Abstract

In this paper, a new possible definition of failure zone for Li-ion batteries is proposed. Based on the general concept that a battery can be considered failed when its performance no longer meets the requirements of the application for which it is designed, a new application-dependent failure zone definition is proposed using the Ragone plot of the cell. The results of an experimental campaign to validate the proposal are presented and discussed in the paper.
