Abstract
Provided include a single winding core, a lithium cell with a single winding core, and a successive winding method of a single winding core, where a positive area on a surface of a positive plate corresponds to a negative area on a surface of a negative plate of the single winding core; a plurality of positive tabs and a plurality of negative tabs are respectively disposed at one side of the positive plate and the negative plate, and the negative tabs and the positive tabs are arranged to be interlaced with each other. Thereby, after the positive plate, a first isolation film, the negative plate, and a second isolation film are sequentially stacked and then successively wound, the positive tabs and negative tabs respectively form a positive and a negative tab groups, rendering the single winding core capable of high-current discharge.
