Problems solved by technology
Traditional soft-packed batteries generally use strip-shaped rigid tabs as electrode conductive leads. The width of the rigid tabs is relatively wide, so that the size of the battery is limited by the width of the tabs, and the size of the battery cannot be adjusted. Smaller, which in turn affects the size of the Bluetooth headset

The invention discloses a flexibly-packaged battery cell capable of outputting lead packaging in any direction. The flexibly-packaged battery cell comprises a first pole piece, a diaphragm and a second pole piece which are stacked in sequence, the first pole piece, the diaphragm and the second pole piece are wound to form a winding body, the winding body is arranged in an inner cavity of an aluminum-plastic film shell in a sealing manner, and the inner cavity of the aluminum-plastic film shell is filled with electrolyte; and electrode conductive leading-out bodies are installed at any positions of sheet bodies of the first pole piece and the second pole piece, the electrode conductive leading-out bodies are flexible electric conductors, and the flexible electric conductors penetrate out ofthe aluminum-plastic film shell in any direction. According to the invention, the traditional positive and negative tabs are replaced by the flexible conductors, so that the space of the battery cellis greatly saved, the lead packaging can be carried out in any direction, the problem of PACK assembling and wire adding is solved, and the market requirements are met.
Description
technical field [0001] The invention belongs to the technical field of soft-packed electric cores, and specifically relates to a soft-packed electric core packaged with wires from any orientation. Background technique [0002] Soft-pack batteries are commonly used power batteries in the industry. Soft-pack batteries are easy to use and widely used, especially as tiny batteries. [0003] However, the current TWS Bluetooth battery is required to be smaller and smaller in size as the market requires the size of the Bluetooth headset to be smaller and smaller. Traditional soft-packed batteries generally use strip-shaped rigid tabs as electrode conductive leads. The width of the rigid tabs is relatively wide, so that the size of the battery is limited by the width of the tabs, and the size of the battery cannot be adjusted. Smaller, which in turn affects the size of the Bluetooth headset. Contents of the invention [0004] The object of the present invention is to provide a s...
