| description | The utility model relates to a pole piece lithium supplementing device which comprises a pole piece unwinding device, a lithium supplementing device and a lithium supplementing device, the first lithium strip unwinding device is used for conveying a first lithium strip; the first calendaring transfer device comprises a first calendaring roller and a first transfer roller, and the surface release force of the first calendaring roller is smaller than that of the first transfer roller; the first lithium strip is conveyed between the first calendering roller and the first transfer roller and is calendered into the first lithium foil, the first lithium foil is attached to the first transfer roller, and the first transfer roller transfers the first lithium foil to one surface of the pole piece. According to the lithium supplement device, the release agent is directly coated on the calendering roller and the transfer roller, so that lithium supplement without an auxiliary film is realized, and the lithium supplement |
