| titleOfInvention | Lithium supplementing method, negative plate and secondary battery |
| abstract | The invention belongs to the technical field of secondary batteries, and particularly relates to a lithium supplementing method and a secondary battery, which comprise the following steps: step S1, coating active substances on the surface of the negative current collector, and drying to obtain a pretreatment sheet; s2, selecting a metal lithium sheet, laminating the metal lithium sheet and the pretreatment sheet, placing the metal lithium sheet and the pretreatment sheet into a sealed box, heating the sealed box, and adjusting a first vacuum degree; step S3, introducing solvent vapor into the sealed box, adjusting the second vacuum degree, and standing at constant pressure; and step S4, adjusting the third vacuum degree, and standing at constant pressure to obtain the lithium-supplement negative plate. The lithium supplementing method can conveniently and rapidly supplement lithium for the negative electrode in large batch, active substances are not affected after the lithium is supplemented, the lithium is supplemented uniformly and rapidly, the active substances are not easy to fall off, and the obtained lithium supplementing electrode sheet can be directly used for the next procedure, so that the time cost is greatly saved. |
