Abstract: The present invention relates to the technical field of lithium batteries, and in particular, to a lithium battery separator and a lithium battery. The separator comprises a block polymer, the porosity of the separator is p, the mass percentage of the block polymer relative to the separator is w, and the relationship between the porosity p of the separator and the relative mass percentage w of the block polymer satisfies that (1−w)/3
