6 FAQs about [Lithium iron phosphate battery internal resistance principle diagram]

How does SoC affect the internal resistance of a lithium ion battery?

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).

What factors affect the internal resistance of a battery?

The internal resistance of battery is affected by multiple factors (state of charge, temperature, discharge rate etc.). Ahmed et al. (2015) analyzed the internal resistance of battery by the impedance spectroscopy, and they found that the internal resistance of the LIBs was related to the temperature and state of charge (SOC).
