Estimating the term…
A lithium metal battery includes a positive electrode plate, a negative electrode plate, and an electrolyte. The electrolyte includes a lithium salt and a solvent. A molar concentration of the lithium salt is A mol/L, where 2≤A≤4. The solvent includes a first solvent. Based on a total mass of the solvent in the electrolyte, a mass percentage of the first solvent is B %, satisfying 10≤B≤50. The lithium metal battery satisfies a relation: 40≤A×B≤100. In the lithium metal battery and the electronic apparatus provided in this application, cycling performance and safety performance of the lithium metal battery are improved through the adjustment of components of a fluorine-containing solvent in the electrolyte and components and structure of an SEI film at a negative electrode side.
