Embodiment 1

[0016] refer to figure 2 , shows a schematic structural diagram of a battery cell according to Embodiment 1 of the present invention.

[0017] like figure 2 As shown, the battery cell in the embodiment of the present invention includes: bidirectional lead-out terminals, that is, a pair of first electrode lead-out terminals and a pair of second electrode lead-out terminals. Wherein, the first electrode lead-out terminal pair includes a first positive terminal 201 and a first negative terminal 202 , and the second electrode lead-out terminal pair includes a second positive terminal 203 and a second negative terminal 204 .

[0018] The first positive terminal 201 and the first negative terminal 202 are arranged side by side, and the second positive terminal 203 and the second negative terminal 204 are arranged side by side; The negative terminals 204 are oppositely disposed.

[0019] For the battery cell provided by the embodiment of the present invention, in actual use, a p...

Embodiment 2

[0022] refer to image 3 , shows a schematic diagram of the connection of the battery cell in the terminal according to Embodiment 2 of the present invention.

[0023] The battery cell in the embodiment of the present invention has the same structure as the battery cell in the first embodiment, and also includes bidirectional lead-out terminals, that is, a pair of first electrode lead-out terminals and a pair of second electrode lead-out terminals. Wherein, the first electrode lead-out terminal pair includes a first positive terminal and a first negative terminal, and the second electrode lead-out terminal pair includes a second positive terminal and a second negative terminal. The first positive terminal and the first negative terminal are arranged side by side, the second positive terminal and the second negative terminal 204 are arranged side by side; the first positive terminal 201 and the second positive terminal 203 are arranged oppositely, and the first negative termina...

Abstract

The invention provides a battery core. The battery core comprises a first electrode leading-out terminal pair and a second electrode leading-out terminal pair; wherein, the first electrode leading-out terminal pair comprises a first positive terminal and a first negative terminal, the second electrode leading-out terminal pair comprises a second positive terminal and a second negative terminal; the first positive terminal and the first negative terminal are arranged side by side, the second positive terminal and the second negative terminal are arranged side by side; the first positive terminal and the second positive terminal are arranged oppositely, and the first negative terminal and the second negative terminal are arranged oppositely. Through the battery core provided by the invention, a series of problems that FPC is required for connecting a charge port or a main board with the electrode of the battery core in the prior art can be avoided.

Description

technical field [0001] The invention relates to the technical field of mobile terminals, in particular to a battery cell. Background technique [0002] attached figure 1 It is a schematic diagram of the structure diagram of the battery cell of the lithium-ion battery used on the existing terminal. like figure 1 As shown, the existing battery cells have a pair of electrode lead-out terminals, specifically including a positive terminal 101 and a negative terminal 102 . Both charging and discharging of the battery cell need to enter and exit the battery cell through the pair of electrode lead-out terminals. Since the lead-out terminals of the electrodes contained in the battery cell are fixed in position, after the battery cell is packaged, the connection position of the battery is also relatively fixed. [0003] At present, fast charging has become a common demand for terminals, and fast charging requires that the impedance of the charging path be as small as possible, and...
