Negative pole piece and battery comprising same

The invention relates to the technical field of lithium ion batteries, in particular to a negative pole piece and a battery comprising the negative pole piece, the negative pole piece comprises a negative current collector, a lithium metal deposition layer which is arranged on the negative current collector and is in contact with the negative current collector, and a lithium metal isolation layer which is arranged on one side, deviating from the negative current collector, of the lithium metal deposition layer; the lithium metal deposition layer comprises silver; the lithium metal isolation layer comprises conductive carbon and solid electrolyte, the lithium metal deposition layer is arranged on the negative electrode current collector and comprises silver metal, and the lithium metal isolation layer comprises conductive carbon and solid electrolyte. The combination of the two greatly improves the reaction of the lithium metal and the electrolyte in the all-solid-state battery and the non-uniform deposition a
