Abstract
Provided are an apparatus and method of obtaining degradation information of a lithium ion battery cell. The apparatus according to an embodiment estimates a first positive electrode usage region related to a first state of health of the lithium ion battery cell. The apparatus estimates a second positive electrode usage region related to a second state of health of the lithium ion battery cell. Then, the apparatus calculates an amount of change of maximum storage capacity of a positive electrode of the lithium ion battery cell with respect to a usage period from the first state of health to the second state of health, based on the first positive electrode usage region and the second positive electrode usage region.
