Abstract
The present disclosure provides a lithium-ion secondary battery, which comprises a positive electrode plate, a negative electrode plate, a separator and an electrolyte. The lithium-ion secondary battery satisfies a relationship: 1.5≤(m×C)/(ρ×Cap)≤6.5. In the present disclosure, by comprehensively considering the rated capacity of the battery, the mass of the electrolyte and the intrinsic parameters of the electrolyte and reasonably quantifying the relationship thereof, the lithium-ion secondary battery can have good dynamics performance and longer cycle life at the same time.
