Abstract

A battery construction is disclosed having improved safety behaviour under conditions of mechanical abuse, in particular crush type abuse, wherein an additional site for internal short circuiting is engineered therein. In certain circumstances, it can be beneficial to initiate the engineered short before other internal shorts occur. Additionally, it may be beneficial for the engineered short to have a lower resistance than the internal resistance of the battery. The invention is particularly suited for application in lithium ion type batteries.
