The internal resistance of square - shaped lithium - ion batteries is a crucial parameter that significantly affects their performance. It consists of ohmic resistance and polarization resistance.
Ohmic resistance mainly comes from the resistance of the battery's electrodes, electrolyte, and current collectors. For example, the material of the anode, often graphite, and the cathode, such as lithium - cobalt - oxide or lithium - iron - phosphate, has its own inherent resistivity. The thickness and conductivity of these electrode materials play a role in determining the ohmic resistance. A thicker electrode may have a higher resistance, while materials with better conductivity can reduce it. The electrolyte, which allows the movement of lithium ions between the electrodes, also contributes to the ohmic resistance. Low - viscosity and highly conductive electrolytes are preferred to minimize this part of the resistance.
Polarization resistance is related to the electrochemical reactions occurring at the electrode - electrolyte interfaces. During charging and discharging processes, the movement of lithium ions into and out of the electrodes creates a concentration gradient. This leads to a phenomenon called concentration polarization, which adds to the internal resistance. Charge - transfer polarization also exists, which is associated with the rate of the electrochemical reactions themselves. If the reaction kinetics are slow, the charge - transfer polarization resistance will be higher.
The internal resistance of square - shaped lithium - ion batteries has a direct impact on battery performance. A higher internal resistance means more energy is dissipated as heat during charging and discharging. This not only reduces the battery's energy efficiency but can also cause the battery to heat up, which may pose safety risks at high - current operation. In applications such as electric vehicles, where high - power discharge is required, a low - internal - resistance battery is essential to ensure efficient power delivery and a longer driving range.
