Title:
リチウムイオン電池用セパレータ
Document Type and Number:
Japanese Patent JP7000540
Kind Code:
B2
Abstract:
A separator for an electricity storage device comprising a first porous layer (layer A) with a crosslinked structure that includes a silane-modified polyolefin, and a second porous layer (layer B) that includes inorganic particles, wherein the ratio of the thickness (TA) of layer A with respect to the thickness (TB) of layer B (TA/TB), determined as described in the description, is 0.22 to 14, andwherein layer A has a shutdown temperature of 130°C to 160°C and a meltdown temperature of 200°C or higher, as measured based on the electrical resistance under pressure of 10 MPa and determined as described in the description.
