“…For example, Eq. 8 fitted to the data at 0% SOC (fully discharged state) resulted in Z Im ϭ 0.1311 Ϫ 0.1204Z Re ϩ 0.0363Z 2 Re . By taking the slope of this function at each data point and solving Eq.…”

“…As alternative materials to replace lithium metal, graphite, pyrolytic carbon, mesophase carbon, carbon fiber, as well as carbons doped with P and N, have been studied extensively. [1][2][3][4][5][6][7][8] However, the lithium ion transport properties in these carbons have not been measured precisely due to experimental difficulties associated with the changes of lithium content with time during charging and discharging the electrode, and from uncertainties in the determination of the parameters necessary for evaluation of the lithium ion diffusion coefficient. These parameters include the dependence of the open-circuit potential of the anode upon the lithium content, the electrochemically active surface area, and the molar volume of the lithiated material.…”

A complex impedance model for spherical particles was used to determine the lithium ion diffusion coefficient in graphite as a function of the state of charge (SOC) and temperature. The values obtained range from of 1.12 ϫ 10 Ϫ10 to 6.51 ϫ 10 Ϫ11 cm 2 /s at 25ЊC for 0 and 30% SOC, respectively, and for 0% SOC, the value at 55ЊC was 1.35 ϫ 10 Ϫ10 cm 2 /s. The conventional potentiostatic intermittent titration technique (PITT) and Warburg impedance approaches were also evaluated, and the advantages and disadvantages of these techniques were exposed.

“…The enhanced electrochemical lithium storage properties registered for BC 4 N with respect to BC 2 N are attributed to the increased amount of carbon content in the BC 4 N material, which is 65 wt % with respect to 45 wt % present within the BC 2 N structure. It has been already reported in previous studies that increasing carbon content in BCN-based anodes increases the electrochemical lithium storage capacities [40]. Raman investigation also reveals significant changes in the structure of the materials, namely, a much higher lateral cluster size, La = 10.3 nm, found for the BC 4 N material.…”

“…Ishikawa et al [40] was the first to explore BCxN, systems (x =~3, 7, 19) as anode materials, and found that storage capacity increases with an increase in the carbon content. The observed capacities were in the range of 180 mAh¨g´1 for the studied materials.…”

“…Nevertheless, heteroatom substitution in carbonaceous material is found to improve the electrochemical performance towards lithium storage. Doping with nitrogen or boron is an interesting approach to enhancing the performance of carbon-based anodes [39][40][41][42]. Boron-doped carbon has been reported to improve reversible Li storage capacity compared to pristine materials [43].…”

Amorphous BCN ceramics were synthesized via a thermal conversion procedure of piperazine-borane and pyridine-borane. The synthesized BC 2 N and BC 4 N ceramics contained, in their final amorphous structure, 45 and 65 wt % of carbon, respectively. Elemental analysis revealed 45 and 65 wt % of carbon for BC 2 N and BC 4 N, respectively. Transmission electron microscopy (TEM) and X-ray diffraction (XRD) confirmed the amorphous nature of studied compounds. Lateral cluster size of carbon crystallites of 7.43 and 10.3 nm for BC 2 N and BC 4 N, respectively, was calculated from Raman spectroscopy data. This signified a higher order of the carbon phase present in BC 4 N. The electrochemical investigation of the low carbon BC 2 N composition as anodes for Li-ion batteries revealed initial capacities of 667 and 235 mAh¨g´1 for lithium insertion/extraction, respectively. The material with higher carbon content, BC 4 N, disclosed better reversible lithium storage properties. Initial capacities of 1030 and 737 mAh¨g´1 for lithium insertion and extraction were recovered for carbon-rich BC 4 N composition. Extended cycling with high currents up to 2 C/2 D revealed the cycling stability of BC 4 N electrodes. Cycling for more than 75 cycles at constant current rates showed a stable electrochemical behavior of BC 4 N anodes with capacities as high as 500 mAh¨g´1.
