abstract = {The applicability of heat generation data obtained after
cylindrical Li-ion cells discharging with a constant current
was analyzed thoroughly to determine cell degradation
mechanisms. Different commercial and noncommercial
cylindrical Li-ion cells, wherein graphite was used for
negative electrode creation, were considered in this study
and the degradation mechanisms were analyzed during cycling
and storage. The heat generation in the cylindrical cells
was estimated using heat flux and temperature measurements
of the cell surface. The results obtained using analysis of
the heat generation data were compared with those obtained
using differential voltage analysis. The use of the heat
generation data was shown to improve the detection and
separation of the degradation mechanisms in Li-ion batteries
during cycling and storage. The differential curve, which is
based on the heat generation data, was proposed to
investigate the degradation mechanisms. Moreover, the
effects of the C-rate current and temperature on the form of
the proposed differential curve were evaluated.},
