“…Each spectrum shows a semicircle high frequency range, which describes the charge transfer resistance (R ct ) for these electrodes [54,55]; and a slop line in the low frequency represents sodium ion diffusion resistance in the bulk of the active material [56,57]. The ohmic resistance (R s ) is related to the resistance of electrolyte and particles contact [58], and constant phase element (CPE) is denoted as the double layer capacitance [59]. The corresponding fitting parameters are given in Table 1.…”

“…From the initial discharge curves (Fig. 3A), all the samples had a typical ~3.4 V voltage platform, which was corresponding to reduction reaction 5 based on the couple of Fe 2+ /Fe 3+ during lithium-ion insertion process. In addition, the LiNi 0.02 Fe 0.08 PO 4 /C sample displayed a highest capacity of 162.2 mAh g -1 among all of the samples.…”

“…Several lithium transition metal oxides, such as layered LiCoO 2 , LiNi 1/3 Co 1/3 Mn 1/3 O 2 , spinel LiMn 2 O 4 , 15 and olivine LiFePO 4 , have been commercially used in lithium ion batteries. Among them, olivine LiFePO 4 has attracted considerable attention as perspective intercalation cathode material for lithium-ion batteries due to its inherent merits such as long cyclability, high safety, low toxicity, and potential low cost [4][5][6]. However, olivine LiFePO 4 has an intrinsically poor electrical and ionic conductivity, seriously affecting 20 its electrochemical performance and limiting its large-scale application [7][8][9].…”

The LiNi x Fe 1-x PO 4 /C (x=0.00, 0.01, 0.02, 0.03, 0.04), LiMn y Fe 1-y PO 4 /C (y=0.00, 0.01, 0.02, 0.03, 0.04) and LiNi 0.02 Mn 0.03 FePO 4 composites have been successfully synthesized by a simple solid-state method. The structure, morphology 10 and electrochemical property of the as-prepared materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and charge/discharge tests. The XRD patterns indicate that doping with Ni 2+ or Mn 2+ do not affect the structure of olivine LiFePO 4 . The results of electrochemical performance measurements reveal 15 that the LiNi 0.02 Fe 0.98 PO 4 /C shows the best electrochemical performance among all of the single Ni-doped samples. Meanwhile, comparing with other single Mn-doped materials, the LiMn 0.03 Fe 0.97 PO 4 /C show the highest initial discharge capacity and excellent cyclic stability. In order to further improve the electrochemical performance of LiFePO 4 /C, LiNi 0.02 Mn 0.03 Fe 0.95 PO 4 /C composite with Ni and Mn co-doping was 20 also synthesized by the same route. Relative to other samples, the  Corresponding author: Xianyou Wang. 2 LiNi 0.02 Mn 0.03 Fe 0.95 PO 4 /C delivers higher initial discharge capacity of 164.3 mAh g -1 at a rate of 0.1 C. Moreover, it also exhibits excellent cyclic stability with capacity retention of 98.7% cycled at 1 C after 100 cycles. CV shows that the Ni and Mn dual-doping reduce the electrode polarization, which may be the important factors for improving the electrochemical properties of the cathode materials.5
