Document Type and Number:
WIPO Patent Application WO/2018/034463
Kind Code:
A1
Abstract:
The present invention relates to a battery cell comprising an insulator assembly. The present invention provides a battery cell characterized in that, when a needle-shaped conductor penetrates the insulator assembly, the part of the insulator assembly, into which a needle-shaped end of the needle-shaped conductor is introduced, is detached and penetrates an electrode assembly together with the needle-shaped conductor such that the detached part of the insulator assembly determines the planar shape of the penetrated opening of the electrode assembly.
