Different synthesis of Mn_xCo_yNi_zCO_3 microspheres as new anode material for lithium ion battery

摘要

AbstractThe Mn0.629Co0.141Ni0.230CO3@C (using ethylene glycol as solvent) and Mn0.756Co0.133Ni0.111CO3(using H2O as solvent) with morphology of microspheres were synthesized respectively by solvothermal and hydrothermal method respectively. The Mn0.629Co0.141Ni0.230CO3@C behaved outstanding electrochemical performances as an anode material. It had a high initial capacity (1322 mAhg−1) and its reversible discharge specific capacity could maintain at 846 mAhg−1after 200 cycles under current density of 100 mA g−1in the voltage range of 0.01–3 V. The reasons for different solvents on electrochemical properties of expected compound were presented also. The ternary manganese–nickel–cobalt carbonate (Mn0.629Co0.141Ni0.230CO3@C) synthesized by solvothermal method could be used as novel anode materials for lithium-ion battery application.
