Tin-based materials supported on nitrogen-doped reduced graphene oxide towards their application in lithium-ion batteries

“…The results have generally been promising towards the improvement of their specic capacity and cycling stability. 8,[18][19][20] To further enhance the properties of rGO, element (such as sulfur, boron, and nitrogen) doping via chemical substitution has been used beyond just morphology and size control, and nitrogen doping is shown to be particularly effective in modulating the electronic properties of graphene. 21 Based on previous reports on Sn-based materials supported on rGO or nitrogen-doped rGO (N-rGO), the most frequently used preparation method is to use rGO as a template and subsequently subject it to a reduction reaction to form Snbased rGO composites.…”

A Low-Cost and High-Capacity SiOx/C@graphite Hybrid as an Advanced Anode for High-Power Lithium-Ion Batteries

“…The diameter of the semicircle in the high-frequency region is related to the contact resistance ( R s ) of the electrolyte and the electrode. 51 , 52 The diameter of the oblate semicircle in the intermediate-frequency region corresponds to the SEI film impedance ( R SEI ) and the charge-transfer impedance at the interface between the electrode and the electrolyte ( R CT ), and the oblique part of the low-frequency region is related to the solid-phase diffusion ( Z W ) ability of lithium ions in the electrode also known as the Warburg impedance. 53 , 54 It can be clearly discerned that the diameter of the semicircle of the SCG-1100 hybrid is the smallest than that of pure SC, SCG-900, and SCG-1300, showing that the charge-transfer resistance of SCG-1100 is the smallest.…”
