Embodiment 1
[0029] A polyoxometalate carbon nanotube electrode material for lithium-ion batteries: the electrode material comprises lithium phosphomolybdate Li 3 PMo 12 o 40 with solid carbon nanotubes.
[0030] Its preparation method is:
[0031] (1) Weigh phosphomolybdic acid H at a mass ratio of 1:9 3 PMo 12 o 40 and solid carbon nanotubes, and respectively configure the same volume of aqueous solution;
[0032] (2) Phosphomolybdic acid H 3 PMo 12 o 40 The solution was slowly added dropwise into the carbon nanotube solution, and reacted at room temperature for 10 hours;
[0033] (3) Then add lithium hydroxide solution (LiOH) (lithium hydroxide and H 3 PMo 12 o 40 The molar ratio is 3:1) to react for 6 hours to obtain a solid precipitate;
[0034] (4) Wash the obtained solid with distilled water and alcohol repeatedly until the filtrate is colorless (or clear), and dry the solid in a vacuum oven at 85°C for 8-12 hours to obtain the electrode material Li 3 PMo 12 o 40 - C...
