[0024] Below, the present invention will be further described by the following examples, which will help to understand the present invention, but do not limit the content of the present invention:
[0025] (1) After mixing water and dilute hydrochloric acid, add potassium permanganate to it, dissolve and form a solution under stirring, transfer it to a reaction kettle, put a titanium foil of appropriate size into the kettle, and react 24 pieces at 180°C Hour, obtain manganese dioxide nanowire array;
[0026] (2) Rinse the product obtained in the above steps, dry it, put it into a hydrothermal reaction kettle filled with polyvinylpyrrolidone, and react at 200°C for 4 hours to obtain the manganese oxyhydroxide nanowire array;
[0027] (3) Manganese oxyhydroxide nanowire arrays were calcined at 500 °C in air for 4 hours to obtain manganese trioxide nanowire arrays; after mixing manganese oxyhydroxide nanowire arrays with ethanol solution of lithium nitrate, they were calcined at...
