| titleOfInvention | Preparation method and application of a tin selenide-selenium-doped polyacrylonitrile composite potassium ion battery negative electrode material |
| abstract | The invention discloses a preparation method and application of a tin selenide-selenium-doped polyacrylonitrile composite potassium ion battery negative electrode material. The experimental process is easy to operate and the conditions are controllable. The technical scheme is as follows: Blending and stirring with N-N dimethylformamide, and then electrospinning to obtain PAN/SnCl 2 composite fibers, which are further calcined and selenized to obtain tin selenide-selenium-doped polyacrylonitrile composite potassium ion battery negative electrode material . The long-term cycle performance of the negative electrode material of the potassium ion battery is stable, and the charge-discharge cycle exceeds 1000 cycles at a current density of 0.5 A/g, and the specific capacity is still stable at 397 mAh/g; after 2500 cycles of charge-discharge cycle at a current density of 1 A/g The specific capacity is still stable at 301 mAh/g. |
