Document Type and Number:
WIPO Patent Application WO/2021/023010
Kind Code:
A1
Abstract:
A splicedly formed lithium strip, a preparation method therefor, and a negative pole (52), lithium ion battery (5), battery module (4), battery pack (1) and apparatus related thereto. The splicedly formed lithium strip is formed by splicing two or more base lithium strips to each other, wherein fluctuations in the thicknesses of the base lithium strips are 5% or less. The splicedly formed lithium strip has a splicing region and a non-splicing region that are alternatingly distributed along the splicing direction, and the maximum thickness H of the splicing region and the minimum thickness L of the non-splicing region satisfy (I).
