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.
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.
