Claim 2:
3. The method for manufacturing a crosslinked polyolefin separator according to claim 1, wherein:
the diluting agent comprises a first diluting agent, a second diluting agent, and a third diluting agent,
(S1) comprises:
(S11) introducing the polyolefin and the first diluting agent to the extruder, followed by mixing;
(S12) introducing the second diluting agent, the first alkoxysilane containing a carbon-carbon double bonded group, the initiator and the crosslinking catalyst to the extruder, followed by mixing; and
(S13) introducing the third diluting agent and the second alkoxysilane containing a carbon-carbon double bonded group to the extruder, followed by mixing, and carrying out the reactive extrusion,
wherein the first alkoxysilane containing the carbon-carbon double bonded group has a higher boiling point as compared to the second alkoxysilane containing the carbon-carbon double bonded group.
