  "textContent": "A battery includes a positive electrode plate, a negative electrode plate, and an electrolyte solution. The negative electrode plate includes a negative electrode current collector including a copper foil and a negative electrode active material layer including a negative electrode active material which including a silicon-based active material, the electrolyte solution includes lithium bis(trifluoromethanesulfonyl)imide; and the battery satisfies following relationship: B−10A−C/10+3≥0; A is a grain size of copper foil, in a unit of m; B is a mess percentage of lithium bis(trifluoromethanesulfonyl)imide in the electrolyte solution, in a unit of wt %; C is a mass percentage of the silicon-based active material in the negative electrode active material, in a unit of wt %, and C≤50. The battery may significantly alleviate silicon negative electrode expansion while enhance the kinetic performance and cycling stability of the battery under room-temperature.",
