Abstract

To provide a metal negative electrode for a secondary battery using a lithium metal film that improves battery characteristics, a manufacturing method for the same, and an application using the same.SOLUTION: A negative electrode for a secondary battery includes a current collector and a lithium metal film located on the current collector. The lithium metal film consists of crystal grains having a grain size in a range greater than 15 μm and less than or equal to 100 μm. A manufacturing method of the negative electrode for a secondary battery includes melting lithium metal, dropping molten lithium metal onto the current collector, and pressing the lithium metal dropped by a metal plate together with the current collector.SELECTED DRAWING: Figure 1
