[0032] Example 1:
[0033] Preparation process of Na-Mn-O electrode material:
[0034] (1) Add 2 g of manganese trioxide and 0 g of titanium dioxide powder to 40 mL of 10 mol / L sodium hydroxide solution successively, and use a magnetic stirrer at room temperature to stir for 30 min at 350 r / min until the powder is dissolved.
[0035] (2) Move the solution obtained in (1) from the magnetic stirrer to an ultrasonic cleaner, and sonicate it under 70W power for 30 minutes until it is completely dispersed, and then move the completely dispersed solution to the magnetic stirrer again, and stir at 450r / min. 30min.
[0036] (3) Move the completely dissolved solution to the hydrothermal synthesis reaction kettle, tighten the lid of the kettle, and move it into a constant temperature oven. Heating at a constant temperature of 170°C for 60 hours to obtain a preliminary product.
[0037] (4) Collect the preliminary product step by step into the centrifuge tube, place the centrifuge tube symmetric...
