Nickel ferrite nanosheet aggregate material as well as preparation method and energy storage application thereof
The invention discloses a nickel ferrite nanosheet aggregate material as well as a preparation method and energy storage application thereof, and belongs to the field of functional nano materials and electrochemical energy storage. The material is formed by gathering nickel ferrite nanosheets with the thickness of 10-20 nm, electrochemical corrosion is conducted on Fe-Ni alloy in neutral electrolyte (ethyl alcohol and the like can be added to change the polarity of the Fe-Ni alloy), and further obtained Fe-Ni-based hydroxide precipitates are roasted in inert atmosphere, so that the material is obtained. And different microtopographies (such as a flower shape, a net shape, a ball-flower shape and the like) can be finally formed by regulating and controlling the types of the organic additives (such as a nonionic surfactant PVP, an anionic surfactant SDBS, a cationic surfactant CTAB and the like) in the electrolyte. The preparation method of the nanometer material provided by the invention is simple in process, environment-friendly and high in efficiency, and the prepared nickel ferrite nanosheet aggregate material can be used as a negative electrode of a lithium ion battery and shows excellent electrochemical performance..
