Embodiment 1
[0026] Dissolve 3.5 mmol of nickel acetate tetrahydrate, 1.5 mmol of cobalt acetate tetrahydrate, and 5 mmol of trisodium citrate dihydrate in 50 ml of deionized water to form chelate solution A, and dissolve 5 mmol of sodium ferrocyanide and 1 g of ascorbic acid in A homogeneous solution B was formed in 50 ml of deionized water, and a homogeneous solution C was obtained by dissolving 3 g of NaCl and 1 g of PVP in 100 ml of deionized water. Mix solution A and solution B in 10 ml min -1 The dropping rate is added dropwise to solution C, and at the same time at 50 o N at a temperature of C 2 The reaction was stirred in the atmosphere, and the reaction solution was green. After the dropwise addition, continue to stir and react for 12 h, after standing still for 24 h, after washing with deionized water and alcohol several times, the filter cake was washed at 120 o After vacuum drying at C for 24 h, a blue-green Ni:Co:Fe 7:3:0 multi-component Prussian blue cathode material can b...
Embodiment 2
[0028] Dissolve 2.75 mmol of nickel acetate tetrahydrate, 2.25 mmol of ferrous sulfate heptahydrate and 5 mmol of trisodium citrate dihydrate in 50 ml of deionized water to form chelate solution A, and dissolve 5 mmol of sodium ferrocyanide with 1 g of ascorbic acid. A homogeneous solution B was formed in 50 ml deionized water, and 3 g NaCl and 1 g PVP were dissolved in 100 ml deionized water to obtain a homogeneous solution C. Mix solution A and solution B in 10 ml min-1 The dropping rate is added dropwise to solution C, and at the same time at 50 o N at a temperature of C 2 The reaction was stirred in the atmosphere, and the reaction solution was green. After the dropwise addition, continue to stir and react for 12 h, after standing still for 24 h, after washing with deionized water and alcohol several times, the filter cake was washed at 120 o After vacuum drying at C for 24 h, a blue-green Ni:Co:Fe 5.5:0:4.5 multi-component Prussian blue cathode material can be obtained,...
Embodiment 3
[0030] 2.5 mmol of nickel acetate tetrahydrate, 1 mmol of cobalt acetate tetrahydrate, 1.5 mmol of ferrous sulfate heptahydrate and 5 mmol of trisodium citrate dihydrate were dissolved in 50 ml of deionized water to form chelate solution A, and 5 mmol of sodium ferrocyanide was mixed with 1 g of ascorbic acid was dissolved in 50 ml of deionized water to form a homogeneous solution B, and 3 g of NaCl and 1 g of PVP were dissolved in 100 ml of deionized water to obtain a homogeneous solution C. Mix solution A and solution B in 10 ml min -1 The dropping rate is added dropwise to solution C, and at the same time at 50 o N at a temperature of C 2 The reaction was stirred in the air, and the reaction solution was green. After the dropwise addition was completed, the mixture was then stirred for 12 h, left to stand for 24 h, washed with deionized water and alcohol several times, and then heated at 120 o Dry in a vacuum oven at C for 24 h to obtain a blue-green Ni:Co:Fe multi-compo...
