Ni2P/graphitic carbon nanostructure electrode with superior electrochemical performance

Electronic synergy to boost the performance of NiCoP-NWs@FeCoP-NSs anodes for flexible lithium-ion batteries

“…4a shows that two reduction peaks located at around 1.18 V and 1.49 V can be recorded in the initial cathodic scan, corresponding to the formation of the Li 3 P phase. [43][44][45] In addition, a small peak with low intensity located at 0.5 V can be observed, which corresponds to the formation of the solid electrolyte interphase (SEI) film and some irreversible reactions. 44,46 In the first anodic scan, the two obvious anodic peaks of 0.98 V and 1.18 V are considered to be the decomposition of the SEI film and the Li 3 P, and there is no shift in the subsequent scans.…”

Enhanced electrochemical performance of MoS2/graphene nanosheet nanocomposites

“…To determine the Li-ion conductivity of the samples as anodes, the GITT analysis was performed aer the 3 rd cycle. 44 Based on the diffusivity of Li + ion according to the state of charge (SOC), compared to MoS 2 -only, the MoS 2 /GNS composites exhibited overall improved ionic motion (Fig. 9a).…”

Synthesis and excellent performance of porous Ni 2 P @C/ CNTs nanocomposite derived from Ni‐MOFs as an anode for lithium‐ion batteries

“…Transition metal composites get special attention because of their various forms and variable valence states. 3 Especially, transition metal phosphides (TMPs) with low polarization resistance and discharge platforms enabled the performance of LIBs to be significantly improved and were promising for the next generation of LIBs anode materials. 4 Generally, sodium hypophosphite (NaH 2 PO 2 ) at around 250 C was used as inorganic phosphorus instead of PH 3 .…”
