Carbon and silicon nanotubes and carbon and silicon nanocages as anodes in Li-ion battery and Mg-ion battery

In this work, the abilities and capacities of CNT(10, 0), SiNT(10, 0), C-70 and Si-70 as anodes in batteries are examined. The V-cell of nanomaterials (C-70, CNT(10, 0), Si-70, SiNT(10, 0)) and their N doped derivatives (N-C-70, N-CNT(10, 0), N-Si-70 and N-SiNT(10, 0)) on Li-ion batteries are 2.12, 2.16, 2.25, 2.30, 2.34, 2.39, 2.49 and 2.53 V. The V(cel)l and C-theory of nano-compounds as anodes in Mg-ion batteries are greater than other batteries, significantly. The C-theory of nanomaterials (C-70, CNT(10, 0), Si-70, SiNT(10, 0)) and their N doped derivatives (N-C-70, N-CNT(10, 0), N-Si-70 and N-SiNT(10, 0)) on Mg-ion batteries are 830, 846, 882, 899, 915, 934, 974 and 991 mAhg(-1). It can be concluded that the N-SiNT(10, 0) and N-CNT(10, 0) with the highest V-cell and C-theory are suitable anodes in batteries.
