Negative plate and application thereof

The invention provides a negative plate and application thereof. The negative plate comprises a negative plate substrate and a porous capacitance layer arranged on at least part of the surface of the negative plate substrate, a fast charging parameter K value is comprehensively limited through the specific capacitance and the resistivity of the negative plate and the specific surface area, the average pore size and the thickness of the porous capacitor layer, and when K is larger than or equal to 1, the good fast charging capacity can be achieved.
