Abstract
A battery cell includes an electrolyte, positive and negative electrode plates, and a separator provided between the positive and negative electrode plates. The electrolyte includes a lithium salt including lithium hexafluorophosphate, a mass percentage of which with respect to a total mass of the electrolyte ranges from 15% to 20%. The positive/negative electrode plate includes a positive/negative electrode current collector and a positive/negative electrode film layer provided on at least one side of the positive/negative electrode current collector and containing a positive/negative electrode active material. The negative electrode active material contains carbon and silicon. A mass percentage of silicon with respect to a total mass of the negative electrode active material is greater than or equal to 0.3% and less than or equal to 3.0%.
