Disclosed in the present invention are a lithium metal material, a method for controlling the orientation of crystal faces of a lithium metal, an electrode sheet and a battery. The surface of the lithium metal material has a crystal face (110), a crystal face (211) and a crystal face (200); and the ratio of the intensity of the characteristic peak of the crystal face (110) to the intensity of the characteristic peak of the crystal face (211) is greater than or equal to 3, and the ratio of the intensity of the characteristic peak of the crystal face (110) to the intensity of the characteristic peak of the crystal face (200) is greater than or equal to 3. The intensity of the crystal face (110) on the surface of the lithium metal material is high, and the lithium metal material has the high-exposure crystal face (110) and can be used in a lithium metal battery. Due to a low surface diffusion energy barrier of lithium ions on the lithium crystal face (110), the material tends to form a high-dimensional structure rather than one-dimensional dendrites; therefore, when used in a lithium metal battery, the lithium metal material can effectively reduce the risk of internal short circuits under high-current and long-term cycling conditions.
