Temperature Dependence of Double Layer Capacitance in Lithium-Ion Battery
Temperature plays an important role on the performance of a lithium-ion battery. The results of the experimental
study of the double layer capacitance were presented. The double layer capacitance in the cathode interface during discharging
process has been identified at wide range of temperatures from 50ºC to -20ºC from series of impedance measurements at
different state of charge conditions. Results proved that at higher temperatures, the cathodic double layer capacitance is higher
than at lower temperatures.
