The XRD patterns of the samples exhibit that the main phase is LiFePO4 with minor impurity phases of PbO and Fe2O3 in the structure, in which the phase ratio of PbO increases with increasing doping content. Four probe electrical resistance measurements showed that resistance decreases from 111 kO to 37 kO when increasing Pb-content; however, CV measurement indicated that redox peak wideness increased for x = 0.09, unwanted behavior for the battery cells. The galvanostatic cycles at C/2-rate yielded the highest capacity value of 121.6 mAh/g at room conditions with 1.06% capacity fade over 100 cycles when using x = 0 0.06 sample-better than undoped cells-while C-rate tests confirmed promising results for LiFePO4 cells using same sample concentration level.eninfo:eu-repo/semantics/closedAccessCathode MaterialRechargeable LithiumIonCarbonZincBatteriesNiArticle342610.1007/s10854-023-11199-82-s2.0-85170639149Q2WOS:001068202500002Q2
