The invention provides microporous layer slurry as well as a preparation method, an optimization method and application thereof, and the optimization method of the microporous layer slurry comprises the following steps: presetting a target permeability of a microporous layer; presetting a target viscosity value and a target median particle size of the microporous layer slurry and target surface tension and a target boiling point of a solvent according to the target permeability; according to the target surface tension and the target boiling point, taking a solvent conforming to the target surface tension and the target boiling point as a target solvent; testing the first viscosity of different conductive agents to the target solvent, and screening the conductive agent with the first viscosity meeting the target viscosity value requirement as a target conductive agent; and mixing the target solvent, the target conductive agent, the preset water repellent agent and the preset auxiliary agent according to differ
