What is internal resistance in a battery?

Internal resistance is the opposition within a battery that impedes electric current flow. It is an intrinsic property influenced by the battery's materials, design, and operating conditions. When current flows through a lithium battery, internal resistance generates heat and causes a voltage drop, directly impacting efficiency and performance.

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).
