battery 100 includes a cell 10 , a first protection body 20 , a second protection body 30 and a third protection body 40 .

[0083] The first protection body 20 covers the top surface 101 . The second protection body 30 covers edges of the first region 1021 and the second region 1022 of the bottom surface 102 . The third protection body 40 covers the first edge region 1032 and the second edge region 1042 . Wherein, the third protection body 40 is connected between the first protection body 20 and the second protection body 30 to form a grid structure for protecting the electric core 10 .

Embodiment 2

[0085] ginseng Figure 6 The difference between Embodiment 2 and Embodiment 1 is that the battery 100 in Embodiment 2 further includes a first protection portion 50 and a second protection portion 60 . The first protection portion 50 covers the edge of the first side 103 close to the top surface 101 and the edge of the second side 104 close to the top surface 101 . The second protection portion 60 covers the edge of the first side 103 close to the bottom 102 and the edge of the second side 104 close to the bottom 102 . Wherein, the first protection part 50 connects the first protection body 20 and the third protection body 40 , and the second protection part 60 connects the second protection body 30 and the third protection body 40 .

Embodiment 3

[0087] ginseng image 3 The difference between embodiment 3 and embodiment 2 is that the third protective body 40 in embodiment 3 further covers the first middle region 1031 and the second middle region 1041 . That is, the third protective body 40 in the second embodiment completely covers the first side 103 and the second side 104 .

Abstract

A battery comprises a battery cell, a first protection body, a second protection body and a third protection body. The battery cell comprises a top surface, a bottom surface back to the top surface, two first side surfaces arranged back to back and two second side surfaces arranged back to back. The two first side surfaces are connected with the two second side surfaces, and the two first side surfaces and the two second side surfaces are respectively connected between the top surface and the bottom surface. The first side face comprises a first middle area and first edge areas located on the two sides of the first middle area respectively, and the second side face comprises a second middle area and second edge areas located on the two sides of the second middle area respectively. The first protection body covers the top surface, the second protection body covers part or all of the bottom surface, and the third protection body covers the first edge area and the second edge area. The third protection body is connected between the first protection body and the second protection body. The invention also provides a manufacturing method of the battery.

Description

technical field [0001] The present application relates to the battery field, in particular to a battery and a manufacturing method thereof. Background technique [0002] In the field of soft-pack lithium batteries, cell packaging has always been a major issue facing the industry. Especially for the large-capacity lithium battery products developed in recent years, due to the special requirements for battery capacity, the battery cells need to develop towards large thickness and irregular shape, which brings challenges to the design and manufacture of battery cells. In the process of cell packaging, in order to ensure the electrical connection of the cell, the positive and negative tabs are usually drawn out from the winding layer of the cell, and extend out of the aluminum-plastic film package of the cell for a certain length, and then cut by shaping Finally, weld it with the PCM board (protection board) to realize the electrical connection between the PCM board and the cel...
