Preparation of rambutan-like Co_0.5Ni_0.5Fe₂O₄ as anode for high-performance lithium-ion batteries.

ABSTRACT: NiFe₂O₄ is a kind of promising lithium ion battery (LIB) electrode material, but its commercial applications have been limited due to the electronic insulation property and large volume expansion during the conversion reaction process, which results in rapid capacity decrease and poor cycling stability. We synthesized rambutan-like Co_0.5Ni_0.5Fe₂O₄ using the self-templating solvothermal method. The special structure of Co_0.5Ni_0.5Fe₂O₄ which was formed by the assembly of numerous nanosheets could effectively buffer the volume change during the charging and discharging process. Partial substitution of Ni with Co. in NiFe₂O₄ leads to Co_0.5Ni_0.5
