The mechanism for the conductivity and charging/discharging parameters of the battery has been performed to investigate the performance of the CR2016 coin cell battery, which includes the characteristics of resistance, electrical conductivity as well as the charging and discharging mechanisms of LiFe0.09Gd0.01PO4/C, Lithium Metal Anode (Li), LiPF6 Electrolyte, Polypropylene (PP) membrane separator, and PVDF/NMP active ingredient. A standard deviation (SD) value of 1% with a range of electrical conductivity of 2.2 x 10-2 S/cm -2.4 x 10-2 S/cm was obtained based on the measurements of 8-coin cell battery samples. The highest material charging capacity value was obtained as 125 mAh/g in the 10th cycle and has a lithium diffusion (DLi) of 2.33 x 10-7 S/cm2 .
