A kind of preparation method of porous wood carbon modified metal lithium anode material |
| abstract |
A method for preparing a porous charcoal-modified lithium metal negative electrode material, comprising the following steps: (1) taking cross-cut balsa wood and cutting it into wood chips; (2) carbonizing and activating the balsa wood chips at high temperature under a protective atmosphere , obtain the activated balsa wood carbon material; (3) configure metal nitrate or metal acetate solution, place the balsa wood carbon material in the solution to soak for 1-3h, then put it into a tube furnace, put the polytetrafluoroethylene The vinyl fluoride powder was loaded into a porcelain boat and placed in front of the air inlet, and calcined at high temperature to obtain a metal fluoride modified balsa wood carbon material; (4) under the protection of argon, metal lithium was deposited on the metal fluoride modified by electrodeposition method. In the pore structure of the balsa wood carbon material, a modified lithium metal anode material is obtained. The invention can effectively solve the problems of low battery coulombic efficiency and short cycle life caused by the growth of metal lithium dendrites during the charging and discharging process of the metal lithium negative electrode material. |
