WINDING NEEDLE SLEEVE, BATTERY UNIT, BATTERY, POWER CONSUMING DEVICE, AND WINDING DEVICE - A simplified explanation of the abstract
- This abstract for appeared for US patent application number 18331598 Titled 'WINDING NEEDLE SLEEVE, BATTERY UNIT, BATTERY, POWER CONSUMING DEVICE, AND WINDING DEVICE'
Simplified Explanation
The present application describes a winding needle sleeve, battery unit, battery, power-consuming device, and winding device. The winding needle sleeve has a through slot that allows for radial expansion or contraction. This solves the problem in the prior art where an electrode assembly collapses, leading to wrinkling of the electrode assembly's surface and lithium deposition, which can be a safety hazard.
Original Abstract Submitted
The present application discloses a winding needle sleeve, a battery unit, a battery, a power-consuming device and a winding device. A wall of the winding needle sleeve is provided with a through slot extending through the wall. The through slot extends from one end to the other end of the winding needle sleeve, so as to allow expansion or contraction of the winding needle sleeve in a radial direction. The technical solution provided by the present application can solve the problem in the prior art that an electrode assembly collapses due to expansion and contraction thereof, resulting in wrinkling of a surface of the electrode assembly and the phenomenon of lithium deposition, thus causing potential safety hazards.
