Additional factors

Temperature and environmental temperature are important factors affecting the resistance. For lithium-ion batteries, the temperature affects the activity of electrochemical materials, which directly determines the speed of electrochemical reaction and the speed of ion movement.

On the one hand, the current is directly related to the polarization resistance. The general trend is that the greater the current, the greater the polarization resistance. On the other hand, the thermal effect of current affects the activity of electrochemical materials.

Battery self factors

The difficulty of intercalation and de intercalation of cathode material, anode material and lithium ion determines the internal resistance of the material, which is a part of the concentration polarization resistance.

Electrolyte, the movement rate of lithium ion in electrolyte, affected by the conductivity of electrolyte, is an important part of electrochemical polarization resistance.

The diaphragm and its resistance directly form a part of the ohmic internal resistance. At the same time, it hinders the movement rate of lithium ion and forms a part of the electrochemical polarization resistance.

The collector resistance, the component connection resistance, is an important part of the battery ohmic internal resistance.

The level of technology, the manufacturing process of the electrode, the uniformity of the coating, and the compaction density will also have a direct impact on the polarization resistance.
