In this paper, the lithium iron phosphate battery capacity increment curve (IC curve) was used as the analysis tool and the IC curve obtained by SOC-OCV was selected as the reference curve and the IC curves of the same batch in the battery pack are selected and compared with the reference curve.
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.
Nie and Wu (2018) designed HPPC low temperature experiment for lithium iron phosphate battery. The least squares algorithm and the exponential fitting were used to construct the internal resistance model with SOC as the cubic polynomial and temperature as the exponential function.
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.
From this comparison, it can be clearly found that the migration energy barrier of lithium ions after carbon coating is reduced, which is conducive to improving the transport of lithium ions, thereby reducing the internal resistance of lithium iron phosphate batteries. First, prepare PVA hydrogel for later use.
In order to further reduce the internal resistance of the battery prepared by the traditional LiFePO 4 /C battery process, the PAA/PVA blending water binder was prepared.
