A method for manufacturing a crosslinked polyolefin separator and a separator are provided. The method includes putting a polyolefin and a polyolefin elastomer into an extruder first, and putting an alkoxy silane containing a carbon-carbon double bond functional group, an initiator and a crosslinking catalyst to form the separator. The crosslinked polyolefin separator has high meltdown temperature and low shutdown temperature.

Separators, materials, and processes for producing electrochemical cells, for example, lithium (Li) metal batteries, and electrochemical cells produced therefrom. Such a separator includes a permeable membrane formed of a first polymer that is hydrophobic and has oppositely-disposed first and second surfaces, a second polymer that is hydrophilic and is incorporated into the first surface of the first polymer so that the first surface of the first polymer is a hydrophilic surface, and a conductive composite layer on the hydrophilic surface. The composite layer contains at least one layer of a carbonaceous material and an aqueous binder that binds the carbonaceous material together and to the hydrophilic.

Microporous sheet product and methods of making and using the same. In one embodiment, the microporous sheet product is made by a process that includes melt-extruding a sheet material using an extrusion mixture that includes a thermoplastic polymer, a superabsorbent polymer, and a compatibilizing agent. After extrusion, the compatibilizing agent may be removed from the sheet material. When the sheet product is imbibed with a polar or ion-containing liquid, the superabsorbent polymer swells, causing a reduction in the pore size of the sheet product. The exposure also causes some of the superabsorbent polymer to migrate to the exterior of the microporous sheet product. The microporous sheet product may be used, for example, as a battery separator, as a food packaging material, as a diffusion barrier in the ultrafiltration of colloidal matter, and in disposable garments.
