Embodiment 1
[0025] Add 4.5g of ferric chloride hexahydrate, 12g of sodium acetate and 3.3g of polyethylene glycol into 160ml of ethylene glycol, and ultrasonically oscillate for 30 minutes to obtain a uniform mixed solution; The reaction was carried out for 12 hours. The hydrothermal product was successively cleaned by centrifugation with deionized water and absolute ethanol, and after vacuum freeze-drying at a temperature of -60°C and a pressure of 0 kPa for 6 hours, the product was obtained; ℃ for 8 hours, and cooled to room temperature to obtain a hollow spherical ferrous oxide and iron composite electrode material.
[0026] figure 1 is the XRD pattern of the obtained ferrous oxide and iron composite electrode material, by figure 1 The diffraction peaks of FeO and Fe can be seen in the material.
[0027] figure 2 and image 3 It is the morphology of the ferrous oxide and iron composite electrode material prepared in Example 1 observed under a scanning electron microscope. It can ...
Embodiment 2
[0032] Add 1g of ferric chloride hexahydrate, 6g of sodium acetate and 0.9g of polyethylene glycol into 80ml of ethylene glycol, and ultrasonically oscillate for 200 minutes to obtain a uniform mixed solution; React for 24 hours. The hydrothermal product was successively washed with deionized water and absolute ethanol, and vacuum freeze-dried at a temperature of 0°C and a pressure of 101kPa for 30 hours to obtain the product; Calcined for 5 hours and cooled to room temperature to obtain a hollow spherical ferrous oxide and iron composite electrode material.
[0033] The composite electrode material prepared in Example 2 and the polyvinylidene fluoride binder are prepared into an electrode in a mass ratio of 4:1, and the electrolyte solute is LiPF 6 , the solvent is mixed by ethylene carbonate, diethyl carbonate and dimethyl carbonate in a volume ratio of 1:1:1, LiPF 6 The concentration is 1mol / L, and the electrode and electrolyte are assembled to form a button battery.
