Battery cell having electrode splintering

2016 
The invention relates to a battery cell, in particular a lithium-ion cell in which in at least one electrode is a pressure-sensitive layer is integrated, which has internal stresses in such a way that this at least one electrode upon application of a pre-defined, especially punctiform force and / or is divided on penetration of a foreign body in the battery cell in a plurality of non-electrically connected portions and thus a short circuit is prevented or eliminated.
