Document Type and Number:
WIPO Patent Application WO/2024/082270
Kind Code:
A1
Abstract:
The present application discloses a battery cell, a battery and an electrical device. The battery cell comprises a first pole piece and a second pole piece. The first pole piece and the second pole piece are arranged opposite to each other. The first pole piece or the second pole piece has a thinning region, and an adsorbent (4) is arranged at a position corresponding to the thinning region. The adsorbent (4) can fill a gap between the first pole piece and the second pole piece due to the presence of the thinning region and can further adsorb an electrolyte, such that normal lithium ion transmission can be achieved between the first pole piece and the second pole piece, thereby preventing the phenomenon of purple spots or lithium precipitation of the pole pieces and effectively improving the cycle performance and the safety performance of a battery.
