Abstract

Here, electro-chemical properties of BN and BP nanocages as anodes in metal-ion batteries are examined. The effect of halogens adoption of BN and BP-NCs on electro-chemical properties of M-IBs are investigated. Results showed that the BP nanocages as anode electrode in M-IBs has higher efficiency than BN nanocages and the K-IB has higher cell voltage than N-IBs. Results indicated that the halogens adoption of BN and BP-NCs are improved the cell voltage of M-IBs. Results proved that the F-doped M-IBs have higher cell voltage than M-IBs. Finally, F-B17P18 as anodes in K-IB is proposed as suitable electrodes.

Highlights

  • In previous studies, the chemical and physical properties of boron nitride nanocages (BN-NC) and boron phosphide nanocages (BP-NC) have been i­nvestigated[1,2,3]

  • The potential of graphite, nanotubes and nanocages as anodes of metal-ion batteries (M-IBs) have been studied and results showed that nanocages have higher potential rather graphite and n­ anotubes[16,17,18]

  • The electronic properties of B­ 16N16, ­B16P16 and ­B7C24P are examined and and results indicated that the electro-chemical properties of BN nanocages are improved by increasing the size of ­rigs[22,23]

Summary

Introduction

The chemical and physical properties of boron nitride nanocages (BN-NC) and boron phosphide nanocages (BP-NC) have been i­nvestigated[1,2,3]. Results of previous studies indicated that the halogen (F, Cl and Br) adoption of nanocages are decreased the band gap energies of nanocages and halogen (F, Cl and Br) adoption are improved the electro-chemical properties (cell voltage) of nanocages as anodes and cathode materials in ­batteries[12,13,14,15]. The metal adsorption on BN-NCs are investigated and results indicated that the lithium and potassium atoms are increased the properties of NC in M-IBs. The electronic properties of B­ 16N16, ­B16P16 and ­B7C24P are examined and and results indicated that the electro-chemical properties (cell voltage) of BN nanocages are improved by increasing the size of ­rigs[22,23]. They demonstrated that storage capacities of B­ 18N18 and B­ 18P18 in L-IBs are 893 and 795 mAh/g and they showed that ­Vcell of F-doped B­ 18N18 and ­B18P18 are higher than Br-doped MIBs by theoretical calculation
