Another aspect of Lithium Ion Battery internal resistance is polarization resistance. This resistance arises due to the electrochemical processes occurring within the battery during charge and discharge cycles.
Internal resistance refers to the opposition to current flow within a battery cell itself. In LiFePO4 (Lithium Iron Phosphate) batteries, this resistance plays a pivotal role in determining the efficiency and overall performance of the battery. The internal resistance of a LiFePO4 battery can vary based on several factors:
Detecting the internal resistance of a lithium battery is an important part of maintaining and extending its life. As a professional lithium battery manufacturer, we understand the importance of obtaining accurate results quickly and efficiently.
However, the SOC has a higher influence on the internal resistance under low temperatures, because SOC affects the resistance value of the battery by influencing the disassembly and embedding speed of lithium ions in anode and cathode as well as the viscosity of electrolyte (Ahmed et al., 2015).
For example, a good internal resistance for a lead-acid battery is around 5 milliohms, while a lithium-ion battery’s resistance should be under 150 milliohms. What is the average internal resistance of a battery? The average internal resistance of a battery varies depending on the type and size of the battery.
Nie and Wu (2018) designed HPPC low temperature experiment for lithium iron phosphate battery. The least squares algorithm and the exponential fitting were used to construct the internal resistance model with SOC as the cubic polynomial and temperature as the exponential function.
