Abstract

A fast-charging battery cell, a lithium-ion battery, and an electric product are disclosed, which relates to the field of new energy technology. In the fast-charging battery cell provided, the positive electrode is provided with positive electrode coating gaps, and the negative electrode is provided with negative electrode coating gaps. By optimizing the positions of the positive electrode coating gaps and negative electrode coating gaps, the ability of the negative electrode to accept lithium ions is enhanced, the increase in side reactions is minimized and the pressure at the corners is alleviated. As a result, the rate performance and cycling performance of the fast-charging battery cell are enhanced. A lithium-ion battery and an electric product comprising the above fast-charging battery cell are also provided.
