==BATTERY CELL, METHOD AND SYSTEM FOR MANUFACTURE SAME, BATTERY, AND POWER CONSUMING DEVICE - A simplified explanation of the abstract==


This abstract first appeared for US patent application 18520465 titled 'BATTERY CELL, METHOD AND SYSTEM FOR MANUFACTURE SAME, BATTERY, AND POWER CONSUMING DEVICE

==Simplified Explanation==

The patent application describes a battery cell with an electrode draw-out portion and an electrode assembly accommodated in the shell. The electrode assembly includes a first tab wound around a winding axis, with multiple turns of tab layers welded to form a first welded portion and some tab layers welded to the electrode draw-out portion to form a second welded portion.

* The battery cell includes a shell with an electrode draw-out portion.
* The electrode assembly has a first tab wound around a winding axis.
* Multiple turns of tab layers are welded to form a first welded portion.
* Some tab layers are welded to the electrode draw-out portion to form a second welded portion.
* At least one turn of tab layer connected to the first welded portion is not welded to the electrode draw-out portion.

== Potential Applications ==
This technology could be applied in various electronic devices that require efficient and reliable battery cells, such as smartphones, laptops, electric vehicles, and power tools.

== Problems Solved ==
This innovation solves the problem of ensuring secure connections between the electrode assembly and the electrode draw-out portion in a battery cell, improving the overall performance and safety of the battery.

== Possible Prior Art ==
One possible prior art could be the use of laser welding technology in battery cell manufacturing to create secure connections between components.


==Original Abstract Submitted==

A battery cell, a method and system for manufacturing the battery cell, a battery, and a power consuming device are disclosed. The battery cell includes: a shell including an electrode draw-out portion; and an electrode assembly accommodated in the shell. The end of the electrode assembly facing toward the electrode draw-out portion is provided with a first tab, the first tab is wound around a winding axis of the electrode assembly and includes a plurality of turns of tab layers, and at least some of the plurality of turns of tab layers are welded to form a first welded portion. Some of the plurality of turns of tab layers are welded to the electrode draw-out portion to form a second welded portion; and among the tab layers connected to the first welded portion, at least one turn of tab layer is not welded to the electrode draw-out portion.
