One-pot solvothermal process is adopted to develop, 3D hierarchical Fe3O4 nanoparticles supported 2D reduced graphene oxide sheets (Fe3O4/r-GO) as possible negative electrodes for lithium ion batteries. The synthesis parameters are optimized to prepare agglomeration-free Fe3O4 nanostructures with uniform size and shape on r- GO. The field emission ...
The long-term cycle performance of NCM811/Li batteries at high temperature was achieved by mixing LiDFOB and LiPF(6)salts into the ethylene carbonate (EC) and ethyl methyl carbonate (EMC) solution (EC/EMC = 3:7 by volume). The differential scanning calorimeter (DSC) and thermogravimetric analysis (TGA) tests indicate 0.8 M LiPF6/0.2 M LiDFOB electr...
Nickel cobalt sulfides are deemed as promising electrode materials for energy storage devices due to their rich redox active sites as well as superior conductivity. Herein, we report P-doped Ni-Co-S@C (PNCS@C) assemblies consisting of many nanosheets through facile one-step solvothermal route and a subsequent phosphorization process. The as-obtaine...

The direct preparation of LiNi0.8Co0.1Mn0.1O2 (LNCM811) cathode materials from the hydrochloric acid leaching of laterite are promising; however, there are Cl- ions and other impurities in the hydrochloric acid leaching solution, thereby limiting the commercial application of LNCM811. In this study, we compared the LNCM811 prepared from Cl-- and SO...

The design and synthesis of hierarchical micro-nano structures of transition metal oxides have played an essential role in the supercapacitor field. In this work, in situ three-dimensional construction of nanoporous cobalt oxide (Co3O4) has been derived from the metal-organic framework (MOF) distributed evenly in electrospun polyacrylonitrile nanof...
