Description
Technical Field
The invention belongs to the technical field of soft-package battery cells, and particularly relates to a soft-package battery cell with a lead packaged in any direction.
Background
The soft package battery core is a power supply battery core commonly used in the industry, is convenient to use and has wide application range, and particularly has more advantages when being used as a small battery.
However, the size of the existing TWS bluetooth battery cell is required to be smaller and smaller under the condition that the size of the bluetooth headset is required to be smaller and smaller by the market, and the size of the battery assembled in the headset is required to be smaller and smaller correspondingly. Traditional soft-packaged electrical core generally all adopts banding rigidity utmost point ear as the electrically conductive extraction body of electrode, and the width broad of rigidity utmost point ear just so makes the size of electric core receive the restriction that receives utmost point ear width, can't do the size of electric core for a short time, and then has influenced bluetooth headset's volume.
Disclosure of Invention
The invention aims to: in order to solve the problems, a soft package battery cell with a wire package at any position is provided.
The technical scheme adopted by the invention is as follows: a soft package battery cell with a lead package at any position comprises a first pole piece, a diaphragm and a second pole piece which are sequentially stacked, wherein the first pole piece, the diaphragm and the second pole piece are wound to form a winding body, the winding body package is arranged in an inner cavity of an aluminum-plastic film shell, and electrolyte is filled in the inner cavity of the aluminum-plastic film shell; and electrode conductive leading-out bodies are arranged at any positions on the body of the first pole piece and the second pole piece, the electrode conductive leading-out bodies are flexible conductors, and the flexible conductors penetrate out of the aluminum plastic film shell from any direction.
Preferably, the winding body is circular, oval or square.
Preferably, the aluminum-plastic film shell is made by punching an aluminum-plastic film by using a shell punching machine.
Preferably, the first pole piece and the second pole piece are a positive pole piece and a negative pole piece respectively.
Preferably, the flexible conductor is welded on the pole piece by adopting a sheet making machine or an all-in-one machine welding head.
Preferably, the flexible electric conductor adopts a lead or a flexible tab.
In addition, the invention also discloses a battery made of the soft package battery cell packaged by the lead at any position. After the battery is folded, the size of the battery in the diameter direction is reduced, and when the battery is actually used, a lead does not need to be welded.
The invention has the advantages that the electrode conductive lead-out body of the traditional soft-package battery cell is improved from a rigid structure to a soft or flexible structure, and better flexibility is provided for the design volume of the soft-package battery cell, so that the requirement of electronic equipment on the size and the size of the volume of the soft-package battery cell is ensured, and the soft-package battery cell is particularly suitable for the battery cell of a Bluetooth earphone.
The flexible electric conductor is used for replacing a traditional electric core tab structure, the outgoing direction is free, the outgoing position is free, the installation is convenient, the flexibility is good, and the problem that the battery needs to be connected with a wire when being assembled in a PACK (picture archiving and communication system) is solved.
In summary, due to the adoption of the technical scheme, the invention has the beneficial effects that: in the invention, the flexible electric conductor is adopted to replace the traditional positive and negative electrode lugs, so that the space of the battery cell is greatly saved, the lead package can be taken out from any position, the problem of wire adding of PACK assembly is solved, and the market demand is met.
