| titleOfInvention | Preparation method of porous charcoal modified metal lithium negative electrode material |
| abstract | A preparation method of a porous charcoal modified metal lithium negative electrode material comprises the following steps: (1) taking a crosscut balsawood, and cutting the crosscut balsawood into wood chips; (2) carbonizing and activating the balsa wood chips at high temperature under the protective atmosphere to obtain an activated balsa wood carbon material; (3) preparing metal nitrate or metal acetate solution, placing the balsa carbon material in the solution to be soaked for 1-3h, then placing the balsa carbon material in a tube furnace, placing polytetrafluoroethylene powder in a porcelain boat and placing the porcelain boat at the front part of an air inlet, and calcining at high temperature to obtain the balsa carbon material modified by metal fluoride; (4) and depositing the metal lithium into the pore structure of the metal fluoride modified Basapahan carbon material by an electrodeposition method under the protection of argon to obtain the modified metal lithium cathode material. The invention can effectively solve the problems of low coulombic efficiency, short cycle life and the like of the battery caused by the growth of the metal lithium dendrite in the charging and discharging processes of the battery. |
