A kind of preparation method and application of tin selenide-selenium-doped polyacrylonitrile composite potassium ion battery anode 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: a certain amount of tin source, polyacrylonitrile It is mixed and stirred with N-N dimethylformamide, and then electrospinned to obtain PAN/SnCl 2 composite fibers, which are further calcined and selenized to obtain tin selenide-selenium-doped polyacrylonitrile composite potassium ion battery anode materials . The long-term cycle performance of the potassium-ion battery anode material is stable. 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; The specific capacity is still stable at 301 mAh/g. |
