Claim 6:
7. The positive electrode plate according to claim 5, wherein
the positive electrode plate has an infiltration increase rate I ranging from 2% to 20%;

wherein I=(I2−I1)/I1×100%;

I2 is an infiltration rate of the positive electrode plate in an electrolyte; and
I1 is an infiltration rate of a positive electrode plate containing no polyether polyol in an electrolyte;
wherein the positive electrode plate used for determining I1 is the same as the positive electrode plate used for determining I2, differing only in that the positive electrode plate used for determining I1 contains no polyether polyol, and the positive electrode plate used for determining I2 contains the polyether polyol.
