The internal resistance of a lithium iron phosphate battery is mainly the resistance received during the insertion and extraction of lithium ions inside the battery, which reflects the difficulty of lithium ion conductive ions and electron transmission inside the battery.
In order to deeply analyze the influence of binder on the internal resistance of lithium iron phosphate battery, the compacted density, electrode resistance and electrode resistivity of the positive electrode plate prepared by three kinds of binders are compared and analyzed.
Therefore, the distribution state of the conductive agent and LiFePO 4 /C material has a great influence on improving the electrochemical performance of the electrode, and also plays a very important role in improving the internal resistance characteristics of lithium iron phosphate batteries.
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).
The intercept of the curve and the horizontal axis Z’ represent the ohmic resistance R1 of the battery, which is mainly attributed to the electrolyte, separator, and active material of the battery. The arc in the high-frequency region corresponds to the SEI impedance R2, which is mainly caused by the migration of lithium ions in the SEI film.
The results show that the internal resistance test of 14500 type whole cell prepared with PVDF, PAA/PVA and LA133 as the binder shows that the internal resistance of sample batteries LFP-F, LFP-AV and LFP-L are 40.5 mΩ, 33.2 mΩ and 35.7 mΩ, respectively. The internal resistance of the battery prepared by self-made PAA/PVA binder is the lowest.
