Li-NMC battery internal resistance at wide range of temperature

One of the factors that affects energy transfer by Lithium-ion batteries is internal resistance. This internal resistance occurs due to resistivity of the electrochemical materials and its ionic component. Meanwhile, the internal resistance of a battery is affected by several factors such as tempera...

The objective of this study is to provide the data of battery internal resistance at a wide temperature range up to 80°C.
