摘要： An ultra high molecular weight polyethylene (UHMWPE) membrane has at least one nanoporous UHMWPE film, where each of the nanoporous UHMWPE film is biaxial oriented with a thickness of 0.1 to 12 μm and pores that exclude particles in excess of 10 nm with a total porosity of 65 to 75 percent. The nanoporous UHMWPE film can be coated or laminated by a hydrophilic polymer to form a Janus membrane and can be made with a multilayer composite structure. The UHMWPE membrane can be used in a device for molecular distillation (MD), reverse osmosis (RO), or forward osmosis (FO).

摘要： An all-solid-state battery system having a solid-state electrolyte composite is provided. The solid-state electrolyte composite includes a porous framework providing support and mechanical strength for the solid-state electrolyte composite and a plurality of ionic conductors filling voids of the porous framework for maximizing ionic conductance of the solid-state electrolyte composite. The porous framework may be made of ultra-high-molecular-weight polyethylene (UHMWPE) polymers and the plurality of ionic conductors may be made of poly(ethylene oxide)-LiN(SO2CF3)2 (PEO-LiTFSI) polymers. The all-solid-state battery system includes battery cells each including a cathode current collector, a cathode disposed beneath and connected to the cathode current collector, the solid-state electrolyte composite disposed beneath and connected to the cathode, an anode disposed beneath and connected to the solid-state electrolyte composite, and an anode current collector disposed beneath and connected to the anode.
