Title: Facile synthesis of fusiform layered oxides assisted by microwave as cathode material for lithium-ion batteries

Abstract

Graphical abstract: Fusiform layered oxides synthesized by microwave solvothermal reaction with excellent electrochemical property as cathode material for lithium-ion batteries. - Highlights: • LiMn{sub 0.25}Ni{sub 0.5}Co{sub 0.25}O{sub 2} is obtained by microwave solvothermal reaction. • Material synthesized at 800 °C exhibits fusiform hierarchical morphology. • High initial discharge capacity of 183 mAh g{sup −1} is reached at 0.1C. • 154 mAh g{sup −1} is remained with a capacity retention of 84.2% after 100 cycles. • Excellent rate capability is also obtained. - Abstract: A facile microwave solvothermal reaction is performed to synthesize novel LiMn{sub 0.25}Ni{sub 0.5}Co{sub 0.25}O{sub 2} ternary layered oxide with 1 D fusiform morphology. Scanning electron microscopy (SEM) images show that material synthesized at 800 °C well keeps the fusiform morphology of the precursor with a particle size of 100–300 nm. All the three elements are perfectly dispersed and a well-formed layered structure is obtained. Thus, good electrochemical performances with high initial discharge capacity of 183 mAh g{sup −1} is reached. Furthermore, high discharge capacity of 154 mAh g{sup −1} is remained with a capacity retention of 84.2% after 100 cycles at 20 mA g{sup −1}. Excellent rate capability is also obtained with high discharge capacity of 99more » mAh g{sup −1} at 2000 mA g{sup −1}. It seems such facile microwave solvothermal method is one of the most promising candidates for preparing ternary layered oxides with excellent electrochemical properties as cathode material for lithium ion batteries.« less
