The present disclosure provides a black phosphorus negative electrode, which includes: a current collector, an induced deposition layer and a black phosphorus film, the induced deposition layer is located on the current collector, the induced deposition layer includes a phosphorus-containing alloy for inducing the deposition of the black phosphorus film, and the induced deposition layer The layer is formed on the induced deposition layer by magnetron sputtering, and the induced deposition layer covers the current collector. In the black phosphorus negative electrode, the black phosphorus film is epitaxially grown on the induced deposition layer by means of magnetron sputtering. Compared with the black phosphorus nanosheet powder material in the traditional technology, the black phosphorus negative electrode can effectively improve the discharge specific capacity and the charge-discharge cycle stability of the negative electrode. |
