Abstract

Lithium-ion batteries are recognised as a key
technology to power electric vehicles and integrate gridconnected renewable energy resources. The economic viability
of these applications is affected by the battery degradation
during its lifetime. This study presents an extensive
experimental degradation data for lithium-ion battery cells
from three different manufactures (Sony, BYD and Samsung).
The Sony and BYD cells are of LFP chemistry while the
Samsung cell is of NMC. The capacity fade and resistance
increase of the battery cells are quantified due to calendar and
cycle aging. The charge level and the temperature are
considered as the main parameters to affect calendar aging
while the depth of discharge, current rate and temperature for
cycle aging. It is found that the Sony and BYD cells with LFP
chemistry has calendar capacity loss of nearly 5% and 8% after
30 months respectively. Moreover, the Samsung NMC cell
reached 80% state of health after 3000 cycles at 35C and 75%
discharge depth suggesting a better cycle life compared to the
other two battery cells with the same conditions.
