Embodiment 1
[0044] LiFe with a core-shell structure 5 o 8 The preparation method of @PPy supercapacitor electrode material, comprises the following steps:
[0045] (1) First, 0.01 g of CTAB was added to 100 mL of N,N dimethylformamide to obtain mixed solution A.
[0046] (2) Then 0.1g LiFe 5 o 8 The powder and 0.02 g of PPy nanotubes were added to the mixed solution A, and the mixed solution B was obtained by ultrasonication at 600 W for 4 hours.
[0047] (3) Pour the mixed solution B into a three-necked flask, heat and stir in a water bath at 80°C, and feed nitrogen at the same time;
[0048](4) Add 12.5 mL of hydrazine hydrate and 5 mL of methyl mercaptoacetate dropwise to the mixed solution B, and continue to protect with nitrogen for 30 min. After the reaction is carried out for 45 min, stop the reaction with supercooled ethanol;
[0049] (5) After the precipitate obtained after the reaction was washed three times with absolute ethanol and deionized water, vacuum-dried for 10 h, ...
