Embodiment 1
[0026] Prepare a trimanganese tetraoxide negative electrode material, the preparation method of which is as follows.
[0027] Step 1: Prepare 0.01 M KOH solution and seal it for later use.
[0028] Step 2, 1 g KMnO 4 Dissolve in the 45 mL KOH solution of the above step (1), and stir for five minutes to obtain the mixed solution A.
[0029] Step three, the 0.86 g H 2 C 2 o 4 2H 2 O was added to the mixed solution A in the above step (2) to obtain the mixed solution B.
[0030] Step 4: Put the mixed solution B in the above step (3) into a reaction kettle and seal it, raise the temperature to 180° C. and dry it at a constant temperature for 12 h, and then naturally cool to room temperature to obtain mixed solution C.
[0031] Step 5. Suction filter the mixed solution C of the above step (4), wash with distilled water, then wash with absolute ethanol, and finally place the filter paper with the product in an oven at 60°C for 10 h to obtain tetraoxide Three manganese anode m...
