Abstract
A secondary battery and an electric apparatus. The secondary battery includes an electrolyte solution and a separator, the separator including a base film and a coating located on at least one side of the base film, where the secondary battery satisfies: 0.5≤G×H/(10×σ)≤13, G is a Gurley value of the base film, with a unit of s, H is a thickness of the coating, with a unit of μm, and σ is an electrical conductivity of the electrolyte solution at 25° C., with a unit of mS/cm.
