摘要：The accurate determination of the state-of-charge (SOC) of batteries is animportant element of battery management. One method to determine SOC is to
measure the voltage of the cell and exploiting the correlation between voltage and SOC.For electrodes with sloped charge/discharge profiles, this is a good method. However,for batteries with lithium iron phosphate (LFP) cathodes the charge/discharge profile isflat. Now, by using the materials and methods disclosed herein, an amount of cathodeactive material that has a sloped charge/discharge profile is mixed with LFP in a cathode,which results in a charge/discharge profile with enough slope that the SOC of the batterycan be determined by measuring the voltage alone.
